CFD (Computational Fluid Dynamics)-based nonlinear computational aeroelasticity methods have been successfully demonstrated for the flutter analysis of complete aircraft configurations in subsonic, transonic, and supersonic airstreams, at low to moderate angles of attack, for clean wing configurations, and when viscous effects can be neglected. It is proposed to research and investigate the feasibility of two enabling computational technologies for expanding the scope of these methods to high-angle of attack, viscous aeroelastic applications such as buffeting. These two technologies are computationally efficient algorithms for updating dynamic CFD grids that are robust in the boundary layer and also viable for modeling the deployment of control surfaces, and time-accurate implementations of suitable turbulence models on moving grids. It is also proposed to identify pathways for integrating these computational technologies in comprehensive, CFD-based, transient, nonlinear aeroelastic codes.
