在对高原条件分析的基础上,对火炮武器弹丸在高原上的陀螺飞行稳定性、动态飞行稳定性、转速衰减规律、章动规律、动力平衡角、射程、偏流以及地面密集度等弹道特性进行了理论研究,通过六自由度弹道计算,得到了各主要弹道参数随海拔高度的变化量.结果表明,随着海拔高度的增大,弹丸的陀螺稳定性和动态稳定性增强,动力平衡角和偏流明显增大,地面密集度有所提高.

Based on the analysis of the plateau conditions, the ballistic properties of artillery projectiles were researched theoretically including gyroscopic stability, dynamic stability, spin rate law, nutation law, the trim angle of yaw at the dynamic equilibrium, range, drift and ground dispersion. By the computation of six-degree-of-freedom ballistic model, the quantitative relations of many main ballistic parameters to altitude above sea level were obtained. The results show that the higher the plateau, the higher the gyroscopic stability and dynamic stability are, and dynamic balancing angle and drift increase obviously, and ground density improves.
