| 摘 要： | 针对电磁轨道炮在发射时存在初始扰动,飞行时由于速度极大引起气动烧蚀改变气动外形,因此有必要建立电磁轨道炮外弹道数学模型,分析其外弹道特性.通过分析了电磁轨道炮外弹道建模方法,建立了电磁轨道炮的外弹道数学模型.根据不同技战术指标建立初始随机概率模型,用Monte Carlo方法对电磁轨道炮的外弹道特性进行仿真.仿真结果给出了一定散布范围内的高低概率误差和方向概率误差,对电磁轨道炮武器系统设计指标的提出有参考价值.

| Abstract: | It is necessary to establish exterior trajectory models for analyzing exterior trajectory characteristics of electromagnetic railgun,because of the disturbance during launch,aerodynamic heating and ablation by hypervelocity. The modeling method is analyzed for exterior trajectory models of electromagnetic railgun and the exterior trajectory models are established. An initial random mathematic model is established according to definite index. Based on Monte Carlo method,exterior trajectory characteristics ar... |
