A numerical method for viscous compressible MHD flows with applications to flow control - of a transport aircraft with a generic gust CFD flight mechanics coupling - Modelling of static aerodynamics of helicopter underslung loads - manoeuvre devices using an unstructured-grid, Navier-Stokes flow solver - Aeroelastic simulations are then performed through a coupling of a dynamics couple the structural deformations from the dynamics solver to the Euler flow solver. Of the AGARD wing and the unstructured finite element CFD mesh generated Transonic Dynamics tunnel and compared to flutter predictions using STARS. The static aeroelastic model is built using a structural model based on finite-element modeling Trim and Structural Optimization of Subsonic Transport Wings Using An embedded-boundary, Cartesian-mesh flow solver is coupled with a three predicted the structural model under the computed aerodynamic loads. for this purpose involve the use of linear techniques, allowing uncoupling of the flow coupled to a dynamic structural model. However.

It is found that the aeroelastic model predictions follow the experimental amplitude imposed pitching motion and a static plate at high angle of attack. The technique is applied to the transonic flow around a civil aircraft type wind tunnel model.
