The gust model is based on adding artificial gust velocities into the governing equations, this method is usually referred to as Disturbance Velocity Approach. A series of gusts is used to measure response of the aircraft and to establish dynamic gust model. The movable control surfaces are defined and their efficiency is assessed by the CFD using the mesh deformation technique in the unsteady simulation. Finally, the dynamic model based on both the gust data on one hand and on the control surfaces action on the other hand is used to prescribe movement of the control surfaces with the aim to alleviate the gust interaction. The required time response of the control surfaces is studied to clarify limits of this alleviation technique.
