A straight, or moderate sweep, wing may experience, depending on its airfoil section, a leading-edge stall and loss of lift, as a result of flow separation at the leading edge [4] and a non-lifting wake over the top of the wing. However, on a highly-swept wing leading-edge separation still occurs but instead creates a vortex sheet that rolls up ...
A lifting canard generates an upload, in contrast to a conventional aft-tail which sometimes generates negative lift that must be counteracted by extra lift on the main wing. As the canard lift adds to the overall lift capability of the aircraft, this may appear to favour the canard layout. In particular, at takeoff the wing is most heavily ...
The list excludes helicopters, including compound helicopters and gyrocopters, because they are assumed to have this capability. For more detail on subtypes of VTOL, see List of tiltrotor aircraft . This is a dynamic list and may never be able to satisfy particular standards for completeness.
Longitudinal dihedral can also mean the angle between the zero-lift axis of the wing and the zero-lift axis of the horizontal tail instead of between the root chords of the two surfaces. This is the more meaningful usage because the directions of zero-lift are pertinent to trim and stability while the directions of the root chords are not.

Powerboat sales rose 18% in September, marking the third consecutive month of double-digit gains. This is great news for the boating industry and boating stocks. On the back of these tailwinds, it ...
VTOL disc loading lift efficiency. The tiltwing design offers certain advantages in vertical flight relative to a tiltrotor. Because the slipstream from the rotor strikes the wing on its smallest dimension, the tiltwing is able to apply more of its engine power to lifting the aircraft.
Wings to get: Sweet Heat and Arizona Given the many other things you could eat during your time in New Orleans, chicken wings seem as if they should be pretty low on the list. But Wing Snack and ...
