摘　　要：不同弹箭的飞行弹道特性对指导外弹道设计、构建一些弹道判据等有重要意义.文章基于弹箭飞行动力学方程组及合理简化,对旋转稳定弹飞行弹道上的质心加速度变化、旋转角加速度变化等动力学弹道环境特性状况,以及旋转圈数同飞行距离的关系等进行了研究,分析得出了它们沿飞行弹道上的变化规律,并建立了相关关系表达式和判据.对两种型号的旋转稳定弹进行外弹道仿真计算,验证了结论的正确性.这些空气弹道特性的研究结果,将对今后开展一些新型弹箭方案研究、弹药信息化利用、控制飞行与安全性设计等提供技术支持.The flight ballistic characteristics of different projectiles and rockets are of great significance for guiding external trajectory design and constructing some ballistic criteria.In this article,the dynamic ballistic environment characteristics and the relationship between the rotation number and flight distance were studied based on the dynamic equations of projectiles and rocket flight with reasonable simplification to analyze the variation of the mass acceleration,rotation angular acceleration,and so on the flight ballistic condition of a spin-stabilized projectile.The variation patterns along the flight ballistic trajectory were analyzed,establishing relevant relationship expressions and criterion.Finally,carrying out simulation calculations for external ballistic trajectory of two types of spin-stabilized projectiles,the correctness of the conclusion was verified.The research results show that the air ballistic characteristics can provide a technical support for future research on new projectiles plans,ammunition information utilization,control flight,safety design and so on.
