为了研究某型发射装置在发射过程中的流场特性，建立了该发射装置的弹道模型，耦合其发射弹道模型并利用Fluent动网格技术，对包含弹运动的发射装置炮口、炮尾同时有火药气体喷出情况下复杂流场进行了数值仿真，仿真得到了发射装置在整个发射过程中流场的形成与发展变化；并对炮口与炮尾流场的变化规律进行了详细的分析，通过监测炮尾、炮口相关区域的冲击波，得到整个过程相应区域的超压值，对于预测冲击波在相关区域产生的危害具有指导意义。

To study the characteristics of flow field of the launching device,we established the model of the device. Flow field of the device was simulated which couPled with the ballistics,and the Projectile was set by Fluent dynamic mesh,and got the change course of flow field of the launch which Projectiles move﹣ment during the whole Process. Then we analyzed the rule of flow field and monitored the shock﹣wave of the launch areas,it can Provide guidance for research harm of the shock﹣wave.
