| 摘 要： | 本文利用简化的刚体弹道方程分析了各种空气动力系数对于动力平衡角的大小及其曲线形状的影响,并在此基础上论述了动力平衡角对于射程及偏流的影响。通过计算表明,由动力平衡角产生的马格努斯力有时对射程会产生较大的影响。此外由马格努斯力矩等因素造成的动力平衡角曲线形状的变化,在某些情况下通过升力对射程也会产生较大的影响。

| Abstract: | Equations of motion for a simplified rigid trajectory are utilized to analyse the aerodynamic factors that affect the amplitude of the dynamic equilibrium yaw and the shape of its curve. These factors have different effects on range and drift. The results show that Magnus force produced by the dynamic equi- librium yaw, sometimes has a significant effect on the range. Furthermore, the change of the curve of the dynamic equilibrium yaw caused by such factors as the Magnus moment etc., in some cases, can also produce a considerable effect on the range. |
