航空动力装置试飞旋转件载荷测量技术

摘要

航空动力装置旋转件的飞行载荷是其工作可靠性和寿命分析评估的重要技术指标,这一重要指标必须通过飞行实测.重点论述了载荷测量技术方法和技术难点及所要关注的技术问题,并用实例阐述了某型复合材料螺旋桨飞行应力测量技术的应用.%The flight load of aviation powerplant is a significant engineering index in working reliability and life analysis and assessment, so it must be obtained by actual measurement in flight test. The method and nodus of load measuring technique are detailed. Besides the focused technique issue is propounded, and the stress measurement of some composite propeller in flight test is also illustrated.
