In this chapter we discuss the aerodynamics of swept wings in transonic flow. To demonstrate the merits of swept-back wings, simple sweep theory is presented. It is shown why a swept wing can experience local supersonic flow while still being in subcritical conditions, thereby postponing the ...
swept wing adj. 有后掠翼的(飞机) wing collar n. (衬衫的)翼领,燕子领 wing tips n. 布洛格鞋 鞋头有一块打孔的皮片,向两侧延伸,从上面看类似字母W的形状。这种装饰会降低鞋的正式程度。 swing wing [空] n. 变后掠机翼;变后掠翼飞机; a. 变后掠机翼的 最新单词 helical eyepiece的中文释义 螺...
Vortices are one of the many phenomena associated to the study of aerodynamics. The equations of aerodynamics show that the vortex is created by the difference in pressure between the upper and lower surface of the wing. At the end of the wing, the lower surface effectively tries to 'reach ...
The same authors have then used the theory of thin walled beams to investigate the subcritical aeroelastic response of swept anisotropic wing structures (Librescu and Song, 1992). Librescu and Song (2006) and Suresh and Nagaraj (1996) have extended the basic theory for TWBs to include several...
wing is outside Mach cone, component of Mach number normal to leading edge is supersonic → Large Wave Drag If leading edge of swept wing is inside Mach cone, component of Mach number normal to leading edge is subsonic → Reduced Wave Drag For supersonic flight, swept wings reduce wave ...
In the history of aviation, flight speeds have constantly increased due to the development of more powerful engines and the improvement of aerodynamic properties. Especially, the introduction of jet engines and sweptback wings made it possible to approach and even exceed the speed of sound. This ...
- Sweptback Wing – forward and in - Straight Wing – backward and out Stalls in training aircraft What types of airfoils create lift? Ailerons – controls roll Frise – both sides move the same amount up/down as the other Differential – the downward aileron doesn't go as far down as ...
' - well, it's all do to with that old nemesis of RC pilots called the center of gravity. Usually, the CG is measured in relation to the MAC. This is super helpful to know if you're trying to find the CG of a flying wing, tapered wing airplane or swept wing glider....
one of which shoots over the wing as the other dives underneath. People used to think that a simple difference in the speed of the two air streams caused the lift on the wing, but we now know this is wrong. The argument went like this: the upper surface of an airfoil is curved, whi...
