| 摘 要： | 以高超声速技术为研究背景,开展高超声速乘波飞行器设计方法研究.在已有乘波构型生成方法基础上,采用相交楔锥生成多级压缩的乘波构形.并通过对乘波器的前缘进行钝化,进行了气动热特性数值研究.使乘波体在气动力层面上具有尖前缘,保持高升阻比特性,而在气动热层面上具有钝前缘,降低气动加热强度.结果表明,这为高超声速飞行器的气动防热设计开辟了新途径.

| Abstract: | To study hypersonic technology,several methods are investigated to design Waverider aerodynamic configuration.Base on the study of waverider,a new conceptual hypersonic waverider is designed by showing a sharp leading edge in aerodynamic perspective and an artificially blunt leading edge,in aerothermal perspective.The results show that it can be used for the design of aerothermodynamics. |
