Wing twist is an aerodynamic feature added to aircraft wings to adjust lift distribution along the wing.. Often, the purpose of lift redistribution is to ensure that the wing tip is the last part of the wing surface to stall, for example when executing a roll or steep climb; it involves twisting the wingtip a small amount downwards in relation to the rest of the wing.
Dog tooth on the wing of a Hawker Hunter. A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressing outboard at high angle of attack. [1] The effect is the same as a wing fence. [2]
The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip. This is usually to ensure that at stall speed the wing root stalls before the wing tips , providing the aircraft with continued aileron control and some resistance to spinning .

These videos detail the Active Aeroelastic Wing two-phase NASA-Air Force flight research program to investigate the potential of aerodynamically twisting flexible wings to improve maneuverability of high-performance aircraft at transonic and supersonic speeds, with traditional control surfaces such as ailerons and leading-edge flaps used to ...
Pugachev's Cobra; the nose of the aircraft is pulled up suddenly. The aircraft pitches up to 90–120° angle of attack. The nose then falls back to the horizontal, and the aircraft accelerates away in the original direction ; Kulbit; post-stall maneuver similar to Pugachev's Cobra, but going to 360° pitch angle, flying a "loop"
The X-53 Active Aeroelastic Wing (AAW) development program is a completed American research project that was undertaken jointly by the Air Force Research Laboratory (AFRL), Boeing Phantom Works and NASA's Dryden Flight Research Center, where the technology was flight tested on a modified McDonnell Douglas F/A-18 Hornet.
In the case of the AA-1 the left and right wings were identical, interchangeable and built on a single wing jig, thus the more traditional use of washout in the wing design was not possible. [ 2 ] Stall strips are usually factory-installed but, on rarer occasions, may be an after-market modification.
