对重力引起的弹轴运动的讨论

ON THE MOTION OF PROJECTILE AXIS CAUSED BY GRAVITY

本文从求解攻角方程特解和动力平衡的角度,导出了动力平衡角和方程;指出了它们无本质差别,均是由重力所引起,是弹丸相对于动坐标系的动量矩守恒这一动力平衡的产物的物理实质。本文中未交待的符号意义同文献[1]。

This paper derives the yaw of repose and the Mayevsky equation from the special solution of equation of the angle of yaw and dynamic balance respectively. It shows that there exists no essential difference between them, and that they are all caused by gravity. In their physical nature they reveal the conservation of moment of momentum of a projectile relative to the moving coordinate system-a product of dynamic balance.
