Abstract: The efficacy of the simulated transpiration boundary condition applied to the steady and time-marched Euler solutions to aeroelastic problems has been addressed in this study. Emphasis is placed on use of the method for significant savings in the computation time for aeroelastic simulations and predictions. A variety of geometries have been tested over a Mach number range from low subsonic, to supersonic. Results are presented which are representative of the entire test matrix, and include lifting, and non-lifting examples. Results over the entire range of Mach number indicate that the method yields accurate results even for significant surface deformations, and is very well suited for the task of local stability analysis for predicting aeroelastic divergence and flutter for configurations of practical interest.
