风扇部件是民用涡扇发动机关键部件之一,自20世纪60年代以来在气动设计等方面发生了显著变化,其发展支撑了民机的更新换代。对民机风扇叶片的发展历史进行了回顾,对典型设计特征和参数进行了总结。着重介绍了民机风扇叶片的叶片数、叶尖切线速度、气动叶型设计、降噪设计、材料工艺等发展变化,对其内在原因进行了分析,并评述了其发展趋势。
Fan components are one of the key components of civil turbofan engines. Since the 1960s, significant changes have taken place in the aerodynamic design, and their development has supported the upgrading of civil aircraft. The history of the development of civil fan blades is reviewed, and the typical design features and parameters are summarized. This paper mainly introduces the development and change of blade number, tip tangential speed, aerodynamic blade design, noise reduction design and material technology of the fan blades of civil aircraft. The internal reasons are analyzed and its development trend is also discussed.
