摘　　要：针对某舰载多管火箭炮占甲板空间大、在方位和高低上存在发射死角等问题,提出了新型的火箭弹垂直发射系统。为验证发射系统可行性,应用FLUENT软件对弹的发射过程进行了数值模拟,得到了发射装置内燃气流场特性和变化规律。结果表明,发射过程中装置底部空腔压力较小,对发动机安全运行不构成威胁,并且底部压强对弹体产生的增程力也不明显,影响可忽略,最后和试验数据进行了比较验证,为装置的改进提供了试验和理论依据。According to the problem that the ship-brone MLRS which takes up large deck space and existences blind angle on the direction and height,design a new type of rocket vertical launching system.To verify feasibility of the launch system,used the FLUENT to simulate the launching process of the rocket,and got the jet flow field characteristics and change rules of the bottom of the device.The results show that the pressure of the bottom of the device is small in the process of launching,which doesn t threaten the safe operation of the engine,and the increasing force is inconspicuous.Comparing the simulation results and the experiment data in the end,which provides test and theoretical basis for the optimization of the launcher.
