3.1 碟形飞行器作为一种在太阳系内的未来太空战斗机,其主要任务是在最冰冷最强大的“气液固三相流体风暴”的木星、土星、天王星、海王星等气态行星上飞行和战斗(随着未来对气态行星资源的争夺),还要在最高温最狂暴的“电磁等离子体风暴”及可怕引力的伟大太阳上面去飞行和战斗(随着未来对太阳资源的争夺)。即碟形飞行器必须在太阳和各大行星的大气层内飞行,如果物理学能坚决拒绝“反重力反引力反质量”,则碟形飞行器必须依靠空气动力学来飞行(特别是通过“空气动力学升力”来对抗星球的引力,以及得到高过载或向心力矩等)。但在空气动力学中,“涡旋”(具有涡量或环量)是机翼绕流的重要现象,正是依靠“涡旋”才使低速机翼获得主要的“升力”;那么碟形飞行器在低速飞行或中低空悬停时,其上用以产生主要“气动升力”的“涡旋”,也必须要和这些无比强大的行星级风暴和恒星级风暴的强大程度和控制性同等级才行。而这些强大的风暴或巨型涡旋,在物理方面也都有一些相似的基本特征。比如,地球上的台风/飓风,在其中心处都有一个管状的“粘性涡核”,是由管状的侧壁气流柱组成,是由于外部周围四面八方的低速来流向中心挤压,流体由于角动量守恒定律而加速,和机械能守恒定律的伯努利原理而减低气压(流体的动压增加而静压减少)到最大,高速的流体沿圆周旋转就有一个“向心力的反作用力”(“离心力”)而形成了一个管状的“涡核”(是“涡量”最密集的区域),并且,其内圆柱状的空腔是一个“中心无风低压区”,这是由于其侧壁的高速旋转的圆管形的气流柱的“粘性”,大量“吸附(剪切、诱导、扰动、渗混)了中心的空气进入侧壁流体而造成了低气压,出现“中心低压区”,以及在台风/飓风的上部利用流体的“粘性”把“涡核的涡量”在上部向外传递耗散时形成的有序流动流体(同时,如果没有流体的“粘性”也不会得到低速机翼上表面的主要的“低静压区或气动升力”)。
3.1 As a kind of future spacefighter which will be flying in our solar system,the major task of the saucer-shaped spacecraft will be flying and fighting on the gas giants of Jupiter,Saturn,Uranus,and Naptune which always have the iciest and mightiest of three-phase fluids(gas,liquid and solid) storm (when we will be able to compete for resources on the gas giants),and on the sun which always have the hottest and fiercest of electromagnetic-plasma-storm(solar-storm) and tremendous gravity(when we will be able to compete for resources on the sun).Then it will have to be flying in the atmospheres of sun and all the planets.If the physics will firmly reject the theories about anti-gravity and anti-mass,the saucer-shaped spacecraft's flight will have to rely on the Aerodynamics(especially use the lift-force to against the gravity of planet or star, and obtain the high overload and concentric-torque). In the Aerodynamics,the vortex(possessing the vorticity or circulation) is an important phenomenon in the flow field around the low-speed airfoils and wings,and the low-speed airfoils and wings will obtain the lift-force which is precisely relyed on the vortex.So when the saucer-shaped spacecraft will be flying at low speed or hovering in mid and low level,the vortex that generating the lift-force on it will have to be the same grade of the intensity and controllability as the planetary-storm and solar-storm. These strong storms and great vortexes always have some similarly fundamental character in physics.For instance,the hurricane/typhoon always have a tubular "viscous-vortex-core" that consisted of a large amount of tubular side-wall-fluids,which is due to the circular low-speed inflow squeeze each other towards the center.Then the low-speed inflow will be accelerated owing to the law of conservation of angular momentum,and the air-pressure will be lowered to the maximum extent according to Bernoulli equation under the law of conservation of mechanical energy (when the dynamic-pressure will be rised then the static-pressure will be lowered at the same time).The high-speed fluids will rotate along the circumference and obtain a reaction-force of centripetal-force (centrifugal-force),then form a tubular "viscous-vortex-core" (which is the greatest concentrations of the vorticity).And the cylindrical cystic-spaces is a calm low-pressure central-area.Because the viscosity of the tubular high-speed-rotating side-wall-fluids will be absorbing (shearing or inducing) a large quantity of the cystic-spaces airs to cause the low-air-pressure,and forming the calm low-pressure central-area.And the viscosity of the fluids will deliver and dissipate the vorticity of vortex-core towards outside in the upper hurricane/typhoon to form an orderly-flow-fluids.(In the same time,if there is not the vorticity of fluids,the low-speed airfoils and wings will not obtain the low-static-pressure-area or aerodynamic-lift.)

3.2 一般认为,流体中的宏观“涡旋”只能以两种形态体系存在(即“自然界两大类涡旋”):一种形态体系的“涡旋”在其两端终止于壁面(“二维的旋涡”),就像水里的漩涡,终止于水面或水底,以及正像上述的台风/飓风,终止于海面及对流层顶部。另一种形态体系的“涡旋”围成一个封闭的“涡环”(“三维的涡环”),比如空中的烟圈和蒲公英种子上的“环形分离涡或分离涡环”。其中,蒲公英种子上方的流体形成的是一个“环形分离涡”,内含一个比较稳定的“涡核”,其整个“涡环”可以在比较宽的风速范围内稳定存在,为蒲公英种子提供“升力”(明显优于军用降落伞),并且气动效率高,节约材料,流动稳定性高,对风向突变的适应性好,其作为一种产生“升力”的“涡环”的飞行机理一经公开就已被广泛的猜想可能为“飞碟之谜”的“升力相关的涡旋或升力涡”。另外,空中的烟圈的“涡环”一旦在空中成型,则其内“涡核”的旋转流体因为有“粘性”而把“涡量”持续向外传递耗散,直到“涡核”消失,整个“涡环”接着溃散,空中的烟圈的稳定性较差,容易受风扰动变形。但上述两种“涡环”结构上类似,都有一个“涡核”(是“涡量”最密集的区域)。差别只是,蒲公英种子上的“涡环”是一种附着在物体表面的“分离涡”,而空中的烟圈的“涡环”是一种脱离开物体表面的“脱体涡”。
3.2 It is generally recognized that the macroscopic-vortex in the fluids will only exist in two forms(namely natural two-broad-categories of vortexes.).And the first kind of macroscopic-vortex will be terminated in both ends (two-dimensional vortex),just like an eddy in the water which will be terminated in the surface or bottom of the water,or like the hurricane/typhoon which will be terminated in the surface of the ocean or the top of the troposphere.Then the second kind of macroscopic-vortex will enclose a vortex-ring (three-dimensional vortex),just like a smoke-ring in the air and the separated-vortex-ring (the annular-separation-vortex) above the dandelion seeds.Among them,the fluids above the dandelion seeds will form a annular-separation-vortex,which contains a single relative stable vortex-core,that will exist in a wide speed-range of wind,and generate a stable aerodynamic-lift (that is obviously better than that of the service parachute).It is inferred that it has advantages of high aerodynamic-efficiency,flow-stability,wind-direction-mutation adaptability and saving materials.It is speculated that its flight mechanism generating aerodynamic-lift using the vortex-ring could be the vortex-about-lift (the lift-vortex) of the mystery of flying saucers.In addition,once the vortex-ring of the smoke-ring in the air will be generated,the viscosity of the rotating fluids in the vortex-core will deliver and dissipate the vorticity of vortex-core towards outside.Until the vortex-core disappear,the vortex-ring or smoke-ring will collapse.The flow-stability of the smoke-ring in the air is often low,and easy to deform under the wind disturbance.But both the above-mentioned vortex-ring have the similar structure,and have a vortex-core which is the greatest concentrations of the vorticity.The difference is that the vortex-ring above the dandelion seeds is a kind of attached-vortex attaching to the outer surface of body,and the vortex-ring of the smoke-ring in the air is a kind of detached-vortex detaching to the outer surface of body.

