本文是从工程设计计算需要的角度来考虑,在比较全面地考察了各种扰动因素影响的情况下,导出了箭、弹起始扰动统一的理论分析和计算公式。对于旋转稳定和尾翼稳定的枪、炮弹丸及炮射火箭弹进行起始扰动的计算分析,估计起始扰动对射弹散布的影响,研究起始扰动形成的主要原因,探讨提高射击密集度的可能途径等,具有一定的实际意义。 This article is from the perspective of engineering design and calculation needs to consider, in a more comprehensive examination of the impact of various disturbance factors, derived a unified theoretical analysis and calculation formula of the initial bounce of the arrow and bombs. In this paper, the initial perturbations of guns, projectiles and projectiles are analyzed and calculated. The influence of initial perturbation on the projectile dispersion is estimated. The main reason for the initial disturbance is studied. Possible ways, has a certain practical significance.
