飞机舰面动载荷计算方法研究及试验验证

CALCULATION OF AIRCRAFT DYNAMIC LOADS ON SHIP-DECK AND TEST VERIFICATION

舰载飞机的舰面动载荷是结构的临界设计载荷。针对常规方法下载荷计算的设计已不能满足舰载飞机非常规工况(例如弹射拦阻、自由飞钩住、偏心着舰等)载荷计算的设计要求的问题,研究和建立了一套完整的全机动载荷计算的设计方法和流程,并以某型飞机全机落震试验为例,通过与试验数据的对比分析,验证了该设计方法和流程的合理性和可行性。

The carrier-based aircraft dynamic loads on the ship-deck are a critical design parameter of the structure.Often the conventional load calculation method can not deal with the carrier-based aircraft abnormal loads(such as in cases of catapult and arresting,free flight hook,off-center landing of carrier-based aircraft),a complete set of design methods and calculations of full-aircraft dynamic loads is proposed,and the dynamic load calculations are made for the full-aircraft dropping test of a certain type of aircraft,and the comparison with the test data verifies the rationality and the feasibility of the design methods and calculations.
