摘　　要：针对大型运输机空投精度影响因素问题,提出一种基于蒙特卡罗方法的空投仿真统计试验方法,建立了空投落点概率偏差计算模型,考虑空投条件变化的影响,对空投落点概率偏差进行了仿真计算。给出了应用该方法的具体步骤,通过示例的仿真计算,分析了3种空投条件对空投落点概率偏差的影响规律。仿真结果显示,在估计空投落点散布时,必须认真考虑速度偏差的影响,俯仰角偏差和高度偏差的影响相对较小。aircraft by calculating taking For the problem of airdrop position precision calculation when cargo drop from a large transport parachute, a method was proposed based on Monte Carlo method. A model was built up for airdrop position error probability. The the influence of airdrop condition changing airdrop position error probability was calculated out by into consideration. The influence rules of three conditions were analyzed according to the result of simulation. The simulation result also shows that： 1 ） the influence of velocity deviation must be taken into consideration when estimating the airdrop position; and 2 ） the influence of pitch deviation and altitude deviation is relatively less. The study supplies a theoretical basis for safe aviation and precise airdrop.
