摘要
为了对军用运输机空投时的飞机响应进行分析与评估,给飞行载荷和操稳设计提供基本依据,将飞机与货物视为一个整体系统,建立空投过程中载机与货物的动力学方程;根据《军用飞机结构强度规范》中的空投和空投阵风准则进行了仿真计算,给出了空投过程中飞机的动响应与部件载荷时间历程。仿真结果表明,所提供的方法能够满足运输机空投时的飞行载荷分析要求。
Aircraft＇s dynamic responses of cargo airdrop should be analyzed and evaluated in detail so as to supply the design basis for the flight loads and handling quality design. Taking the aircraft and cargos as an integrated system, the dynamic equation for the aircraft and cargos during airdropping was estab- lished for analysis and evaluation of aircraft response in the case of airdrop by military transport aircraft and providing the design basis for flight loads and handling quality. The simulation was conducted according to the airdrop and airdrop gust guidelines which are described in the Military Aircraft Structure and Strength Specification. The aircraft＇ s dynamic responses and component＇ s dynamic loads during air- drop were demonstrated. Simulation results indicate that the method meets the requirements for flight loads analysis of transport aircraft airdrop.
