摘　　要：由于螺旋桨产生的滑流可以缩短飞机起降距离,因此降低了飞机对于机场跑道的要求。目前,螺旋桨在民用飞机和军用飞机上仍有大量发展和应用。我国飞机螺旋桨自主设计起步较晚,过去我国大型螺旋桨一直采用全金属实心桨叶,“新螺旋桨”是我国首次自行研制高性能复合材料螺旋桨。研制过程中,在气动力设计、结构强度、电调控制等方面遇到了一系列巨大挑战。《军用飞机结构完整性大纲》(GJB 775A—2012)作为飞机结构设计的顶层要求,在螺旋桨结构设计中依然发挥着重要作用,是保证新螺旋桨结构可靠性、经济性和产品寿命的重要手段。设计人员在研制中学习和贯彻《大纲》的要求和实施方法,克服了大量的技术难点和工程问题,最终成功地研制和装机了新螺旋桨。本文从《大纲》的五个任务出发,介绍了新螺旋桨研制中关于各个阶段任务的贯彻和实施,以及在此期间开展的有关理论分析和试验验证,系统地总结了《大纲》在螺旋桨结构设计中的实践和体会。希望文章能为今后同类产品的研制提供借鉴和参考。Propeller aircraft can shorten the takeoff and landing distance due to the slipstream on the wing generated by the propeller,thus the required length of the airport runway can be reduced.At present,propeller aircraft is still widely developed and used in civil and military aircraft.The independent design of aircraft propellers in China started much late,and large propellers in China have always used all-metal solid blades in the past.As a new generation of propeller,the"new propeller"is the first self-developed high-performance composite propeller.During the development process,a series of significant challenges were encountered in terms of aerodynamic design,structural strength,electrical control,etc..The Military Aircraft Structural Integrity Program(MASIP,GJB 775A-2012),as a top-level requirement for aircraft structural design,still plays an important role in the propeller structural design,and is an important means to ensure the reliability,economy,and product lifetime of the new propeller structures.The designers overcame many challenges while gradually learning and implementing the requirements of MASIP,and ultimately successfully developed and installed the new propeller.Starting from the five tasks of MASIP,this study introduces the implementation of various stages of tasks in the development of the new propeller,as well as relevant theoretical analysis and experimental verification carried out during this process.The practice and experience of MASIP in the propeller structural design is systematically summarized.It is hoped to provide a guidance for the design of similar products in the future.
