摘　　要：对军用装备的投放过程建立偏微分方程组模型,确定满足投放要求的最佳投放位置和投放速度,分析了在投放位置和投放速度均存在合理误差的情况下,落地点的区域范围,并进一步对投放轨迹进行修正,以减少由于投放位置和投放速度的误差对投放精度的影响,通过采用蒙特卡罗方法进行仿真模拟,结果表明,该偏微分方程组模型以及通过对装备投放轨迹修正更加有利于实现对投放过程的精确控制。A partial differential equations model is built for the drop process of military equipment,with which to determine the best placement and speed to meet the drop requirements,and discusses the regional scope of landing point in the case of reasonable error in the delivery point and speed,and corrects the drop trajectory in order to reduce the influence of drop precision by the error of delivery point and speed. Using the Monte Carlo method,we simulate the drop process. The results indicate that this partial differential equations model and the correction of the drop trajectory will help improve the accuracy of the delivery process and the drop effect significantly.
