The study on firing advance angle and start-up opportunity of the initiative acoustic homing equipment of dual-speed acoustic homing torpedo

The firing advance angle and start-up opportunity of initiative acoustic homing equipment of dual-speed torpedo are the important launching parameters, in this paper, the anti-submarine characteristic of dual-speed acoustic homing torpedo in target searching section is analyzed firstly, a conception of advance angle range and the principle of start-up opportunity of acoustic homing equipment are presented according to speed changing in straight-running segment, then the calculation model is structured based on the course stay the same before and after the torpedo speed changing, Finally the mathematical model is emulated using the iterative method and the result show that the model is reasonable and convenient.
