航空子母炸弹弹道特征数的处理方法

THE METHOD DEALING WITH BALLISTIC CHARACTERS FOR AIR-DROPPED SHRAPNAL BOMBS

航空子母炸弹的母弹和子弹的外形结构均比较特殊。母弹从载机上落下后,受飞机扰流的影响,其运动参数发生交化。子弹从母弹弹体弹出后,其初始攻角一般均很大,子炸弹的摆动现象较严重。所以,它们的阻力特征与一般弹丸不一样。本文分析了航空子母炸弹的弹道特点,针对其独有的特殊性给出了不同的处理方法。为分析研究航空子母炸弹的运动规律和编制投弹表探明了一条可靠的捷径。

The structure of Air-dropped shrapnel bombs which include canisters and shots is complicated. Afar leaving an aircrft, the shrapnel parameters of motion are changed by disturbance of the aircraft. Ejecting from the canister, the initial yaw angle of shots is usually large and the rotation problem is severe. The drag properties of shots are different from conventional projectiles. Analyzing ballistic characteristics and particular phenomena of air-dropped shrapnels, the paper presents some solution methods. They are useful for the study of motion about shrapnel bombs and the compilation of bomb tables.
