摘要

摘要: 浮囊能否可靠充气, 直接影响到鱼雷的安全回收, 为深入了解浮囊充气机理, 根据热力学定理建立了浮囊充气过程模型, 对气瓶排气、浮囊充气过程进行了仿真计算, 获得了充气过程中浮囊体积、充气流速、气瓶压力和浮囊受力等参数的变化规律。通过鱼雷带速停车充气过程仿真, 获得了临界深度下浮囊涨满、雷速变化等细节过程。仿真结果表明, 浮囊涨满时间、气瓶剩余压力等参数与试验数据相近, 鱼雷带速停车后雷速、航深等参数规律与试验结果相符, 该浮囊充气过程模型可为上浮装置的工程设计提供参考。

Abstract: Reliability of inflation process of a torpedo inflatable collar directly influences the safe recovery of the tor-pedo. In order to understand the inflation mechanism of a torpedo inflatable collar, a theoretical model of inflation process of a torpedo inflatable collar is built to simulate the tank exhausting and torpedo inflatable collar inflation proc-esses based on the thermodynamic law. The variation rules of the parameters, such as the volume of inflatable collar, the inflation velocity, the tank pressure and the force on inflatable collar during inflation process, are obtained. The detail processes of torpedo speed changing and inflatable collar filling under critical depth is gotten by simulation of torpedo inflation process in the case of torpedo stop with speed. Simulation results illustrate that the parameters such as inflat-able collar inflation and residual gas pressure, as well as the variation rules of torpedo speed and depth, show good agreement with the experimental data. The proposed model may provide a theoretical tool for design of torpedo buoy-ancy equipment.
