Development of American typical hypersonic flight vehicles and its enlightenment

The development course of American typical hypersonic flight vehicles and their propulsion systems is reviewed.The development trend,experiences and lessons from those typical programs are analyzed.The hypersonic technology is considered as the important development direction of aviation and spaceflight of America.The flight vehicles and propulsion technology have the close relationship with the idiographic application and nation strategic requirement.The development mode coinstantaneous with multi-scheme were adopted to reduce technical risk.The research of hypersonic technology must follow the need of nation strategic development,and focus on the top planning and the technical inheriting.The development of propulsion technology should put great emphasis on the fundamental research,experimental equipment,key technology study and the application of preponderant technique.