3.3 昆虫翅膀也是利用“涡旋”产生高效率的“气动升力”。其翅膀向前下方拍动时其前缘形成了一种“前缘分离涡”,是一种“螺线管型涡旋”,在小尺寸小速度的空气运动中的流体的“粘性”比通常强得多,当然这个“前缘分离涡”也形成一个“涡核”。“涡核”的流体高速旋转流动的“向心力的反作用力”(“离心力”)和“粘性”形成了涡核内的空气分子的低密度低压区,也诱导出一个从翼尖到翼根的高速的“附着流”,两者因符合机械能守恒定律的伯努利原理其动压增大则静压减小,两者合成的低压区就是翅膀上表面的主要升力区。不过,昆虫翅膀上的这种分离涡到了后部想要离开边缘也有“下洗趋势”,初看来这个分离涡的“下洗趋势”仍然保持着强烈的旋转,这将会有高阻力和低效率,但实际观察出此时翼尖形成的“脱体涡”(也叫“尾涡”)的尾端已经接续起了前缘分离涡的尾端(两个涡旋的旋转轴相连接且流体的旋转方向一致),这类似于飞机机翼后缘的一种“起动涡”,所以两者的接续形成了一个典型的“涡环”,也符合一种经典机翼的“涡环”结构的等效气动模型。那么,昆虫翅膀向后上方返回拍动时,通过一种所谓的“尾涡捕获”机理,让“尾涡”中的能量得到重复利用,最终形成一个消除了“尾涡”流体的旋转性质后的单一直线的斜下方向的“下洗流”。在此推测为由昆虫翅膀的上表面在向后上方返回拍动时在横向上去阻断“尾涡”,“尾涡”的流体在昆虫的“网状翅脉reticulate vein”之间因受高压而形成的一种类似“伞状凹陷”的结构中被阻断和冲压并反射喷出,从而得到高压喷射流(特别是有时候当两个翅膀在后上方合拢相拍,形成了类似“发动机燃烧室和收敛喷管”的形状,从而压缩流体后再喷出一种向后的纵向射流,这与与鱼类的尾鳍利用“反向的Karman涡街”得到推进射流的情况有一定的相似性),这是一种高推力,也造成了某些情况下翅膀后拍时得到了更高的升力或向前加速的现象。所以这就造成了现实中昆虫翅膀的高升力高加速和高效率。
3.3 The insect wings will also be using the vortex to obtain the aerodynamic-lift. It will be formed a leading-edge-vortex above the insect wings when it is flapping toward fore-downwards,which is a solenoidal-vortex.And the viscosity of the small-size and low-speed fluids in the air is much high than usual.Of cause,this leading-edge-vortex also have a viscous-vortex-core.The viscosity and reaction-force of centripetal-force(centrifugal-force) of the rotating fluids in the vortex-core will construct low density/pressure area in the vortex-core,then it will induce a attached-flow from wingtip to wing-root,both them meet the Bernoulli equation under the law of conservation of mechanical energy (when the dynamic-pressure will be rised then the static-pressure will be lowered at the same time),and together they forming a low density/pressure area will be the main aerodynamic-lift area above the insect-wings.This leading-edge-vortex of the insect wings will also have a downwash tendency when it will leave the trailing edge,but it seem to hold a high-speed rotation.It will has a poor efficiency and high resistance.But in fact,both the tail of the detached-vortex (wake-vortex) of the wingtip and the tail of the leading-edge-vortex have been connected when they are observed (together this two vortexes have a same axis/direction of rotation.),this is like the starting-vortex of the trailing edge of aircraft wing.So the connection of this two vortexes will form a typical separated-vortex-ring,which will meet an equivalent aerodynamic-model under a classical vortex-ring structure of aircraft wing.When the insect wings is flapping toward back-upwards,the energy of wake-vortex will be reused by a wake-vortex-capture mechanism.In the end,the rotating character of the wake-vortex have been eliminated,and there is a single straight downwash-flow inclined downward.And it has been infered that the wake-vortex has been blocked by the insect wings when flapping toward back-upwards,the fluids of wake-vortex under high-pressure has been blocked/punched/reflected and been ejected in the structure of umbrella-shaped-depression between the reticulate-vein of insect wings,so there is a single straight high-pressure jet (downwash-flow) inclined downward (especially when the insect wings are flapping toward back-upwards and closured(clap-fling mechanism),it will form a shape of engine-combustor/convergent-nozzle,and compress the fluids to spout a kind of backward longitudinal-jet,which is similar to the circumstance that the caudal-fin of fish obtain the propulsive jet using the reverse karman-vortex-street.).This is a kind of high thrust,and it will appear a circumstance which will generate a far higher lift-force or acceleration,when the insect wings are flapping toward back-upwards.So it has developed the reality that the insect wings always obtain a high efficiency,a high acceleration and a high lift-force.

3.4 大鸟的滑翔和低速飞机等也是利用“涡旋”产生气动升力的,和昆虫翅膀一样,也符合一种经典机翼的“涡环”结构的等效气动模型,这个抽象的机翼“涡环”可以看成由四部分组成,其中围绕机翼的部分的涡称之为“附着涡”,“附着涡”终止于翼稍,拖出两组“脱体脱”(尾涡或尾迹涡)他们与“起动涡”一起形成一组封闭的“涡环”。其中“附着涡”可以具体化为当机翼前缘在前方来流的冲压下因“上洗”作用而形成附着于机翼上部的曲率较大的凸面上的流体,“附着涡”的流体由角动量守恒定律而加速,和机械能守恒定律的伯努利原理而减低气压(流体的动压增加而静压减少),“附着涡”在机翼上表面的较平坦部分可诱导出较平直的“附着流”(其下与机翼表面蒙皮之间还有一个“附面层或边界层”的流体层),因为流体的“粘性”,而“吸附(剪切、诱导、扰动、渗混)”了机翼表面的“附面层”的空气分子一起流走,也“剪切”了机翼上方大量的来流成为“剪切流”向后下方流动,“附着涡”和“附着流”的降低的静压因而传导于“附面层”而形成机翼上表面的“低压区”,产生主要升力。“附着流”流向后下方,就有一个“下洗”的趋势,在机翼翼梢的“尾涡”的影响下可形成机翼后方的“下洗流”。根据动量定理和动量守恒,“升力”在此可以简单考虑成,一个等效于机翼动量的“附着涡”的“涡量”(“环量”),诱导出上方来流在垂直方向的“动量的变化量”。机翼的“总环量”等于上表面“附着涡”加上后上方“剪切流”的“总涡量”,与机翼的主要“升力”直接相关,而机翼蒙皮表面流体的“附面层”的流动形式和压强,也与机翼的“升力”最终相关。因为机翼上表面的“附着涡”和“附着流”要把低静压传导于附面层的流体才能得到机翼的低压区(主要升力),而如果附面层以“层流附面层”的形式流动则可以得到升力,但是如果附面层以“湍流附面层”的形式流动则静压提高了就失去了升力,当机翼的迎角超过了“失速迎角”时,机翼上表面的附面层就是全部成了“湍流附面层”,即飞机会因“失速”(失去升力)坠落。所以,低速机翼的流体方面主要研究的是“附着涡”(和“附着流”)和“附面层”。
3.4 The gliding of big bird and the low-speed aircraft also rely on the vortex that generating the lift-force to flight.It's the same with the insect wings,this will meet an equivalent aerodynamic-model under a classical vortex-ring structure of aircraft wing.This abstract vortex-ring of low-speed aircraft wings will consist of four parts,among them the vortex around the wing's surface is usually called the attached-vortex which terminates in the wingtip,and it continue to drag behind two detached-vortex (wake-vortex or trailing-vortex),and they aroud a vortex-ring together with the starting-vortex. Among them,the attached-vortex will concrete into the fluids attaching above the convex surface with larger curvature when the leading-edge of wings are punched by the incoming-flow.The fluids of the attached-vortex will be accelerated as it meet the law of conservation of angular momentum,and the air-pressure will be lowered to the maximum extent according to Bernoulli equation under the law of conservation of mechanical energy (when the dynamic-pressure will be rised,then the static-pressure will be lowered at the same time).The attached-vortex will induce a relative straight attached-flow above the flat surface of wings (between this attached-flow and the surface-skin also has a boundary-layer.).Because the viscosity of the fluids will be absorbing (shearing or inducing) a large quantity of the air-molecules in the boundary-layer to flow away,and shearing the incoming-flow (become the shear-flow) above the wings to flow towards back-downwards.Then the low-air-pressure of the attached-vortex/attached-flow will be transmitted to the boundary-layer,and forming the low-pressure-area above the wings.The attached-flow will flow towards back-downwards,then have a downwash tendency,and it will form a downwash-flow behind the wings as the effect of the wingtip's wake-vortex.According to Momentum Theorem and Momentum Conservation,the lift-force will be recognized to be a vorticity(circulation) of the attached-vortex equivalent to wing's momentum,that induce a momentum change of the incoming-flow in the vertical direction.The total circulation of the wings equals the total vorticity coming from the upper-surface's attached-vortex plusing the rear shear-flow,that is tightly related to the main lift-force of wings.And the flow-pattern and dynamic-pressure/static-pressure of the boundary-layer above the wings is also related to obtaining the lift-force.Only the low-air-pressure of the attached-vortex/attached-flow will be transmitted to the boundary-layer,then the low-pressure-area (the main lift-force) above the wings will be formed.The wings will maintain the lift-force if the boundary-layer will be the laminar-boundary-layer,otherwise will lose the lift-force if be the turbulent-boundary-layer.When the wing's angle-of-attack will be larger than the stall-angle-of-attack,the boundary-layer of the upper-surface of the wings will be wholly the turbulent-boundary-layer,then the aircraft will crash due to stall (losing the lift-force).So the fluid-study about the low-speed airfoils and wings will always mainly relate to the attached-vortex(attached-flow) and the boundary-layer.

