An important aspect of aeroservoelasticity is the analysis of interactions between rigid, elastic, and control modes. The stability and control derivatives were determined for a high number (90) of flight test conditions expressed in terms of Mach nu

[Abstract] In this paper, a new formulation for a ground dynamics model of a commercial two-engine helicopter is validated after touchdown. The inputs of the ground dynamics model are the velocities and angles at touchdown, and its outputs are the fo

Two numerical algorithms are presented here: the integration of the Poisson equation of attitude and the calculation of the angles from the elements of the matrix of attitude. The method here suggested lies in the use of a fast algorithm of Wilcox ty

In this paper, a new technique for a helicopter model estimation based o n flight test data is presented. The state space helicopter models, for each flight condition, are presented. The method is automatic and is applied when one knows the motion pa

The unsteady aerodynamic forces acting on an F/A-18 aircraft are calculated in the frequency domain using a doublet-lattice method (subsonic regime) or a constant-pressure method (supersonic regime). To study the effects of the control laws on a flex
