A REVIEW ON HYPERSONIC VEHICLES AND KEY TECHNOLOGIES

This paper begins with a classical definition of hypersonic,some physical phenomena pertinent to hypersonic flight,the covered range of the hypersonic flight and the features of design process.The differences between AHV(hypersonic airbreathing vehicles)and RHV(hypersonic rocket vehicles)are discussed,with a table showing temperatures.In the second part,the paper puts hypersonic vehicles in a military background. A historical perspective of hypersonic vehicles is given in form of a table with milestones,accompanied with some lessons learned from the past and relevant for the future.In the last part,a typical design process,development strategy,technology program,and key technologies of hypersonic airbreathing vehicles are reviewed.
