本文提供了翼型内部声激励增升效果的实验研究结果，并着重探讨了声激励增升的机理。实验结果表明在分离点前或分离点后位置作激励都有很好的增升效果，且机理在本质上是一样的。本文所描述的关于声激励增升机理的初步结论，为进一步进行这一方面的工作提供了有益的启发 In this paper, experimental results on the enhancement of acoustic excitation inside airfoils are provided, and the mechanism of acoustic excitation enhancement is emphatically discussed. The experimental results show that the excitation before or after the separation point has a good promotion effect, and the mechanism is essentially the same. The preliminary conclusions about the mechanism of the increase of acoustic stimulus described in this article provide useful inspiration for further work in this field
