直升机空投鱼雷的入水点散布误差是影响鱼雷发现概率的重要因素,对其进行分析研究有助于客观地评估空投鱼雷的作战效能。在使用成熟弹道模型模拟空投鱼雷空中弹道的基础上,通过多元非线性回归分析的方法计算出了空投鱼雷散布规律的模拟公式;并据此仿真分析了直升机运动态势和风速、风向对空投鱼雷入水点的影响。

英文摘要：

Dispersion errors of helicopter airdrop torpedoes water entry point have important effects on torpedodetection, so it＇s helpful to evaluate airdrop torpedoes operational effectiveness objectively by analyzing its dispersion errors. On the basis of airdrop torpedoair trajectory which is simulated by mature trajectory models, the simula-tion formula of airdrop torpedon dispersion law is calculated by multivariate nonlinear regression analysis. Then, the influences of helicopter’s movement situations and wind speed and direction on airdrop torpedo’s water entry point are simulated and analyzed.
