民用客机增升装置气动噪声研究进展

The Progress of Civil Aircraft High-Lift Noise Research

随着民用飞机数量的快速增加,航空噪声问题日益引起世界范围的关注。增升装置作为重要的机体噪声源之一以其流动复杂性和声源多样性成为民用航空气动声学的难点之一,欧美各国为此开展了大量的研究。总结了增升装置气动噪声的产生机理以及控制措施的研究现状,在此基础上还特别关注了目前工业部门气动与声学的设计思想及需求。

With the rapid development of the civil transportation, there are more and more attentions paid on avia- tion noise in the whole of the world. As one of the important airframe noise sources, the high lift noise became a puzzle because of the complexity of the flow and the multiformity of the source. The European and American made a mass of research. The development of mechanism and the reduction measure of the high lift noise is summarized and the thought and requirement of the industry about the aerodynamic and aeroacoustics design of the high lift is referred in particular.
