Departent of Weapon Engineering, Naval Engineering University, Wuhan , China; th Unit, The People s Liberation Ary of China, Qingdao , China) Abstract: A shift point shooting ethod of an anti-subarine torpedo is proposed to effectively attack a aneuverable subarine, i.e., when an anti-subarine torpedo is launched to iaginary point, the point has shifted certain range and angle relative to the expected hit point. Accordingly, atheatical odels of lead angle, torpedo oveent, and subarine aneuver are established, and the solutions to the shift range and shift angle are offered. Further, the optiized shift ranges and shift angles for different warfare states are calculated. Keywords: anti-subarine torpedo; aneuverable target; shift point shooting ethod 0 ÑÁ Œ ê ¼ [1-2] k œ œ Ñ, œ q œ q Ð, é q s ƒ æ e œ ê l, ê l å, œ ì, Á å ê l, s œ ž [3-5], ϕ n ê é, æ Á Œœ, Á å ênœ ý ÿ Ïé k, Á ê,, œ, e l œ ê, k Œé 1 zç Ç ê Œ œê {, j e å D 0 Q 0 ká ê ê, { ; ~v (1971-),, Ï, ø, Ðq s. 464 Torpedo Technology
