乘波体设计方法研究进展

Review on the Design Methodology of Waverider

气动外形设计是高超声速乘波飞行器总体设计的主要内容,也是关键技术之一。本文概述了乘波体设计方法的发展现状,重点总结了正设计方法、反设计方法和生成体法三类方法的研究进展,并分析了三类设计方法的优缺点。乘波体的实用性还有待于进一步提高,应合理借鉴常规飞行器的成熟设计方法,并且将现有设计方法与智能变形等新技术进行有机结合,以解决乘波体在实用性上存在的问题。

The aerodynamic configuration design of hypersonic vehicle is the main content in preliminary design stage.It is also one of the key technologies.The development status of waverider design methods were summarized,the research progresses on positive design method,reverse design method and shock generating body method were reviewed respectively,and the merits and faults of these three design methods were analyzed.It is proposed to draw lessons from mature design methods of conventional aircraft reasonably,and combining these classics design methods with novel methodology and technology,which can improve the practicability of waverider,and can also enhance the design flexibility of hypersonic waverider vehicles.
