The paper describes and analyses potential concepts for gust alleviation at transonic speeds applied on a forward swept transport aircraft configuration. The main objective is to reduce structural weight by minimizing gust induced loads. Both inviscid and viscous aerodynamic simulations are performed for analysis. A gust study reveals a critical gust wave length of 50m leading to highest aerodynamic loads at cruise conditions. Gust induced separation is observed for particular cases. Deflection of a wing tip flap and the aileron at the outer wing have a remarkable short response time and offer strong flow actuation to reduce gust loads.
