Static aeroelastic computations are made using a C++ executable developed for closely coupled fluid-structure analyses. The fluid flow is modeled using Euler/Navier-Stokes equations and the structure is modeled using finite elements. The FORTRAN-based fluid and structure codes are integrated in a C++ environment in which the flow and structural solvers are treated as separate object files, and the data exchange between them is accomplished using I/O. Use of this technique to solve transonic flow over a partially flexible surface is presented, and its ability to accurately predict flow-induced deformations associated with nonlinear structures is demonstrated.
