转管炮旋转发射惯性对弹丸起始扰动的影响分析

研究转管炮发射时身管旋转所导致的惯性力、科氏力对弹丸起始扰动的影响,建立了同时考虑弹丸旋转惯性力和科氏力的半约束期内起始模型,估算了身管旋转发射时运动弹丸的偏角变化规律,结果表明旋转离心力和身管组半锥夹角导致的科氏力对弹丸起始扰动的影响,弹丸偏角随身管转速的增加而线性增加,特别是高转速时,由切向速度所引起的弹丸的偏角更大.这为转管武器的射击精度研究提供了参考.

Influence of Rotating Effect on Initial Bullet Disturbance In Gatling Guns

In order to study the initial projectile dispersion of Gatling guns during the half restriction region of projectile, the paper describes a basic mathematical analysis model considering rotary barrels structure, centrifugal inertial force, Coriolis inertial force and tangential velocity of projectile. The resulting vertical and horizontal slant angular displacement of projectile in half constraint region was presented during gun firing. The influence of rotor rotational speed and barrels clamp cone angle on initial ballistic dispersion were discussed. It was found that the rotational barrels should lead to accessional projectile dispersion in contrast to the other conventional gun, but the tangential velocity of barrel has more absolute effect on dispersion than the centrifugal inertial force and Coriolis inertial force of the projectile. The corresponding initial dispersion is estimated also.
