Reflexed trailing edge
Webthe leading edge. A reflexed camber line was designed to produce zero pitching moment, but has generally not been used. These foils were derived to get good high lift with ... geometry near the trailing edge, while maintaining the same general properties as the 6-series foils. The camber line can be described by a simple WebA mean camber line with a reflexed trailing edge must have a point of inflection, and, therefore the simplest equation that can describe it as a cubic. Four boundary conditions …

Webconsiderations, and in this case the trailing edge and leading edge angles must be explicitly constrained as well. The following constraints have been found suitable for this problem after a number of optimization attempts. CL = 1.25 θ TE = 6.25 (t/c)0.33c = 0.128 CM = −0.133 θ LE = 180 (t/c)0.90c = 0.014 (6)
WebMar 21, 2005 · We have to go fairly far above the wing at the trailing edge where the flow isn't going up. That would argue that the downwash isn't effecting the wing any more in the area of the reflexed ailerons which is the reason the cp moves forward. So most of the lift on the wing is pretty far forward where the downwash velocity is minimal.
