中文摘要:
      将乘波体设计方法与常规飞行器成熟的设计方法和智能变形等新技术进行结合,可以设计出新型的乘波体,如多级压缩乘波体、双(多)级乘波体和可变形乘波体。对近几年出现的几类新型乘波体的设计及其研究进展进行了总结。新型乘波体的总体性能得到了显著提高,多级压缩乘波体可充分发挥其预压缩性能,两(多)级乘波体在设计点和非设计状态下均具有良好的气动性能,可变形乘波体在宽马赫数条件下始终能保持优良的气动性能。新型乘波体的实用性增强了,可用于宽速域高超声速飞行器的气动外形设计中。应进一步拓展这些新型乘波体设计方法的应用范围,并深入开展宽速域高超声速乘波飞行器气动外形设计和性能分析,为乘波飞行器的研制打下坚实的基础。
英文摘要:
      Combining mature design methods of conventional aircraft and smart morphing technology with classics design methods of waverider can produce some novel waverider, such as multistage compression waverider, multistage waverider and morphing waverider. The development status of these novel waverider was summarized, and the research progresses of these novel design methods of waverider were reviewed. It is show that the aerodynamic performance of these novel waverider substantially outperforms the classics waverider in off-design regimes. So the practicability of these novel waverider is also increased, they can be used in the aerodynamic configuration design for wide-speed range hypersonic vehicle. Several application cases demonstrate the potentiality of these novel waverider in the aerodynamic configuration design for wide-speed range hypersonic vehicle. The application range of these novel design methods should be expanded, combined with other classics design methods to produce other more novel waverider. The waverider configuration of wide-speed range hypersonic vehicle should be investigated extensively and in detail.
