摘要: 液压蓄能式鱼雷发射装置以其低发射噪声、无舱室增压等优点备受各国海军青睐。为研究该型鱼雷发射装置的内弹道特性, 该文在其结构及发射原理基础上, 通过合理简化及假设建立了该装置发射过程的内弹道模型,并在MATLAB/Simulink环境下进行了仿真计算。仿真结果表明, 建立的内弹道模型能基本反映该装置的内弹道特性, 为装置的工程设计提供了依据。要使其内弹道性能满足要求, 应结合该装置的具体战技指标来确定装置的结构参数及初始能量储备。Abstract: For its low launching noise and absence of increasing pressure in chamber, the hydraulic energy accumulated torpedo launcher has held navies′ interest around the world. In this paper, to research the inner trajectory characteristic of the launcher, an inner trajectory model for the launching course is built on the basis of the structure and launching theory by proper simplification and hypothesis. Simulation is performed with MATLAB/Simulink, and the result shows the validity of the model. Tactical and technical indexes of the launcher should be considered in determination of its structure parameters and initial energy storage to meet the requirement for inner trajectory characteristic.
