Abstract: Near space hypersonic flight vehicle is the key weapon development direction for many military powers in today's world, because of the high speed, high breaking ability and high killing ability, etc. Aerodynamic force and heat are two extremely important indicators for hypersonic flight vehicle, becoming the main research for hypersonic flight technology. In this paper, research status on aerodynamic force and heat of near space hypersonic flight vehicle was reviewed from engineering calculation, numerical simulation and experimental study.
