The invention discloses a closed combustion chamber suitable for an unmanned underwater vehicle and a using method of the closed combustion chamber, and relates to the technical field of thermal power of underwater vehicles. According to the invention, the upper end cover, the lower end cover and the outer shell form an outer shell of the combustion chamber, the three parts are detachably connected, and the outer shell is provided with a cooling water channel. The outer shell, the metal lining and the inner shell form a three-layer sleeve structure, the resistance wire is arranged on the inner side wall of the inner shell, and the wick is arranged in an inner cavity of the inner shell; the spark plug, the electrode and the oxidizing gas nozzle extend into the inner shell from the upper end cover. The method comprises the following steps: placing solid metal fuel at the bottom of an inner cavity of a combustion chamber, heating the metal fuel through a resistance wire, and controlling the power of the combustion chamber by adjusting the input quantity of oxidizing gas. The device has the advantages that the device can be quickly started, the wick can be quickly replaced, the nozzle is not easy to block, low-power operation can be realized and the like, and the requirement of low-speed cruise of the UUV can be met.

    一种适用于无人水下航行器的密闭燃烧室及其使用方法,涉及水下航行器热动力技术领域。本发明中,上端盖、下端盖和外壳体构成燃烧室外部壳体,且三部分之间可拆卸连接,外部壳体开有冷却水通道。外部壳体、金属衬套和内壳体形成三层套筒结构,电阻丝布置在内壳体的内侧壁上,吸液芯布置在内壳体的内腔中;火花塞、电极和氧化气体喷嘴由上端盖延伸至内壳体的内部。上述方法如下:将固态金属燃料置于燃烧室内腔底部,通过电阻丝加热金属燃料,通过调节氧化气体输入量控制燃烧室功率。本发明具有能够快速启动快、快速更换吸液芯,喷嘴不易堵塞、可以低功率运行等优点,能够满足UUV低速巡航的需求。