3.5 低超声速的飞机机翼很多是大后掠三角翼,有较大的后掠角和尖锐的前缘,而不像低速机翼那么平直和前缘钝圆,其在起飞和降落的需要高升力的低速时段中,可以采用较大的迎角而让机翼下部来流从前缘分离,并卷成一种“前缘分离涡”(“螺线管形涡旋”),此分离涡有一个“主要核涡”(甚至还有“第二涡旋”),当然三角翼前缘的这个分离涡“吸附(剪切、诱导、扰动、渗混)”了大量的周围气流并向后下方旋转流动(也同时诱导出机翼上表面的比较平直流动的“附着流”,此“附着流”流速高则动压高而静压降低可产生机翼上表面的主要升力),就有一个“下洗”的趋势,并可以与“翼尖脱体涡”相混合,但是无法让其最终“消除旋转性质”(比平直机翼形成的翼尖涡的流体旋转性要强得多),所以是浪费了更大的能量,此时因产生升力而引起的阻力(诱导阻力)明显更大(相较于低速的平直机翼)。此“前缘分离涡”的涡核流速很高则动压很高而静压很低,有助于提高机翼上表面的升力。而三角翼总升力等于附着流的升力和前缘分离涡的升力之和。
3.5 The wing of low-supersonic aircraft is mostly the high-sweepback-delta-wing,which has high angle-of-sweepback and sharp leading-edge.It is unlike the low-speed airfoil-and-wing which has usually straight-wing and blunt leading-edge.When it require high lift-force at the time of take-off and landing,it will adopt a high angle-of-attack to induce the incoming-flow separating from the sharp leading-edge and becoming the leading-edge-vortex (separated-vortex or solenoidal-vortex).This separated-vortex has always a primary-vortex-core (even has a secondary-vortex),and it will be absorbing (shearing or inducing) a large quantity of the air-molecules in the boundary-layer to flow away,and shearing the incoming-flow (become the shear-flow) above the wings to flow towards back-downwards.Then the low-air-pressure of the attached-vortex/attached-flow will be transmitted to the boundary-layer,and forming the low-pressure-area above the wings.The attached-flow will flow towards back-downwards,then have a downwash tendency,and it will form a downwash-flow behind the wing as the effect of the wingtip's wake-vortex.And this leading-edge-vortex will mix with the wingtip's wake-vortex behind the wing,but the fluid's rotating-characteristic will not be eliminated (the fluid's rotation will be more violent than that of the straight-wing-wingtip's wake-vortex.).So it will be consuming more energies than usual,then the aerodynamic-resistance (induced-drag) will be obviously larger than that of the straight-wing at the time of low-speed.The primary-vortex-core of this leading-edge-vortex will be flowing at high-speed,so the dynamic-pressure is high and the static-pressure is low that will contribute to generate a larger lift-force of the wing's upper-surface.Then the total lift-force of the high-sweepback-delta-wing will be equal the lift-force of the attached-flow plusing the lift-force of the leading-edge-vortex.

3.6 超声速甚至高超声速飞行的升力(包括阻力),其与宏观大尺寸的“涡旋”的关系越来越少,而越来越多是“激波”的世界(高空飞行因为空气密度低则激波后的压缩空气是高超声速飞机产生升力的主角,中低空因为空气密度高则“膨胀波”也是主角)。超声速和高超声速的机翼可以等效于一个很薄的平板(一定程度类似于“风筝”),飞行时有一个不大的迎角,来流流过有迎角的平板的前缘在上部形成“膨胀波”,超声速空气流经过膨胀波后得到加速和静压强降低,则上部形成“低压区”得到上表面的升力;而机翼的前缘在下部却是形成“激波”,超声速空气流经过激波后是减速的和静压强增加,激波后的空气分子密度和温度增加明显,则机翼下部形成“高压区”得到下表面的升力,特别是在高超声速的“乘波体”飞行器采用了“附体激波”,通过贴近下表面的“激波”来压缩空气产生所谓的“激波升力”或“压缩升力”。高超声速时的“激波”是被压缩成了一层很薄的高密度高温高压强的空气分子层。而飞行速度越高(高超声速)下部的“激波”越倾斜越接近表面,则会有一个机体下部的压力或升力的突然增大现象,主要是“激波”可以在贴近机体下表面时使飞行器得到高效率的升力(气动阻力只会随着飞行速度的提高而略微的提升),这相当于“飞行器乘着激波飞行”(乘波体)。同时高超声速前方来流经过“激波”后其大量的“动能”被消耗成“热能”,则“激波”就产生了总的飞行阻力的主要部分。另外,在机体下部的“激波”后的高密度高温高压强的附面层,也会由“层流”转化成“湍流”,而出现升力的异常、高脉动和传热异常现象。高超声速的“乘波体”飞行时就像是在一个“激波”之上滑翔,如同在水里的冲浪板的滑行,而如果是在大气层的高层与太空边缘,有导弹弹头或空天飞机可以一个波谷下降冲入大气层内,再以一个大迎角得到高升力,以一个波峰上升冲出大气层,的反复的“正弦波跳跃滑翔式飞行”(“sanger弹道”),就像旋转的扁圆的碟形石片在水面上不断“打水漂”,可以更有效更节能更高机动性。
3.6 The aerodynamic-lift and aerodynamic-resistance (air-resistance) under the supersonic and hypersonic flight will have less and less relation to the macroscopical vortex,but more and more relation to the shock-wave (the compressed-air behind the shock-wave will be the main-source of lift-force as the low-air-density when hypersonic-flighting on the upper-air,and the expansion-wave will also be the main-source of lift-force as the high-air-density when hypersonic-flighting on the upper-air when supersonic-flighting in mid/low-level-air.).The wing under the supersonic and hypersonic flight will be equal to a thin flat plate (which is similar to a kite.).This flat-plate-wing will have a modest angle-of-attack when flighting,and the incoming-flow flowing through its leading-edge will generate a expansion-wave above the wing,the supersonic air-fluids flowing through the expansion-wave will rise its dynamic-pressure and lower its static-pressure,then a low-pressure-area will be formed and the lift-force will be generated above the upper-surface of wing.But the flat-plate-wing will form a shock-wave above its leading-edge,the supersonic air-fluids flowing through the shock-wave will rise its static-pressure and lower its dynamic-pressure,the density and temperature of the air-molecule behind the shock-wave will rise obviously,then a high-pressure-area will be formed and the lift-force will be generated under the down-surface of wing.Especially the hypersonic-vehicle/waverider will adopt the attached-shock-wave which is a shock-wave attaching the down-surface of wing,and it will compress the air behind the shock-wav to generate the so-called shock-lift or compression-lift.The shock-wave under the hypersonic flight will be compressed into a very thin layer of high temperature/pressure/density air-molecule-layer.The shock-wave will be closer and closer to the down-surface of wing when the speed of the hypersonic-vehicle will be higher and higher,it will present a phenomenon that the pressure (lift-force) under the down-surface of wing (airframe) will suddenly rise,and it is due to the shock-wave will attach to the down-surface of wing (airframe) then generate a high efficient lift-force (but the air-resistance and the aerodynamic-resistance will have a slight rise along with the increase of flying-speed.),this is equal to taking a flight that riding on the attached-shock-wave.In the same time,the hypersonic incoming-flow will flow through the shock-wave,a large number of its energies will be consumed or converted into heat,then the shock-wave will generate the main aerodynamic-resistance and air-resistance.In addition,the high temperature/pressure/density boundary-layer behind the shock-wave will be converted from laminar-flow to turbulent-flow,then present the abnormality and the high pulsation of the lift-force and heat-transfer-rate.The flight of hypersonic-waverider will feel like to be as gliding over the shock-wave as skiing on the water with the ski,and if it will be flying on the upper-air or the edge-of-space,the missile warhead and the aerospace plane will be diving sharply down a Sine-wave-trough into the atmosphere,and then adopting a high angle-of-attack to get a high lift-force and rise again upon a Sine-wave-peak out of the atmosphere,which is an iterative process of Sine-wave-jumping/gliding flight (Sanger-trajectory),that will feel like to play ducks and drakes on the water with a rotating-oblate-dishing-flake,which will obtain a high maneuverability/efficiency/energy-saving.

