Abstract

This paper investigates active gust alleviation on a forward swept transport aircraft at transonic speeds. A gust study reveals a critical gust wave length of 50m leading to highest aerodynamic loads under cruise conditions. Gust induced separation is observed for particular cases. Deflection of a wing tip flap and aileron at the outer part of the wing have a remarkable short response time and offer a very promising flow actuation to reduce gust induced lift. The droop nose can be used to control the pitching moment. The flap deflection angle has to be chosen carefully to avoid flow separation. Adding the aileron, increases the effectiveness of the gust alleviation system significantly.
