Research On The Development Of Hypersonic Vehicle Technology

Hypersonic vehicle is an important future research direction of aerospace. Hypersonic vehicle technology researches will promote the overall level of science and technology. Hypersonic weapons have a superior performance, it is even more necessary for the national security interests. The great power had raced to put the development of hypersonic technology as a national strategic objective.This paper studies the essentials which impact the development of hypersonic vehicle technology, the current modes, the basis and the principal policy in developing hypersonic technology are advanced.Characteristics of hypersonic fluid are analyzed, the methods of calculating aero thermal load are summarized, the elements which are able to affect aero thermal load are canvassed. Induced three modes of the hypersonic weapon thermal manager and generalized the development of ablator.According to the way of jet propulsion, rocket or air breath, assort the hypersonic vehicle into HRV and HAV. The viable technology target of HAV is educed. Merits and the development potential of wave-rider are analyzed. Based on the research hereinbefore, induced the factor in hypersonic vehicle designing, summarized elements and the development of RBCC and TBCC. The way of launching, boosting and reentering of hypersonic vehicle are analyzed.Separated the course of developed country's hypersonic vehicle technology into three phases, advanced the current modes is'three methods to be an integer', the basis is'developing ladder likely'and the principal policy is'seize the pivotal technology and develop propulsion first'in developing hypersonic technology.The research of this thesis is helpful to enhance the cognition of hypersonic vehicle technology and has certain reference value for the developing and programming of our country's hypersonic vehicle technology research.
