本文针对某空投鱼雷海上定型试验中后期弹道出现的小幅度波动搜索现象,从控制系统、全雷总体和制导大系统分别进行了实航记录和数学仿真计算及分析。结果表明,虽然在上限附近弹道波动对搜索目标有一定影响,但本型鱼雷产生波动搜索目标为小概率事件,对使用影响不大。 In this paper, aiming at the small amplitude fluctuation search phenomenon in the late ballistic test of an aerial torpedo test, the real navigation record and mathematical simulation calculation and analysis are carried out from the control system, the total mine total system and the guidance large system respectively. The results show that although the fluctuation of the trajectory near the upper limit has an impact on the search target, the target of the fluctuation search of this torpedo is a small probability event, which has little effect on the use.
