Abstract: In order to lay foundation for modeling and simulation of operation problems such as torpedo attacking, torpedo operation application and torpedo operation effectiveness analysis, etc., the model of submarine torpedo-launching is built in the way of qualitative analysis and classical mathematics. As an important composition of submarine torpedo-attacking, torpedo-launching mainly means the course from torpedo out-tube to hitting target or voyage end, which is between the stage of “controlling weapon launching” and “observing attack effectiveness” during the whole torpedo-attacking course. Through analyzing the seven-stage trajectory process of torpedo-launching, the target detecting model and acoustic homing range model of acoustic homing torpedo are built. The wake characteristics model, the wake area geometrical model and the wake detecting model of wake homing torpedo are established. The target geometrical model, torpedo hitting judgment model and torpedo rapid hitting judgment model are also set up.

Key words: submarine, torpedo launching, trajectory process, finding model, hitting judgment model