3.7 现在航空或气动力控制领域中有很多的利用或主动流动控制和加强机翼上面“附着涡”的方法(“环量控制”)。在一个向上凸起的曲面吹气,气流会沿着圆弧面走一个大弯好像流体粘贴着弯曲表面一样,叫“射流附壁效应(康达效应)”(其实质也属于“涡旋”和其“粘性”的范畴)。利用价值在于当用高速喷气流在凸起曲面吹出这种“附着涡”时,高速流动的涡旋因为粘性可以吸附(剪切、诱导、扰动)更大质量的周围气流一起变向流动,(并可使机翼后缘的附面层增加动能和速度从而推迟分离),而产生“超环量”,当飞机有一定的速度之后其机翼的升力效率会比起用喷气发动机或涵道风扇直接向下喷气的升力效率明显要高(飞机速度越快则吹气的增升效率越高)。如果想要在垂直起飞降落的飞行器上使用吹气增升原理,又要像直升机的旋翼一样在圆周边360度范围产生各向同性的升力,则也有例子是把直升飞行器的升力面做成一个半球形。如图用涵道风扇/螺桨或离心式喷气机向凸起的翼面吹气提高喷气的升力效率,虽然其效率的提高也有限,其外形如同降落伞而提高了失去动力或失速坠落时的安全性,并在一定程度上降低垂直风切变的上升和下击气流影响其升力产生的能力,其最大的缺陷是,如此巨大的迎风面积让其水平前飞的阻力巨大,此半球形机体和表面的射流吹气的流场对于水平风切变和横向风也过于敏感而无法使升力平衡和稳定姿态,所以至今得不到发展。
3.7 There are so many kinds of methods to use,intensify or active-flow-control the attached-vortex of wing (circulation-control) in the aviation and aerodynamic-control fields.When we are blowing on a upward-protruding-convex,the air/fluids will walk along the arc making a long turn,which is like the air/fluids to be sticking the curved surface,that is so called air-jet-theory and wall-attachment-effect (Coanda effect) (and its essence also belong to the domain of vortex and viscosity).The real value is in blowing into this attached-vortex on a upward-protruding-convex with a high-speed-jet-flow,because the viscosity of the fluids will be absorbing (shearing or inducing) a large quantity of the surrounding air-molecules or the boundary-layer to flow away and change direction (and increasing the energy (kinetic-energy and velocity) of the boundary-layer on the wing's trailing-edge and delay the separation of boundary-layer.),then generate the supercirculation.So the lift-force-efficiency of the high-speed-wing will be more higher than that of the jet-engine or ducted-fan which jeting straight downwards (the higher the blowing-lift-enhancement-efficiency,the higher is the speed of aircraft.).If we want to apply the air-jet-theory and wall-attachment-effect on the aircraft of vertical take-off and landing (VTOL) aircraft,and generate the isotropic lift-forces within the 360-degree circle periphery,then there are some aviation-models which lifting-surface has been be replaced by a hemispherical surface.As shown in the figure,for example,we will use the ducted-fan/propeller or the centrifugal-compressor to blow on a upward-protruding-convex,then to rise the lift-force-efficiency which will be very less in fact.It looks like a parachute that will increase the security when it lose power or stall crash,and it will reduce the lift-force-generating influence of the upward and downward airflow under the vertical-wind-shear.Then its bigest drawback will be that its windward area is so large that the air-resistance under horizontal forward flight will be great.The hemispherical airframe and the flow-field with high-speed-jet-flow will be too sensitive to the horizontal wind shear and crosswind that will not balance the lift-force and stabilize its attitude,so far it has not been developed.

3.8 近来磁流体力学(等离子体和离子流)结合空气动力学的领域有些研究,主要在太空飞船返回大气层时有所设想以及在等离子隐身技术上有所研究,但受制于“飞行器全电化”或飞行器的化学能转化为电能的发展迟缓。近年来出现了带有“大气压低温电离装置”(介质阻挡放电(Dielectric-Barrier-Discharge) 和 辉光放电(Glow-Discharge))和“离子风发生器”(电晕放电(Corona-Discharge)和射流低温等离子体放电(Low-Temperature-Plasma-Jet-Discharge)及射频低温等离子体放电(Radio-Frequency-Plasma-Discharge))的技术的大气层内飞行器的气动力部件和推进系统,做成没有旋转部件的“固态发动机/推进器”和气动力控制部件,类似于航天飞船的“离子电推进发动机”和普通飞机的副翼襟翼。例如,其中生成“离子风”(电晕放电(Corona-Discharge))的一种电离装置,其正电极导线的高压电场就会让正极把电子从周围的氮气分子上剥离出来,变成了带正电的离子,又被吸引向着去负电极,在赶去负极的路上,氮离子又会撞上其他氮气分子,把它们变成正离子,就好像“雪崩”一样。正离子在高电压作用下飞向飞机尾部,形成一种离子组成的“风”。但是目前来看,正电极通过这种“离子风”得到的推力很小,即发动机推力小,但是负电极可以做成理想化二维机翼的形式,则“离子风”可以在负电极的机翼上诱导出含有离子流的“涡旋”(“附着涡”),可以提高飞行器的“气动力升力”,是一种可用电场来控制的“离子风涡旋”,成为气动力控制部件。未来更进一步可以加入磁场来控制此“离子风的附着涡和附面层”,提高气动力可控性能。总之,“离子风固态发动机和离子风气动力控制部件”的提出和实践,不但为未来的“飞行器全电化”的发展提供了信心,更是让离子流和磁流体参与空气动力学领域做出范例,为不远的未来“磁流体空气动力学(或电磁空气动力学)”的出现做了铺设。
3.8 Currently,there are some studies in the field of combining the aerodynamics and magneto-hydrodynamics (MHD) (plasma and ion-flow),it is mainly conceived to apply on the spacecraft returning to the atmosphere and the technologies of plasma-stealth.But it is limited by the delayed development of the all-electrification of aircraft or the conversion of chemical to electrical energy.In recent years,there have been presenting some aerodynamic-components and propulsion-systems with the technologies of low-temperature-ionization-device at atmospheric pressure in air (Dielectric-Barrier-Discharge and Glow-Discharge) and the technologies of ionic-wind-generator (Corona-Discharge,Low-Temperature-Plasma-Jet-Discharge,and Radio-Frequency-Plasma-Discharge),that to make it into a kind of solid-state-engine/thruster (without the rotating-components) or the aerodynamic-control-unit,which are like the ion-electric-thrusters of the spacecrafts or the ailerons and flaps on the airplanes.For instance,one of the ionization-device generating the ionic-winds (Corona-Discharge),the high-voltage-electric-field of its positive-electrode-wire will strip the electron from the nitrogen-molecule around its positive-electrode,which will become a positively-charged-atom (positive-ions) and be attracted towards the negative-electrode.When it is running towards the negative-electrode,it will dash against the other nitrogen-molecules and convert them into positively-charged-atoms (positive-ions).Then it is the same as the avalanche.The positive-ions will be flying towards the aircraft's tail under the high-voltage-electric-field,and becomming a blast of ionic-wind.But at present,the thrust that the positive-electrode-wire getting will be very small (the engine's thrust will be too small),but the negative-electrode will be made into the ideal two-dimensional-wing,then the ionic-wind will induce a kind of vortex (attached-vortex) with the ion-flow on the negative-electrode-wing,which will increase the aerodynamic-lift-force of the aircraft.And that is also a ionic-wind-vortex under the control of the high-voltage-electric-field,and becomming a aerodynamic-control-unit.In the future we will add the magnetic-field to contral this ionic-windy attached-vortex/boundary-layer and rise its aerodynamic-controllability.In brief,because the proposals of the ionic-wind-solid-state-engine/thruster and the ionic-wind-aerodynamic-control-unit have been offered and the experiments have been done,it will not only provide confidences in the all-electrification of aircraft,but also let the ion-flow and magneto-fluids combine in the field of the aerodynamics as a successful example,and it will pave the way to the present of the magneto-fluid-aerodynamics (or the electromagnetic-aerodynamics) in the near future.

