| 摘 要： | 在跨声速风洞中研究了声激励对于可压缩流中细长旋成体大迎角流动非对称性的影响效果。结果表明，在可压缩流场中，声激励对于细长体典型迎角下的流动非对称性依然有着一定的影响，但由于高速风洞中流场本身的湍流度较高，声激励效果要比低湍流度不可压缩流中的影响弱。

| Abstract: | The effect of acoustic excitation on the flow asymmetry over a slender body in compressible flows was investigated in a transonic wind tunnel. The results show that acoustic excitation has some effect on the flow asymmetry at typical angles of attack in compressible flow field. But the effect is more unconspicuous in compressible flows than in uncompressible flows because of the higher turbulence. |

| Keywords: | high angles of attack slender revolution body acoustic excitation flow asymmetry |
