摘要
针对转管炮发射时身管处于旋转状态的特性,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,分析了惯性力、科氏力在半约束期内对弹丸起始扰动的影响,计算得到了在半约束期运动弹丸的偏角变化规律.结果表明,半约束期内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有影响,同时弹丸偏角将随着身管转速的增加而线性增加,特别是高射速时,弹丸的偏角更大,这些可为转管武器的射击精度研究提供参考.
Based on interior ballistic theory, an attempt has been made to study the initial variable bullet dispersion of Gatling gun with a basic mathematical analysis model of bullet movement. The resulting vertical and horizontal slant angular displacement of bullet in half constraint region was presented during gun-firing, and the influence of rotor rotational speed and barrels clamp cone angle on initial ballistic dispersion were also discussed. It has been found that the rotational barrels lead to accessional bullet dispersion in contrast to conventional gun, and that the project yaw angle increases linear with rotary rate of barrels. High firing velocity （over 1200 r/m） will lead to considerable dispersion.