3.9 对机翼进行“环量控制或主动流动控制”,以及产生和控制机翼上的涡旋,一直是空气动力学的发展方向,当与高超声速飞行、飞船再入大气层和等离子体隐身相关的“磁流体空气动力学(或电磁空气动力学)”正在出现时,终于有可能构思和创造出一种部分甚至完全电离化的“磁流体涡旋(离子流涡旋或离子风涡旋)”,并可以用电场和磁场进行更好控制。那么,这里描述了一种最适合低速及垂直起降飞行的“电磁场控制的磁流体涡旋(离子流涡旋或离子风涡旋)”,构形上看是一种“特异性二三维结合环形分离涡”(“奇异涡环”),这将是人工创造出的“第三大类涡旋”。其是以自然界中唯二的两大类形态或体系的“涡旋”(分别是“二维的旋涡”和“三维的涡环”)有机结合而成,可看作为台风/飓风和空中的烟圈的结合体,由电离化的空气射流在电磁场的约束和控制下“自组织”构成的整个涡旋,而且其流动是完全处于一个复杂有序的强大电磁场的控制之下的。而最可取之处在于其有巨大的增加升力、效率、安全、强壮和可控性的潜力,用于垂直起降飞行器最佳。唯一需重视的缺点就是电离空气的耗能高。首先,我们地球人第一次设计在一个水平放置的相对规整(可以是多边形最好是圆形)的薄平板(边缘也没有上翘或下弯)上实现空气动力学的升力涡旋,当然我们更可以在一个圆锥面或球面上产生这种涡旋和升力,更进一步还得考虑“附面层”流体运动才有可能得到“气动力升力”,这是空气动力学和流体力学方面的一种全新思路。如果我们用射流吹气制造的“附着涡”、“分离涡”、“脱体涡”等,想要在一个机翼上表面产生“气动力升力”,则必须有两个关键,一个是涡旋所形成的“涡核”内的低压强可以很好的传导到“附面层或边界层”流体中,另一个是要在机翼后缘形成“下洗流”(前方来流的“动量的变化量”的垂直向下方的分量)。那么,在此我们可以电离空气制造离子射流,用电磁场约束控制这些离子射流,在一个水平放置的圆盘面上构成一个“特异性二三维结合环形分离涡”(“奇异涡环”),其不但可以形成典型的两种不同的“涡核”,更可以吸附(剪切、诱导、扰动、渗混)大量的周围空气(都被电离以后)在圆盘面的尾部边缘形成“下洗流”。这种“奇异涡环”的两种不同的“涡核”,分别类似于“台风中心的涡核”(“第二涡核”)和“烟圈内部的涡核”(“第一涡核”)。而正是这个“第二涡核”的存在,为大幅度增加升力和效率提供了无限可能。这种“特异性二三维结合环形分离涡”(“奇异涡环”)是大自然中不可能天然存在的(包括太阳或各大气态行星上都不可能存在),是第一次在地球人的空气动力学(流体力学)中创造出来的完美对象。
3.9 The research of circulation-control or active-flow-control about the wing and the generation/control of the vortex on the wing which always the developing direction of the aerodynamics.When the magneto-fluid-aerodynamics (or the electromagnetic-aerodynamics) relating to the hypersonic-flight,spacecraft reentry into the atmosphere,and the technologies of plasma-stealth are developing,we will conceive and create a partly/wholly-ionized magneto-fluid-vortex (ion-flow-vortex or ion-flow-vortex),and will be more controllable in the electric-field and the magnetic-field.So we will describe a electric-field/magnetic-field controlling magneto-fluid-vortex which is the best fit for low-speed flight and for vertical take-off and land (VTOL),and it will be looked as a kind of specific two-dimensional and three-dimensional combined annular-separation-vortex (singular-vortex-ring) on its structure,and it will be the artificially-created third-broad-categories of vortexes.And it will be made combining the two forms(two-broad-categories) of vortexes (one form of two-dimensional-vortex and another form of three-dimensional-vortex) in the nature,which will be looked as a combination of hurricane/typhoon and smoke-ring,and this vortex will be made up of the ionized air-jet under the control of magnetic-field due to the self-organization.Its flow-motion will be under the control of a complex and orderly strong-magnetic-field,the most important merit of it will has the great potential of increasing the lift-force,efficiency,safety,strength and controllability.And it will be most suitable for the vertical take-off and land (VTOL) aircraft,but its sole drawback will be the much too high electric-energy-consumption when ionizing the air.In the first place,we will construct a lift-force-vortex on a relatively regular flat (polygon/circle-plate,and the edge has not been upturned or recurved).We will also construct this vortex on the circular-cone-surface or hemispherical-surface,but we must consider the flow-motion of the boundary-layer and make it possible for us to get the aerodynamic-lift-force.This is a new thinking in Aerodynamics and Hydrodynamics.If we use the air-jet-blowing to construct the attached-vortex,separated-vortex,detached-vortex above the wing,and want to generate the aerodynamic-lift-force,there are two keys: one thing will be that the low-air-pressure of the vortex-core will be conducted into the boundary-layer fluids;the other thing will be that the downwash-flow will be formed around the trailing-edge of wing (the vertical-downward-component of momentum-variation about the incoming-flow.).So we will ionize the air and generate the ion-jets,then we will use the magnetic-field to constraint and control these ion-jets,and to construct this specific two-dimensional and three-dimensional combined annular-separation-vortex (singular-vortex-ring) on a horizontally-placed-disc-surface.Then it not only will form two kinds of typical vortex-cores,but also will be absorbing (shearing or inducing) a large quantity of the surrounding air-molecules to form the downwash-flow around the trailing/outside-edge of disc-surface.These two kinds of vortex-cores about the singular-vortex-ring,which are respectively similar to the vortex-core of hurricane/typhoon-center (the second vortex-core) and the vortex-core of smoke-ring-internal (the first vortex-core).But just because of the existence of the second vortex-core,that make it limitlessly possible to effectively enhance the lift-force and efficiency.This specific two-dimensional and three-dimensional combined annular-separation-vortex (singular-vortex-ring) willnot be existence in nature (on Sun,and all gaseous-planets.),and it will be a perfect object create be human-being in the earthman's aerodynamics or hydrodynamics for the first time.

