These configurations demonstrate the interaction between a rigid structure and fluid, as well as the interaction between a flexible structure and fluid. A closely-coupled approach is used to perform the combined fluid and structure interaction computations. The flow solver is an unsteady, implicit, three-dimensional, multi-block, pressure-based Navier-Stokes solver. The structure solver for the AGARD wing model is based on a linear, time-invariant model derived via classical structural finite elements whereas the flexible structural solver is based on a non-linear dynamic membrane model with the material obeying the hyperelastic Mooney's model. Suitable interfacing techniques are incorporated to couple and synchronize the flow and structure solvers. We present unsteady computations performed on both rigid and membrane wings to highlight the computational characteristics. KW - DO - 10.3970/cmes.2002.003.773
