摘　　要：为了明确牵引伞投放后到货物开锁运动这一过程的变化状态,通过对牵引伞运动状态进行分析,建立牵引伞运动轨迹模型,引入实例对牵引伞随时间变化的运动状态进行计算,并根据计算数据拟合出牵引伞随时间的运动轨迹曲线,实现了牵引伞运动轨迹的可视化。该计算模型为牵引空投中牵引伞投放位置控制以及飞机姿态调整提供了参考。In order to clarify the state change during the traction umbrella releasing the cargo to unlocking,based on the analysis of the motion state of traction umbrella, established motion model of traction umbrella and introduced examples to calculate the motion state of traction umbrella changing with time, then iftting the trajectory curve of traction umbrella over time according to calculated data, realized the visualization of traction umbrella trajectory. This model provides reference for the airdrop position control and aircraft attitude adjustment.
