An overview of the materials/structures test methodology used in the development of hypersonic vehicle components is presented. Focus is on aerothermal methodology and weather/erosion testing. For the latter, testing techniques which evaluate particle impact effects on vehicles operating at supersonic through hypersonic speeds in particle laden environments are described. Such facilities for increasing velocities are: wind tunnels/sleds; arc facilities; aeroballistic ranges. It is noted that it is of particular importance to demonstrate that flight components such as leading edges, cowl lips, and structural panels will survive the aerothermal flight environment. Specific components can experience very high heating rates and surface temperatures from 1100 to 1950 C.
