尾流自导鱼雷极限射击范围的数学描述

MATHEMATIC DESCRIPTION OF UTMOST FIELD OF FIRE ABOUT WAKE-GUIDED TORPEDO

基于尾流自导鱼雷弹道的分析,得出了该雷在满足尾流进入角条件下可分为一次转角射击和二次转角射击2种射击模式,建立了与之相应的极限射距、极限射击圆和最小允许射击圆数学模型.在对模型进行数学分析后,得出该鱼雷的射击范围为其极限射击圆之内与最小允许射击圆之外的相交部分.

Based on the analysis of the trajectory about wake-guided torpedo, the attack mode that can be divided into turning the cape attack once and turning the cape attack two times is considered from the foundation that the torpedo can enter and track the wake of ship at some entry angle. Three primary mathematic models are established which include utmost distance of fire, utmost field circularity of fire and least field circularity of fire, and analyzed by the way of math. The field of fire about wake- guided torpedo is the intersection field which is formed by the field out of least field circularity of fire and the field inside utmost field circularity of fire.
