摘要
开展变楔角参数化乘波器的研究。研究中考虑了粘性效应,分析了不同设计参数对乘波器气动性能的影响。对比MAXWARP乘波器设计结果和数值求解NS方程的结果,验证了变楔角参数化乘波器设计方法的正确性。分析了不同的设计参数对乘波器气动性能的影响,为研究复杂的乘波器设计和优化规律提供了一个途径。参数化乘波器设计可方便的控制乘波器的外形尺寸,使乘波器的应用性大大提高。
In this paper, the parametric waveriders designed with variable wedge angle is being studied. During the design process, viscous effect is being considered, and the effect of change design parametric to aerodynamic is being analysis too. Via validate with MAXWARP waveriders generate programmer and NS equation numerical simulation, it demonstrates that the parametric waveriders design method is fulfill. With the parametric analysis the design parametric effect to aerodynamic, it leads a way to understand more complex waveriders design and optimization. Because parametric waveriders design method can control the configure of result waveriders more easily, it makes parametric waveriders design more close to application.
