Computational Fluid Dynamics based simulation of trimmed igh t is now becoming possible but requires the incorporation of a controller which commands control surface deections. This paper describes eorts to realise this for a generic gh ter conguration in longitudinal motions. The incorporation of the igh t mechanics equations and controller into the CFD solver loop and the treatment of the mesh, which must move with both the control surface deformations and the rigid motion of the aircraft, are described. This work is a contribution to a wider eort towards the simulation of aeroelastic and igh t stability in regions where nonlinear aerodynamics, and hence potentially CFD, can play a key role. Results demonstrating the coupled solution are presented.
