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。 Based on the analysis of the force characteristics of the airplane and the effect of the ground effect and the pull force of the umbrella on the airdrop during the airdrop state, the model of the aircraft center of mass, the centroid kinematics and the attitude dynamics are established by using the isolation method. Machine response characteristics. Based on the results of numerical simulation, the research emphases are put forward, and the complicated airdropping process is reasonably simplified, which lays the foundation for the design of airdrop control law.
