| 摘 要： | 噪声设计已成为现代直升机设计的重点。本文从理论上推导了Farassat1A公式,建立了可进行预估直升机旋翼厚度噪声的方法,并对1/4的UH-1直升机旋翼模型和某型机进行了理论计算,研究了桨叶桨尖马赫数、桨叶翼型相对厚度等因素对厚度噪声的影响。

| Abstract: | The noise design technology has became importance in modern helicopter design. In this paper,the Farassat 1A formula has been induced,and has been used to compute the UH-1 1/4 scale main rotor model and one sample helicopter main rotor.This paper also made some research on the factors which can affect the thickness noise variety. |
