对某水下气动发射装置进行了理论分析,研究了其内弹道特性。利用数学建模方法对发射过程进行了建模并对内弹道性质进行了计算。对影响内弹道性能的3个主要参数:武器运动的初始阻力、发射阀最大开启面积和发射气瓶初始充气压强进行了分析。计算结果表明:发射管最大膛压的主要影响参数为武器运动初始阻力;而武器出管速度的主要影响参数为发射气瓶初始充气压强和发射阀的最大开启面积。
A certain underwater aerodynamic launch device is analyzed theoretically and its internal ballistic characteristics are studied. The mathematical model was used to model the launch process and calculate the internal ballistic properties. The three main parameters affecting internal ballistic performance were analyzed: the initial resistance of the weapon movement, the maximum open area of the launch valve and the initial inflation pressure of the launch cylinder. The calculation results show that the main influence parameter of the maximum chamber pressure of the launch tube is the initial resistance of the weapon movement. The main influencing parameters of the tube speed of the launch tube are the initial inflation pressure of the launch cylinder and the maximum opening area of the launch valve.
