摘　　要：针对无伞空投精确性、可靠性的技术要求,提出一种精确计算最优投放点的方法。通过搭建标准条件下的投放点-落点数据库,结合神经网络拟合算法,训练得出所有条件下的投放可行域,并以落点速度和精度为优化条件,建立目标优化函数,找到最优投放点。计算结果表明,在解算出的最优投放点实施空投,精确性、可靠性较高,在随机风场低空空投任务中能够取得理想空投效果。To satisfy the technical requirement of precision and reliability,this paper presents a method for calculating the optimal release point.By building the releasing-landing database under the standard conditions and the neural network fitting algorithm,the feasible areas of releasing under all conditions are trained,and the objective optimization function is established,which is used to find the optimal release point.The calculating result shows that this method is of high precision and reliability,and it can achieve ideal effect in airdropping mission.
