Abstract: A time-marching aeroelastic analysis is enhanced by combining aerodynamic modeling techniques with CFD. This enhancement significantly reduces the computation time required to accurately predict critical flight conditions. Furthermore, this method is tested over a wide range of mach numbers and proven valid in all reasonable cases. It is shown that estimated flutter boundaries obtained by this method are sufficiently close to the flutter boundaries predicted by the Euler method, that the enhanced CFD solution may then be used for refinement which requires significantly fewer transient calculations.
