Abstract

Abstract: A design scheme of push-pull cylinder type torpedo launcher for warship is proposed to solve the problems about long launch preparation time and poor support capability of ship-launched torpedo. Simulink and Adams co-simulation method is used to establish a dynamic model of high pressure air launching process of the launcher for simulation analysis. The simulated results were verified by the scaled prototype experiments. The simulated and experimental results show that, when the gas pressure in cylinder is 25 MPa, the peak pressure of push-pull cylinder is 9.3 MPa, the maximum contact force between the parts in the launcher is 66.6 kN, the muzzle velocity of torpedo is 14.7 m/s, the maximum acceleration is 236 m/s², and the time of launching is 0.14 s.
