乘波体预压缩性能试验研究*

Experimental Investigation of the Pre-Compression of a Waverider

摘要: 按马赫数12设计的钝化前缘乘波体缩比模型在M5．3风洞中完成了四个迎角下的吹风试验，研究进气道入口截面的流场品质和不同迎角下的预压缩效果。试验表明在马赫数5．3来流下钝前缘乘波体型面预压缩性能和总压恢复性能明显地优于等牛顿冲角法设计的型面。

Abstract: A waverider model designed at Mach 12 with a rounded leading edge is experimentally investigated in the Mach 5．3 100mm×100mm hypersonic wind tunnel．The results of waverider aerodynamic characteristics such as the pre-compression and the total pressure rec
