为提高舰载小口径弹药的装载密度，本文基于某型高密度垂直发射系统结构，并以该系统内部燃气流场为研究对象，采用三维N-S方程对导弹发射初始过程的燃气排导性能进行研究，并对不同导流结构下的流场仿真结果进行对比分析。研究结果表明，该型发射装置设计能够满足燃气从发射筒内顺利排导的性能要求。另外，仿真计算中当导流型面与水平面夹角为45°时，排导效率达到79.98%，且内部承压状态更好。研究结果能为燃气排导系统的优化设计及高密度垂直发射系统的工程应用提供一定理论支撑和数据参考。
In order to improve the loading density of small-caliber ammunition on ships,base on the structure of a high-density vertical launch system, the gas flow field in the system was taken as the research object. Moreover, three-dimensional N-S equation was used to study the gas drainage performance during the initial launch process of the missile, and the simulation results of the flow field under difference flow structures were compared and analyzed. The results show that the design of this type of launcher can meet the performance requirements of smooth gas discharge from the launcher box. In addition, when the angle between the diversion surface and the horizontal plane is 45°, the drainage efficiency reaches 79.98%, and the internal pressure state is the better. The research results can provide some theoretical support and data reference for the optimal design of gas drainage system and the engineering application of high-density vertical launch system.
