通过对弹丸外弹道计算方法的分析,针对在弹道计算过程中,很难预知弹丸实时的飞行姿态的问题。文中应用空气动力学软件对弹丸空气动力仿真分析,得到了不同马赫、不同攻角下的动力参数,形成离散数表。再由运动学软件对弹丸整个飞行过程模拟计算,直观地得到了弹丸在整个外弹道的稳定性情况、飞行轨迹及各弹道诸元。与实验数据相比较,误差不大,验证了分析的正确性,为复杂的弹丸外弹道模型计算提出了新的方法。

Based on the analysis of exterior ballistic calculation method, in trajectory calculation process, it is difficult to predict real-time flight attitude problem. In this paper, the air dynamics software was applied to projectile aerodynamic simulation analysis, dynamic parameters under different Mach number and different angles of attack were got for discrete tables. The kinematics software on projectile throughout the flight simulation, direct the projectile in the exterior ballistic stability, flight trajectory, and the trajectory. Compared with the experimental data, the error is not serious. The correctness of the analysis was verified, the new method can be used for complex exterior ballistic model computation.
