| 摘 要： | 本文对运动物体空气动力噪声的降噪问题进行了理论上的和实验上的探讨。根据翼型发声机理的分析和发声量的估算 ,给出了钝物体的一种发声估算方法。作为实例 ,对飞机Φ70mm的受油圆杆的发声进行了估算 ,其结果同试飞及风洞试验十分一致。

| Abstract: | The problem reducing aerodynamic noise from moved body has been discussed theoretically and experimentally in this paper.A way of noise prediction for a blunt body is based on the analysis of noise generator mechanisms and prediction of noise emission for the airfoil.For example,the prediction of noise emission for aircraft receiver support is agreement with the datum from the flight test and the wind tunnel model test. |