3.10 空气动力学发展到高超声速阶段和飞行器隐身性的需要,必然推动空气电离化(低温电离)和主动流动控制技术的广泛应用。我们先在这个圆盘升力面内构造一个磁场,并通过内部的电离和加速的装置把空气电离后,再将一定速度的离子流从圆盘表面的喷嘴处贴着表面沿圆周切向有序的喷射而出(喷嘴可以很多并有序分布),电离流体(正负不同电荷的流体喷射的方向相反)在圆盘内的磁场中受到约束并逐渐改变方向,最终形成我们所预期的“特异性二三维结合环形分离涡”(“奇异涡环”),但是“第一涡核”及“第二涡核”的产生过程都有自组织的特征(甚至最后还会在圆盘尾部边缘形成“下洗流”)。其中,在圆盘的圆心处还装设有大功率的电子枪和激光向上照射,可以把圆心处的“第二涡核”所要吸附的上部空气更充分的电离。又比如,这里有两个磁场(一种是“固定磁场”另一种是“可旋转磁场”),都由“超导磁棒束”来构造,在圆盘上由圆中心向外360度辐射性均匀分布的磁棒束所构成的是“固定磁场”,而在圆盘的中心由一圈垂直竖立的磁棒束是可以高速旋转的,其所构成的是一个“可旋转磁场”,正是圆盘中心这个可旋转磁场在高速旋转时可大大增加“第二涡核”吸附上方电离空气的质量从而增加升力和效率(比如可以在飞行器垂直起降或悬停时,将“第二涡核”的高度大幅度增高,并提高圆盘中心的“可旋转磁场”的强度和旋转速度,及提高电离空气的激光和电子枪的功率,而主动吸入更大质量的上方电离空气)。
3.10 Beacause of the pressing need in the stage of development about the hypersonic-flight and the technologies of plasma-stealth,it must promote the wide application about the technologies of air-ionization (low-temperature-ionization) and active-flow-control.We will construct a magnetic-field on this disc-surface first of all,then ionize the air through the internal ionizing/accelerating-device,and spout a certain speed ion-flow towards circumferential-tangential-direction from the ion-jet-nozzle above the disc-surface-edge (the ion-jet-nozzle's number will be great and be orderly distributed.),so the ionizing fluids (the jet-flow-directions of the positive/negative-charge-fluids will be contrary.) will be magnetically-confined in the magnetic-field on this disc-surface,and gradually change itself directions,and construct the specific two-dimensional and three-dimensional combined annular-separation-vortex (singular-vortex-ring) which we have expected in the end,but the generating-processes of the first vortex-core and the second vortex-core will have a self-organization feature (even there will be a downwash-flow being formed around the trailing/outside-edge of disc-surface in the end.).Among them,there will be some high-power electron-guns/laser-devices in the center of the disc-surface which will irradiate upwards,and will ionize a large number of absorbed-air above the second vortex-core at the center of the disc-surface.for example,there are two kinds of magnetic-fields (one kind is the fixed-magnetic-field,and another kind is the rotating-magnetic-field.) which will be made of the superconducting-magnetic-rod-beams.The fixed-magnetic-field will be made up of the superconducting-magnetic-rod-beams which will be uniform distributed from the center to the outside of the disc-surface with 360-degree-angle,and the rotating-magnetic-field will be made up of the superconducting-magnetic-rod-beams which is vertically circular erected and will be rotating at high speed aroud the center of the disc-surface.Just because this rotating-magnetic-field will be rotating at high speed,and which will greatly increase the number/mass of upper-ionized-air absorbed by the second vortex-core,and effectively enhance the lift-force and efficiency (for instance,when our aircraft will be in the state of vertical-take-off-and-land( VTOL) or hover,we will greatly increase the height of the second vortex-core and the strength-and-rotating speed of the rotating-magnetic-field,and enhance the power of the electron-guns/laser-devices which ionizing the upper-air,so it will proactively absorb the greater number/mass of upper-ionized-air.)

3.11 我们在图示描述了两种磁场(“固定磁场”和“可旋转磁场”)的构造及其与电离流体的相互作用,我们是从圆盘内用“正离子喷口”沿着圆周切向喷出已经电离的空气射流的,电离的正离子流体就开始切割固定磁场而受“洛伦兹力”向圆盘中心改变流动方向,在横切面上看,正离子流在磁场中的加速(改变方向),是一个从圆盘的外边缘表面底部——向圆盘中心——再向中心上方——再向外上方——再向外下方——回到圆盘外边缘,然后是一个不断迭代回旋的过程,正离子受磁场的洛伦兹力经过一个螺旋线形的压缩和加速过程,最后形成了“第一涡核”。但实际上,在这个“第一涡核”的形成之前,从圆盘边缘向中心流动的电离流体会先一步受挤压加速形成了更强更明显的“第二涡核”,然后是由“第二涡核”的流体再向外翻转(分离)而形成的“第一涡核”。而“升力”的产生过程,主要可以看作是由圆盘中心的“第二涡核”从上方“吸附(剪切、诱导、扰动、渗混)”大量空气,再混入整个涡旋中得到两个涡核所传导来的动能和速度(“涡量”和动量),最后在圆盘的边缘形成“下洗流”。一般来说,出于节省能源的目的,“下洗流”最后离开圆盘升力面的边缘时候,都已经还原为空气分子流(不再处于电离态),但是因为用磁场来偏转离子流的不完全性,所以“下洗流”还多少带一点“旋转性质”(而非垂直向下方流动),这算是一种“诱导阻力”吧。图中已另外给出了电磁学“左手定则”的图示,有助于理解正离子流在磁场中运动受“洛伦兹力”而改变方向最终形成两个“涡核”的过程。
3.11 In the illustration,we have described the construction of two kinds of magnetic-fields (one kind is the fixed-magnetic-field,and another kind is the rotating-magnetic-field.),and the interaction between them.We will spout a certain speed ion-flow towards circumferential-tangential-direction from the positive-ion-jet-nozzle above the disc-surface-edge,so the ionizing fluids will be magnetically-confined by lorentz-force in the magnetic-field on this disc-surface,and gradually change itself directions.Looking at the cross-section,the positive-ion-flow in the magnetic-field will be a process which is changing itself speed from the trailing/outside-edge of disc-surface towards the center of disc-surface,towards above the center,towards above the outside,towards beneath the outside,and return to the trailing/outside-edge of disc-surface in the end.And this will be a process of continuous iteration and convolution.In the process,the positive-ion-flow magnetically-confined by lorentz-force will be helically compressed,accelerated,and changed itself directions,and finally form the first vortex-core.But before the generation of the first vortex-core,the positive-ion-flow which flowing from the trailing/outside-edge of disc-surface towards the center of disc-surface will have to form a stronger second vortex-core under compressing and accelerating,then the fluids of the second vortex-core will be turned outwards (be separated) and form the first vortex-core.The generating-process of the aerodynamic-lift will be looked like that this second vortex-core be absorbing (shearing or inducing) a large quantity of the surrounding air-molecules to form the downwash-flow around the trailing/outside-edge of disc-surface,into which this two kinds of vortex-cores will transmit the kinetic-energy and velocity (momentum and vorticity).Generally speaking,for the purpose of energy-savings,when the downwash-flow leave around the trailing/outside-edge of disc-surface that its fluids have been returned to the air-molecules (no longer in the ionized state).But because of the magnetic-field-deflecting incompleteness of the ion-flow,so the downwash-flow will have some rotating-properties (rather than flowing straight downward.),which will be looked as a kind of induced-drag.There have been presented the Left_hand Rule in Electromagnetics in the illustration,which will help to understand the process of the generation about this two kinds of the vortex-cores.

3.12 高速的离子喷流分别从正、负离子喷口喷出,要在一个上述特定的圆盘形机体表面“固定磁场”约束下,形成这个圆盘上的这种“特异性二三维结合环形分离涡”(“奇异涡环”),有几个阶段的流动形式。最开始是离子流受到指向圆心的“洛伦兹力”而相互剪切挤压向中心,形成一个类似水漩涡的“平面旋涡”,接着离子流体在其中心处向上堆挤升起形成类似飓风/台风的中心的涡核(“第二涡核”),这是一个“二维涡旋和中心涡管”,并一边受“洛伦兹力”而向外翻卷和收缩,不断重复迭代这个过程,最后形成了类似烟圈的涡核(“第一涡核”),这是一个“三维的涡环”。而所谓的“涡量”大部分就集中在这两个不同的“涡核”的流体里。其中的“第二涡核”(中心涡管)可以人为的堆起得很高大,并且增加中心的“旋转磁场”的转速,可以大幅度增加吸附上部的电离空气的量和提高“磁流体的粘性”,主要是为了航空飞行器在低速飞行或直升起降悬停时提高升力和效率。注意,这种“升力涡旋”的“涡量”都来自于初始的正负离子喷流(完全电离)的动能和动量,但是完全电离的离子喷流的质量密度仍然比较低,所以要求其速度很大才能得到升力所需的“涡量”(动量),所以对于碟形飞行器来说,其产生升力所消耗的能量(初始正负离子喷流的动能加上电离的耗能)是远大于现代的旋翼直升机的耗能的,但是却得到了无可比拟的空气动力学特性(高度的可控性、适用性、通用性、安全性,以及升力强度和效率的宽范围可调性等等)。
3.12 The high-speed ion-flow will be spouted out from the positive/negative-ion-jet-nozzles,and be magnetically-confined in the fixed-magnetic-field on this disc-surface,and construct the specific two-dimensional and three-dimensional combined annular-separation-vortex (singular-vortex-ring),which have several phases of flowing.In the beginning the ion-flow will be sheared and compressed by the lorentz-force towards the center,and form a likeness of water-eddy (planar-vortex),then it squeeze up the heap to form a likeness of vortex-core of hurricane/typhoon-center (the second vortex-core) which is a two-dimensional-vortex or center-vortex-tube,then be turned outwards (be separated) and be compressed towards the center by the lorentz-force,and by this process of continuous iteration and convolution,then form a likeness of the vortex-core of smoke-ring-internal (the first vortex-core) which is a three-dimensional-vortex.And the so-called vorticity will be mostly concentrated upon these two kinds of vortex-cores.Among them,the second vortex-core (center-vortex-tube) will be heaped up very high,and increase the rotating-speed of the rotating-magnetic-field at the center,then be increasing the viscosity of magneto-fluids and the absorbed number/mass of upper-ionized-airs,which be in order to greatly enhance the lift-force and efficiency when aircraft in the state of vertical-take-off-and-land (VTOL) or hover or low-speed-flying.Please note that the vorticity of this vortex-about-lift (the lift-vortex) will come from the initial kinetic-energy and momentum of high-speed positive/negative-ion-flow (wholly-ionized),but the mass-density of the wholly-ionized ion-flow will be very low,so it require the initial speed of the ion-flow be very high and to get the enough vorticity (momentum) the lift-force needed.So for the saucer-shaped spacecraft,the energies (initial kinetic-energy plus ionizing-energy of the ion-flow) consumed by generating the lift-force will be more larger than that of the modern-helicopter,but obtain the incomparable Aerodynamic characteristics (include the high ontrollability,applicability,generality,security,adjustability of lift-strength and efficiency at a wide range.)

