摘要
本文首先介绍了乘波外形的基本概念和空天飞机采用乘波外形的优点,然后介绍了利用楔的流场和圆锥流场构筑乘波外形的方法和气动力性能的计算公式,在简单地评述了乘波外形优化工作的进展之后,重点介绍了考虑粘性的乘波外形优化方法和乘波外形气动力性能计算与实验结果的比较。对乘波外形与超燃冲压发动机一体化方面的近代工作也作了介绍。最后,对乘波外形今后的研究工作提出了建议。
The basic concept of waverider and the advantages thatwaveriders apply to aerospace plane are introduced.The design methodfor waverides generated from the flow field of the wedge and the circu-lar cone and calculating methods of its aerodynamic performance arepresented.The progress of research works for optimized waveriders isreviewed briefly.It puts emphasis on the optimum methods of waver-iders in addition to taking viscous effects into account and making acomprison between calculating results and wind tunnel testing results.The recent research works about the integration of scramjets withwaverider configurations are introduced.Finally,the suggestions offurther research works about waveriders are put forward.
