Paper Abstract

A simple numerical method has been developed to predict the trajectories and impact characteristics of solid particulate material after traversal of the complex flow structure existing over a hypersonic forebody. Specifically, particle impact characteristics are examined for an aerodynamic structure incorporating a forebody window assembly which is shielded from aerodynamic heating via gas coolant flow. For calculation of the flow field properties inside the shock layer surrounding the forebody, a computational fluid dynamics (CFD) numerical solution of the hypersonic compressible flow field is employed. The nature of the aerodynamic drag acting on the particle is thoroughly investigated.
