This paper discussed the implementation of a nonlinear static aeroelastic analysis framework based on CFD/CSD coupling method. For fluid-structure interaction (FSI) problems, a conventional serial staggered (CSS) procedure is applied to generate a loosely-coupled scheme. The Reynolds-averaged Navier-Stokes equations are solved for the fluid, and a geometrical nonlinear finite element method is used for the structure. The morphing of the mesh is achieved using a spring-TFI (trans-finite interpolation) hybrid approach with rotation correction. The proposed nonlinear static aeroelastic framework is demonstrated on a very flexible high-aspect ratio wing, which is currently undergoing wind tunnel testing.
