An Analytic Computational Method of Hitting Result for Submarine-Launched Torpedo

In order to calculate hitting result with analytic computational method for submarine-launched torpedo,geometrical analysis is adopted.The paper transforms the shooting models with various homing modes into a general equation according to the trajectory of submarine-launched torpedo,after analyze analytic relation of TMA(course,speed,launch range) and torpedo hitting result,the paper builds analytical calculation method of hitting result.Based on this,the paper analyses the effect of TMA error to torpedo hitting result under different Guidance mode(straight running,acoustic homing,wake homing).Example illuminates the feasibility and validity of this calculation method.
