摘要
直升机旋翼噪声是直升机工业发展面临的重大问题之一,因其问题复杂,涉及的学科多,一直吸引众多研究者的注意。本文对直升机旋翼噪声的研究进行概述,介绍了旋翼空气动力学的发展,旋翼噪声的理论与试验研究,降低旋翼噪声的方法和智能旋翼研究。最后对未来旋翼噪声研究做出了展望。
Helicopter rotor noise is one of the most important problems among helicopter manufacture.The problem is so complex and involves many domains that lots of researchers are interested in. This paper gives a brief overview of research on helicopter rotor noise include describing the progress of helicopter rotor aerodynamics,introduing theoretical and experimental research on rotor noise,approaches of rotor noise reduction and research on smart rotor.Finally,prediction of the research on rotor noise is presented.
