An Approach to the Gust Problem with Interfering Profiles

Part of the Notes on Numerical Fluid Mechanics and Multidisciplinary Design book series (NNFM, volume 112)


The mutual influence of two profiles is studied in subsonic and transonic 2D viscous flow. The profiles are arranged such that the second one is located downstream of the first one similar to the configuration of a tail plane behind a wing. The physical effect is that of a gust generator. The unsteady wake of the leading profile encounters the trailing profile and effects a load change. A first simplified attempt has been made using a rigid grid where both profiles execute a synchronous heaving motion.
