电磁线圈发射舰载反鱼雷鱼雷拦截概率仿真分析

Intercept Probability Simulation and Analysis of Electromagnetic Coil Launched Anti-torpedo Torpedo

电磁发射技术具有动能大、效率高、能量可控等特点,可用于发射舰载反鱼雷鱼雷。针对电磁发射反鱼雷鱼雷拦截概率问题,在典型作战态势下,分别建立了多级电磁线圈炮发射模型、本舰的运动数学模型、基于“线导+声自导”的来袭鱼雷弹道模型、反鱼雷鱼雷直接拦截弹道模型,并给出了反鱼雷鱼雷对来袭鱼雷的捕获及拦截条件,采用MATLAB对电磁发射反鱼雷鱼雷作战的拦截概率进行了仿真及定量分析。仿真结果表明,与传统发射方式相比,采用电磁发射可提高反鱼雷鱼雷拦截概率,且该发射方式可使拦截点远离本舰、减少作战耗时,提高作战安全性。

The electromagnetic launch technology,featuring high kinetic energy,high energy conversion efficiency and energy controllability,can be applied to launching shipborne anti-torpedo torpedoes.Based on a typical combat situation,the launching model of a multi-level electromagnetic coil gun,the mathematical model of the warship′s motion,the trajectory model of a wire-guided and acoustic homing attacking torpedo,the direct intercept trajectory model of the anti-torpedo torpedo are established in order to study the intercept probability of the electromagnetic launched anti-torpedo torpedo.And the conditions of acquisition and interception are given.MATLAB is used to simulate and quantitatively analyze the intercept probability of the electromagnetically launched anti-torpedo torpedo.The results show that,compared with traditional launching mode,the electromagnetic launching method can improve intercept probability;the electromagnetically launched anti-torpedo torpedo can intercept the attacking torpedo far away from the warship to improve the survival probability.
