Abstract

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. Under Phase I of this SBIR, the feasibility of two enabling computational technologies was studied 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. Pathways for integrating these computational technologies in comprehensive, CFD-based, transient, nonlinear aeroelastic codes were also identified. Under Phase II of this SBIR, it is proposed to mature these computational technologies and ready them for commercial applications.
