The pressurization system based on the high-temperature phase change matter comprises a storage box, a pressurization component, a to-be-pressurized component and a high-temperature fuel gas pipeline, the to-be-pressurized component, the pressurization component and the high-temperature fuel gas pipeline are sequentially and adjacently arranged, the high-temperature fuel gas pipeline communicates with an afterburning combustion chamber, a heat exchange device is arranged in the pressurization component, and the heat exchange device is communicated with the afterburning combustion chamber. According to the high-temperature fuel gas pressurizing device, the substance which is easy to sublimate and stored at the normal temperature is adopted as the pressurizing working medium, is stored in a solid state, and sublimates into a gas state by absorbing heat of the high-temperature fuel gas pipeline during working so as to pressurize a part needing to be pressurized. According to the system, the thermal protection problem caused when high-temperature fuel gas is directly used for pressurization and the problem that a special-shaped metal storage box is difficult to machine and manufacture are solved, application of a non-metal storage box in the high-temperature fuel gas pressurization system can be achieved, meanwhile, the weight and the size of a propelling system can be effectively reduced, and the system has the advantages of being reliable, safe and easy to maintain.
本发明提供了一种基于高温相变物质的增压系统,包括贮箱、增压部件、待增压部件以及高温燃气管路,所述待增压部件、增压部件以及高温燃气管路依次相邻布置,所述高温燃气管路与补燃燃烧室连通,所述增压部件内部设置有热交换装置,且容纳有增压工质,所述增压工质的升华点低于燃气温度,本发明采用常温贮存的易升华物质作为增压工质,以固体形态存储,工作时通过吸收高温燃气管路的热量升华为气态,对需增压的部件进行增压。此系统避免了直接使用高温燃气进行增压时带来的热防护问题和异形金属贮箱加工制造困难的问题,可以实现非金属贮箱在高温燃气增压系统中的应用,同时能有效降低推进系统的重量和体积,具有可靠、安全和易维护特性。
