摘要

摘要: 锂/六氟化硫热源的启动技术是制约闭式循环动力系统在无人水下航行器应用的关键技术之一。文中根据锂/六氟化硫启动过程的特点, 确定了启动剂的基础配方, 制备了小尺寸启动剂样品, 开展了启动剂的点火性能试验和小功率锅炉反应器快速启动试验。试验结果表明, 启动剂释放的热量在几秒内实现了金属锂的液化且锂液温度超过400℃, 点火后合理控制氧化剂和冷却水的进入时间次序和流量匹配方式可实现锅炉反应器的持续稳定工作。

Abstract: The start-up technology of a lithium/sulfur hexafluoride heat source is one of the key technologies restricting the application of closed-cycle power systems in unmanned undersea vehicles. According to the characteristics of the lithium/sulfur hexafluoride start-up process, the basic composition of the start-up reagent is determined, the small-size start-up reagent sample is prepared, and the ignition performance test of the start-up reagent and the fast start-up experiment of the small-power boiler reactor are carried out. The test results show that the heat released by the start-up reagent liquefied lithium metal in a few seconds and the lithium liquid temperature exceeded 400℃. Reasonable control of the entry time sequence and flow matching mode of the oxidant and cooling water after ignition can realize continuous and stable operation of the boiler reactor.
