Methodology development for coupled aeroelastic analysis of wing flutter
An integrated computational fluid dynamics and computational structural dynamics (CFD-CSD) approach is being developed for the simulation and prediction of transonic flutter. The CFD solver was based on an unsteady, parallel, multi-block, multi-grid, structured, finite volume algorithm for the Euler/Navier-Stokes equations. The solution of the flowfield is coupled with the structural dynamics by a fully implicit method. The twodimensional (2D) CSD solver is based on the time integration of a two-degree-of-freedom (two-DOF) structural model while the three-dimensional (3D) CSD solver is a finite element model. The coupled CFD-CSD method simulates the elastic system directly in the time domain to determine the stability and response of the aeroelastic system.
