摘　　要：针对某型飞机挂装新型武器后着陆重量超过设计着陆重量、着陆后需要对相关结构进行分解检查的情况,通过仿真计算和飞行试验数据分析,在保证结构安全同时又兼顾外场可实施性的情况下,提出了飞机超重情况下着陆时的边界过载,以此建立了超载着陆后结构是否需要分解检查的评判依据和逻辑关系。该方案已在某型飞机的试飞工作中实施。For the modification to an aircraft, when the new-developed missiles mounted, the aircraft will be overweight during landing, which will cause complex disassembly and check for landing gears to detect any possible damages according to requirements of the maintenances manual. In this paper, a overweight landing monitoring method was established based on the diagnosis of landing gear ground loads, which can help ground crew decide whether or not the landing gear needs to be dismounted and checked. The method was developed by establishing the relationship between landing gear loads and airframe accelerations, which are based on large amount of flight test data and dynamic simulations. The method was applied to the flight test of the aircraft and showed good effects.
