Abstract - High lift devices (HLD) are designed to expand the flight envelope by changing the local geometry (mechanization wing), they generally camber changes depending on the phase of flight (landing, take-off). As controls, the aircraft they developed aeromechanical has effects with implications for the resistance structure of the wings, and the most important effect is the twisting of the wing. The article desires an analysis of the 2D aerodynamic profile with changes in curvature at trailing edge. This study extends an existing semiempirical approach to high-lift analysis by examining its effectiveness for use with a three-dimensional aerodynamic analysis method.