3.13 虽然我们可以直接将上述这种“特异性二三维结合环形分离涡”(“奇异涡环”)用于现代的飞机机体表面产生“气动升力”,因为我们更多时候是采用了“低温电离方式”(喷射高速负电子流碰撞上方空气分子),而其整个涡旋流体的平均温度不高,所以一般情况下可以在机表蒙皮下用普通的“冷却剂循环系统”即可冷却蒙皮。但考虑到未来在太空飞行战斗时,碟形飞行器的战场主要是在太阳和各大行星的大气层内。所以碟形飞行器的“升力涡旋”的电离流体的温度要大幅度提高,得采用“高温电离方式”(比如“电弧电离”)才能更好的用更强的磁场控制流体以对抗各种强大的风暴,这会让最贴近机体表面蒙皮的“附面层”(边界层)流体的温度也很高(因对流现象),导致出现对机表蒙皮的冷却困难。所以这里采用了“开放式等离子体环流发生器”,分别处于机体的上顶部和下底部圆心周围,其产生一种类似于“核聚变托卡马克装置”的“等离子体环流”(光环)(含有强大的感生电流),并可以将其放出装置让其在离心力作用和稳定减弱的磁场约束下一个接一个地自由扩张和释放出去,但是此光环在机体表面仍然被一个均匀的“机体表面固定磁场”所约束,并在圆盘外边缘处自动破裂(现代的核聚变装置中的等离子体环流的存在时间已经超过数分钟,但是现在的困难是如何让此“光环”在大气压下的空气中保持一定时间)。其破裂后的电离流体再在机体表面的“固定磁场”约束下形成碟形飞行器的“奇异涡环”。上述的这种“可开放的等离子体环流发生器”在现代科学中已经有数十年的设计历史了,其主要是用于武器系统的研究,作为一种“防御性磁流体武器”,比如很多设计中是将其产生的“等离子体环流”(光环)(含有强大的感生电流)放出装置,并进行压缩和加速后喷射而出,其内的高压缩性的电磁能量可以在近距离爆炸击毁来袭导弹。但是,这里我们只是将“等离子体环流”(光环)用来把碟形飞行器上面的“升力涡旋”与其“附面层”(边界层)流体相互隔离,(当然其中这种“光环”因为含有强大的感生电流也在太空战斗时作为一种装甲),一圈圈一层层的这种“等离子体环流”(光环)是高度压缩性和有大电流和强磁场的,所以可以说具有在磁场中高度“硬化或固化”的特性,可以看成一个“磁场悬挂着的板块”,即碟形飞行器的机体相当于用磁场悬挂在这个板块下方,所以机体表面蒙皮的附面层(边界层)流体可以非常厚,甚至于碟形飞行器的升力可基本不受到其附面层(边界层)的流体厚度和流动情况的影响了(不管是层流或湍流),这样我们就可以在附面层流体中注入低温的“液氮”(或“液氦”)而冷却体表蒙皮,而大幅度减少上部高温流体对机体的直接导热,从而让碟形飞行器可以在极高温度的太阳上和极低温的气态行星上长时间飞行了,飞行器上面的“升力涡旋”是在强磁场的控制之下可以对抗高速风暴流体的吹袭,更不要说“等离子体环流”(光环)(含有强大的感生电流)作为一种装甲可以对抗太阳的“百万倍电磁风暴”和气态行星上的“气液固三相流体风暴”的射流和固体的高速撞击。也不用说这种完全电离化和电磁控制的“升力涡旋”产生的“升力”可轻易克服太阳上的巨大引力了。
3.13 Although we will use the specific two-dimensional and three-dimensional combined annular-separation-vortex (singular-vortex-ring) on the surface of modern-aircraft to get the lift-force,because we will usually use the way of low-temperature-ionization (to spout the high-speed-negative-ion-flow colliding the upper-air-molecule.),then the average fluids-temperature of the vortex willnot be very high,so the we will use the ordinary coolant-circulating-system cooling the skin of the lift-force-surface.But considering the saucer-shaped spacecraft will often be flying in the atmosphere of sun/gasous-planets in the future,the average fluids-temperature of the vortex will have to be greatly increased by using the way of the high-temperature-ionization (for example the arc-discharge-ionization.),and only then will resist all sorts of powerful storms by means of stronger magnetic-field better-controlling the fluids of vortex,and this will also increase the temperature of the boundary-layer which most close to the skin of the lift-force-surface (because of the Thermal-Convection-Effect ),then cause the cooling-difficulty of the airframe-skin.So we will fit an openable plasma-circumfluence generator in the top and bottom of the saucer-shaped spacecraft,which is same as the tokamak-device,and will creat the same kind of plasma-circumfluence (a ring of light) which have a strong induced-electric-current/magnetic.And this plasma-circumfluence (a ring of light) will be freely released out of the generator under the actions of the centrifugal force and a weakening magnetic-field one after another.But this plasma-circumfluence(a ring of light) will also be steadily constrained by a symmetrical fixed-magnetic-field of the airframe's surface,till it be broken by self at the outer margin of airframe (the plasma-circulation of modern tokamak-devices will be kept several minutes,but the new difficult will be how this ring of light will keep for some time in the air under one bar pressure.).The ion-flow after the break will form the singular-vortex-ring which constrained by a symmetrical fixed-magnetic-field of the airframe's surface.The ideational history of above-mentioned openable plasma-circumfluence generator has lasted for decades,and it often be used in the study of weapon,and as a kind of defensive magnetic-fluid weapon.For instance,there are many weapon'design which will release this plasma-circumfluence (a ring of light)(which has a strong induced-electric-current) out of the generator,and will be recompressed and reaccelerated,and then spout it as a shell/bomb to destroy incoming missile with the hypercompressive electromagnetic-energy.But here we will only use this plasma-circumfluence (a ring of light) as a isolation layer between the vortex-about-lift (the lift-vortex)on the saucer-shaped spacecraft and the fluids of boundary-layer (meanwhile,this ring of light will be used as a new kind of armor (magnetic-fluid-armor) due to possessing a strong induced-electric-current.).Circle by circle,layer by layer,this plasma-circumfluence (a ring of light) will be looked as a plate suspended in the magnetic-field which have a highly hardening/solidifying characteristic due to possessing strong induced-electric-current,strong magnetic-field,high compressibility.Then it will be looked as that the airframe of saucer-shaped spacecraft be suspended under this plate in the magnetic-field.So the fluids of boundary-layer on the airframe's skin will be far more thicker than usual,even the lift-force of the saucer-shaped spacecraft willnot be effected by the thickness and motion of the fluids in the boundary-layer (whether it be laminar-flow or turbulent-flow.).Then we will spout the liquid nitrogen/helium to cool the boundary layer and the airframe's skin,so substantially lower thermal-conducting from the upper-high-temperature-fluids to the airframe's skin.So the saucer-shaped spacecraft will be flying on the extremely-high-tempreture sun and all the badly-cold gaseous-planets for a long time.And the vortex-about-lift (the lift-vortex)on the saucer-shaped spacecraft will not only resist the striking of ordinary storm under the contral of the strong magnetic-field,but also this plasma-circumfluence(a ring of light) will resist the solar-storm which be more than the million times energy of earth's giant storm (hurricane/typhoon) as a kind of armor with a strong induced-electric-current,and resist the impact and disturbance of the flowing three-phase-fluids(gas,liquid and solid) storm on all the badly-cold gaseous-planets.Needless to say the lift-force generated by this vortex-about-lift (the lift-vortex) will be able to overcome the great sun's gravity under wholly-ionizing and electric-field/magnetic-field controlling.

