Hypervelocity flight

Progress in aeronautics and astronautics within the past decades has been remarkable because people have learned to master the difficult feat of hypervelocity flight. A variety of manned and unmanned aircraft have been developed for faster transportation from one point on earth to another. Similarly, aerospace vehicles have been constructed for further exploration of the vast depths of space and the neighboring planets in the solar system. 

Ablative systems are not limited by the heating rate or environmental temperature, but rather by the total heat load. In spite of this limitation, however, the versatility of ablation has permitted it to be used on almost every recent hypervelocity atmospheric vehicle. Moreover, it appears that ablation will continue to be favored as the primary thermal protection method for future flight vehicles.
