Research on Integration Method of Hypersonic Vehicle

针对高超声速飞行器一体化设计方法现状的分析,阐明了吸气式发动机与乘波体飞行器之间高效的一体化对于高超声速飞行的重要作用,并从理论、原理、设计方法3方面进行介绍。在激波理论方面,通过从直线激波的求解拓展到二次曲面激波的求解,为3维曲面激波的研究提供了帮助;在乘波原理方面,将乘波原理从外流乘波拓展到内流乘波,继而提出1种兼顾内外流需求的双乘波原理,深化了乘波原理的内涵;在设计方法方面,对于基本流场的气动设计问题,提出更加高效的一体化气动反设计方法。综上分析并归纳出准3维内外流一体化乘波理论与方法,从而在现有“准3维”研究体系上,构建并完善了全3维内外流一体化乘波理论与方法,对于复杂3维超声速内外流一体化设计技术的发展具有一定借鉴作用。

In view of the analysis of the present situation of the integrated design method of hypersonic vehicle,it was expounded that the efficient integration between airbreathing engine and waverider body vehicle played an important role in hypersonic flight,and introduced from theory,principle and design method.In the aspect of shock wave theory,it was helpful to study the three dimensional curved shock wave by extending it from the solution of linear shock wave to the solution of quadric curved shock wave.In the aspect of waverider principle,the waverider principle was extended from the external flow waverider to the internal flow waverider,and then the dualwaverider principle with the requirement of both internal and external flows was put forward,and the connotation of the waverider principle was deepened.In the aspect of design method,a more efficient integrated aerodynamic inverse design method was proposed for the aerodynamic design of the basic flow field.The waverider theory and method of quasi-three-dimensional internal and external flow integrated are analyzed and summarized.Thus,based on the existing"quasi-three-dimensional"research system,the theory and method of integrated waverider of full three-dimensional internal and external flow are constructed and perfected,which is helpful to the development of complex three-dimensional supersonic internal and external flow integrated design technology.
