| 摘 要： | 为研究钝前缘对乘波构型气动特征的影响,设计了具有不同尺度钝前缘的乘波体,采用数值计算对钝前缘乘波体气动特征进行了计算,结果表明钝前缘使得乘波构型流场结构改变,气动特性严重下降.为了兼顾防热要求和气动特征,设计了具有部分钝前缘的乘波构型,数值计算结果表明该外形在保证加热严重区域防热要求的同时能够具有较好的气动特征.

| Abstract: | To investigate the changes in aerodynamic performance of waveriders with blunt edges,waverider configurations with different blunt edges were developed.Numerical simulation shows that blunt edges greatly change structures of flow fields and the lift to drag ratio decreases when blunt edges scale increases.A waverider configuration with partial blunt edges was developed and proved to be better at lift to drag ratio. |
