增升装置气动噪声研究现状与发展趋势

摘要

在对绿色航空发展要求、噪声适航标准、机体噪声概念介绍的基础上，对增升装置气动噪声进行了详细论述，包括数值分析技术、试验研究、飞行试验、降噪设计等的研究现状；阐述了增升装置气动噪声研究的重要性，提出重视机理研究和数值分析方法验证工作的观点，指出增升装置气动与噪声一体化设计的发展趋势。%Based on the green aviation requirements, FAR noise standards, air frame noise sources, the state of the art of aero-acoustics techniques including CFD, wind tunnel test, flight test and noise reduction are discussed in details. The importance of aero-acoustics research on high-lift devices is described, the viewpoint of paying regard to mechanism research and verifying by digital analysis method is presented and the future trend of high- lift devices aero-acoustics, i.e. the aero acoustics and high-lift devices integrated design, is clearly pointed out.
