摘要
在分析空投状态下飞机的受力特征及地效和牵引伞拉力对空投过程影响的基础上,应用隔离法建立了飞机质心动力学、质心运动学、姿态动力学模型,计算评估了空投过程载机的响应特性。基于数字仿真结果提出了超低空重装空投的研究重点,并对复杂的空投过程进行了合理的简化,为空投控制律设计奠定基础。
According to the aerodynamic analysis when airdrop is on,the establishment of dynamic centroid model,kinematic centroid model and attitude dynamic model were accomplished,using separating method,with the screen and parachute effect being considered.The respond of the plane during the airdrop process was evaluated.Grounded on the results of mathematical simulation,the keystone was abstracted for heavy cargo airdrop on low altitude and rational simplification was made.All these have contributed to airdrop control law.
