A simulation environment has been developed enabling the computation of the elastic and trimmed aircraft. It consists of a trim algorithm which is coupled with a procedure to account for the interaction between fluid and structure. The trim algorithm is based on a Newton method with a discretized Jacobian. It incorporates the six degreesof- freedom (DoF) flight-mechanics equations and thereby enables to compute different trimmed states. The fluid-structure interaction (FSI) procedure uses a partitioned approach to compute the flow around the configuration in static aeroelastic equilibrium. This simulation environment has been successfully applied to trim a rigid transportaircraft configuration in viscous flow as well as in inviscid flow with rigid and flexible wing.
