Inner Trajectory Modeling and Simulation of Hydraulic Energy Accumulated Torpedo Launcher

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.
