Abstract
The boundary element method provides a low-order computational model for investigating unsteady wing response. This method is applied here to investigate the effect of fixed wing geometry on the blade-vortex interaction (BVI) problem. The method has been validated using a harmonic Sears gust as well as three-dimensional BVI analytical results for thin, flat, rectangular wings. It is shown that wing taper and twist do not significantly affect the BVI response while sweep greatly reduces it.