3.14 根据“动量定理”和“牛顿第三运动定律”,空气动力学的涡旋在机翼上产生升力,必须对来流向下方“吸附(剪切,诱导)”(下洗作用),形成“下洗流”,其在垂直方向的动量的分量就是升力。但是不管是机翼、风扇、螺旋桨等,都在翼尖处形成“翼尖涡”,有强烈的旋转性质。其实在碟形飞行器的“升力涡旋”形成的“下洗流”也保留有一定的“旋转性质”,这是用磁场“洛伦兹力”偏转离子流方向时不可避免的一种能量浪费。这会在历史上的“碟形飞行器目击案例”中出现一些不同的机体下部的空气动力学现象,比如碟形飞行器下部在城市郊区或沙漠的地面悬停时会出现明显的“尘卷风”(风力较弱),而碟形飞行器在水面低速飞行或悬停时会出现“水龙卷”等,前者是常见的典型现象即形成的“下洗流”是向外自由扩散的旋转风,后者是当碟形飞行器的机体下部的“下洗流”仍然保留有相当的电离程度时,机体下部的磁场会将“下洗流”向内吸引收缩形成风力比较强烈和窄小的柱状旋转风,其内的“管状流动低压区”可以把海水等变成水蒸汽而向上倒吸作用,也可以把人体向上平稳吸离地面而不旋转或伤害人体。碟形飞行器在超声速及高超声速飞行时,产生“气动升力”的情况要更复杂一些,其在低超声速时,可以同时由机体上部的“奇异涡环”产生“负压的升力”和机体下部的“旋转性质的下洗流”与来流之间的压缩而生成的激波来产生“正压的升力”;但是随着飞行速度的增加,其机体上部的“奇异涡环”的“第二涡核”的高度会逐渐降低并减少产生“负压的升力”,而更多是由机体下部的“旋转性质的下洗流”与来流之间的压缩而生成的激波来产生“正压的升力”;甚至在高空的高超声速飞行时其气动升力,可以完全由机体下部比较平坦的表面与来流之间产生的“激波升力”(压缩升力)来提供,但是机体的“飞行纵轴”与前方来流之间的“相对迎角”将会一直保持甚至会增大。而机体下部比较平坦将有利于把“旋转性质的下洗流”用磁场收缩后,与来流在下部的“激波”后的流体相互压缩作用,形成以下表面360度角的比较均匀的“正压的升力”,所以碟形飞行器机体下部一般都比机体上部更平坦,这是为了在超声/高超声速时和适当的“飞行迎角”条件下,更好地用“激波”和“下洗流”形成“下表面的升力”。比如在唯一的碟形飞行器的两倍声速飞行的照片中,当其机体表面的附面层(边界层)和蒙皮采用“液氮/氦”来进行冷却(一种飞行器的视觉遮掩及红外隐身技术)时,则的机体上部的“第二涡核”因为被超声速来流强力吹袭而向后倾斜拖曳,则此涡核内会出现“回流流体团”(旋转性气团)的现象,而其机体下部则会因为“旋转性质的下洗流”被来流压缩而成为倾斜向后的扁管形流体,并在此扁管内有“倒吸流”现象(比如下部机体表面的液氮/氦形成的雾气中出现动态凹陷现象)。但是在高速飞行时,不管是上部的“奇异涡旋”还是下部的“旋转性质的下洗流”都仍然处于电离态,所以在白天的阳光下仍然不可见,一般只是见到碟形飞行器表面的用于冷却附面层的液氮/氦雾气,只有在黑夜里才可见到电离流体在磁场中运动时发光现象。
3.14 According to the Momentum-theorem and Newton's Third Law of Motion,if aerodynamic-vortex want to generate the lift-force on wing,it will must absorb (shear or induce) the incoming-flow downwards (downwash-tendency),and form the downwash-flow,then the vertical-direction-component of the downwash-flow's momentum will be the lift-force.But this downwash-flow behind the wingtips of the wings,fans,and airscrews will never avoid generating the trailing-vortex (wake-vortex) in which the fluids be posessing a violent rotating-characteristic.And this is an inevitable energy-waste as a result of the lorentz-force of magnetic-field has deflected the direction of the ion-flow.This have left many different Aerodynamic-phenomenon about the witness-case of saucer-shaped spacecraft in history.For example,the saucer-shaped spacecraft will generate an obvious dust-devil beneath its airframe when it hovering on the ground of the city suburbs or the deserts,and it will generate an obvious waterspout beneath its airframe when it hovering or low-speed-flying on the sea-surface.The former will be a typical phenomenon that the downwash-flow be a rotating-wind diffusing outwards.The latter will be a rare phenomenon that the downwash-flow be kept ionizing-state and be contracted inwards by the under-magnetic-field to form a stronger/narrower columnar-rotating-wind,and the tubular-flowing-low-pressure-area in it will suck-back the water-vapour converting from sea-water upwards,and the tubular-lowing-pressure-area will also steadily suck the human-body upwards to leave the ground but not hurt or rotate the body.The aerodynamic-lift-force-generating under the supersonic and hypersonic flight about the saucer-shaped spacecraft that will be more complex,and its upper-surface-lift-force about negative-air-pressure will be supplied by the singular-vortex-ring,and its down-surface-lift-force about positive-air-pressure will be supplied by the shock-wave generating from the compressing between the incoming-flow and the rotating-characteristic downwash-flow.But with the increasing of the flying-speed,the height of the second vortex-core will decrease gradually and reduce its upper-surface-lift-force,and more of down-surface-lift-force.Even under hypersonic flight,its aerodynamic-lift-force will be wholly generated by its down-surface-lift-force about positive-air-pressure of the shock-wave (the so-called shock-lift or compression-lift),but the relatively angle-of-attack between the incoming-flow and its longitudinal-axis in flying will be kept and even increased.And the down-surface-airframe will always be relatively flat,that it will use the lorentz-force of magnetic-field to shrink the rotating-characteristic downwash-flow inwards,and then compress with the incoming-flow behind the shock-wave,to form the relatively uniform positive-air-pressure about down-surface-lift-force on the down-surface-airframe at 360 degree angle.It is so often that the down-surface-airframe will be more flater than the upper-surface-airframe about the saucer-shaped spacecraft,then it will better use the shock-wave and the downwash-flow to form the down-surface-lift-force which be under the supersonic and hypersonic flight and the relatively angle-of-attack.For instance,in the only photo of flying at twice the speed of sound about the saucer-shaped spacecraft,that the boundary-layer and the airframe'skin will be cooled by the liquid nitrogen/helium (a kind of visual-concealed and infrared-stealth technology of aircraft.),then the second vortex-core will be dragged and tilted backwards by the blowing of supersonic incoming-flow,and there will be some back-flow fluid-mass (rotating-characteristic air-mass) appearing in this second vortex-core,but the rotating-characteristic downwash-flow under the airframe will be compressed by the incoming-flow and form a backward-inclined flat-tube-shaped-fluids,and there will be some inverted-sucting-fluids phenomenon in this flat-tube-shaped-fluids (for example,there will be an obviously transient-dimple-phenomenon in the liquid nitrogen/helium fog under the airframe.).But under high-speed flight,whether the singular-vortex-ring or the rotating-characteristic downwash-flow will always be ionized,so they willnot be visible under the sunlight,so it will usually be watched the liquid nitrogen/helium fog on the saucer-shaped spacecraft's airframe,and only in the dark of night will it be observed the luminescence-phenomenon when the lorentz-force of magnetic-field deflecting the direction of the ion-flow.
