摘　　要：运输机常常使用降落伞空投装备和物资。为了研究影响降落伞落点散布的因素,建立了降落伞运动模型和随机风模型,并使用蒙特卡洛法进行了仿真实验,评估了三个空投初始条件和随机风对降落伞落点散布的影响。仿真实验结果显示,随机风对降落伞落点散布的影响显著大于三个空投初始条件。文章的研究结果可以为预测空投降落区域和空投物回收提供理论支撑。It’s conventional for transport aircraft to drop equipment and cargos using parachutes.To study the impact factors of the dispersion of parachute’s landing positions,a parachute model and a wind field model were built.Based on these models,Monte Carlo method was applied for a simulation research on the impact factors of three airdrop initial conditions and random wind.The simulation results showed the random wind was the greatest impact factor.This study can be used to predict the landing area of airdrop and help the search of airdrop cargos.
