    Abstract
  • To establish the analytic formula of the hitting probability for sub-launched torpedo with a predetermined encounter situation, the geometric analysis method is adopted. Firstly, the influence of encounter situation on the hitting probability of sub-launched torpedo is analyzed, and the general calculation model of the torpedo hitting error in the two-time rotating angle shooting with different homing modes are established. On this basis, the analytic formula of torpedo hitting probability is es-tablished, and the values of model parameters are analyzed. Finally, based on the calculation results of examples, the torpedo hitting probability curves are analyzed quantitatively, the analytical calculation result and the simulation calculation results of torpedo hitting probability are compared, the feasibility of the analytical calculation method and the correctness of the model are verified. The influence of different elements errors on torpedo hitting result is compared and analyzed based on torpedo one-time and two-time rotating angle shooting.
