【摘要】 为了研究某新型火箭武器燃气流对射击准确度的影响,文中分析了在较小的发射间隔时,前弹燃气流对后弹的作用力。建立了燃气流冲击力模型,以六自由度刚体弹道模型为基础,建立了火箭弹的外弹道方程,最后基于蒙特卡罗法建立了仿真系统并进行了仿真计算。仿真结果表明燃气流对射击准确度具有一定的影响。更多还原

【Abstract】 In order to study the influence of combustion-gas flow of some new antiaircraft rocket system to fire accuracy. acting force of combustion-gas flow of front projectile to trajectory of back projectile was analyzed in very short interval. The model of combustion-gas flow force was then built up.Then the external trajectory equation was established based on the six-degree-of-freedom external trajectory model.Finally,the simulation system was set up and a numerical simu- lation was carried out by using the method of Monte-Carlo.The simulation results showed that the combustion-gas flow could affect fire accuracy to a certain extent.更多还原
