新型乘波体设计及其研究现状

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。新型乘波体增强了实用性,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,以期为乘波飞行器的研制打下坚实的基础。

Design and Research Status of Novel Waveriderand

Combining mature design methods of conventional aircraft and smart morphing technology with classics designmethods of waverider can produce some novel waverider, such as multistage compression waverider, multistage waveriderand morphing waverider. The development status of these novel waverider was summarized, and the research progresses ofthese novel design methods of waverider were reviewed. It was show that the aerodynamic performance of these novel wa.verider substantially outperformed the classicswaverider in off-design regimes. So the practicability of these novel waverid.er was also increased, they could be used in the aerodynamic configuration design for wide-speed range hypersonic vehi.cle. Several application cases demonstrated the potentiality of these novel waverider in the aerodynamic configuration de.sign 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.
