摘要: 射击禁区是影响火箭助飞鱼雷作战使用安全的重要因素。给出了火箭助飞鱼雷射击禁区的定义及划分原则; 结合火箭助飞鱼雷水下弹道特点, 建立了火箭助飞鱼雷初始搜索段、跟踪段和再搜索段的射击禁区解算模型。仿真分析了不同因素对火箭助飞鱼雷水下射击禁区的影响, 仿真结果表明, 鱼雷自导作用距离、鱼雷航速以及目标最大航速是影响射击禁区大小的主要影响因素。最后, 从不利角度出发对火箭助飞鱼雷水下射击禁区的计算公式进行了简化。

Abstract: The definition of rocket assisted torpedo (RAT) shooting forbidden zone and the division principle are given. Accordingly, the calculation models of shooting forbidden zones in initial searching phase, pursuing phase and re-searching phase of a rocket assisted torpedo are built by considering the characteristic of its underwater trajectory. The influences of some factors on the shooting forbidden zones are analyzed via simulation, and the result indicates that the torpedo homing distance and velocity, as well as the maximum velocity of target, are the key influencing factors. Further, the expression of RAT underwater shooting forbidden zone is simplified according to infaust instance.
