针对舰船弹库裸装导弹在弹药舱中意外点火，向导弹发动机尾喷管燃气射流区域注射高压水降温问题进行研究。通过对控制体入口和出口简化，采用参数比拟法，建立考虑水射流破碎的注水流量与燃气温度计算方法，并用算例进行计算分析。本方法可为弹库注水系统设计提供理论依据和计算方法。
In this paper, the problem of accidental ignition of a Packless missile in missile depot of warship and injection of high pressure water into jet area of tail nozzle of the missile engine to cool it down is studied. By simplifying the inlet and outlet of the control body and using the parameter comparison method, the calculation method of water injection flow and gas temperature considering the water jet breaking is established, and the calculation and analysis are carried out with the example. This method can provide theoretical basis and calculation method for the design of ammunition depot water injection system.
