摘要
高超声速技术项目"Hyper-X"不仅实现了在大气中的高超声速飞行,验证了超声速燃烧与一体化设计的核心原理,而且促进了世界范围高超声速技术的持续发展.分析了Hyper-X在高超声速基础技术和应用技术领域的研究过程,特别是理论计算、地面试验和飞行试验相结合系统解决所面临的主要空气动力学问题的研究特色,尝试在气动研究方法学上归纳整理Hyper-X研究思路和方法,指出所具有的分解与集成、递进与过渡、知识与准则、验证与确认等方法学精髓.还介绍了该方法学在解决吸气式高超声速飞行器主要气动问题方面的一些应用.
Hypersonic technical project ＂Hyper-X＂ not only makes use of the hypersonic flight within the atmosphere and verifies the core principles of supersonic combustion and airframe integrated propulsion design, but also promotes the sustainable development of the worldwide hypersonic technology. This paper analyzes the research progress of Hyper-X in fundamental and applied hypersonic technologies, especially those combining theoretical computations and ground tests with flight tests to solve major aerodynamic problems systematically. The ideas and methods of Hyper-X aerodynamic researches are reviewed on the level of methodology, and the essence of the methodology includes such as the decomposition and integration, the progressive and transition, the knowledge and standards, the verification and validation. Some applications of the methodology in solving key aerodynamic problems arising from hypersonic airbreathing vehicle are also discussed.
