摘要
基于飞行器外形参数化设计,通过分析乘波构型外形设计参数,结合飞行器前体/进气道一后体/喷管一体化设计思想,进行了乘波机的概念设计研究。在性能计算中,对生成的乘波飞行器进行了设计点和非设计点包括升力、粘性阻力、波阻和升阻比、容积效率等各主要性能指标在内的性能计算。通过性能验算初步论证了本文进行的乘波飞行器外形参数化设计方案是可行的,所提出的参数化体系可以进一步为优化设计工作所利用。
Based on the parametric design of aircraft shape, analyzing waverider design parameters, and combining with the aircraft forbody/inlet-aftbody/nozzle integral design, a conceptual study on the waverider aircraft was mainly presented. Both on-design and off-design aerodynamic performances calculations were carried out to demonstrate the feasibility of the design cases. It shows that the parametric design can be served for the further optimum design work.
