　　A three-dimensional structured RANS solver based on the arbitrary Lagrangian-Eulerian (ALE) formulation with a dynamically deforming mesh algorithm is used and validated with the wind tunnel and ballistic range data available in the literature.Roll and pitch damping derivatives are calculated from load history of the unsteady flow around the model.A standard research configuration, known as the Basic Firmer, is studied under forced pitching and rolling conditions.Pitching and rolling motions with oscillation are analyzed at supersonic Mach numbers ranging from 1.5 to 2.5.Predicted results showed good agreement with the available wind tunnel data.
