Abstract:
In order to achieve the rapid verification of key technologies of hydrogen peroxide/kerosene thrust chamber, the design and test of thrust chamber based on 3D printing rapid manufacturing was conducted. Firstly, according to the design index, the design of hydrogen peroxide/kerosene thrust chamber was completed by utilizing the advantages of 3D printing, such as fewer parts, high connection strength and light structural weight. Then, the commercial software Fluent was used to perform the rapid numerical simulation of combustion on the design scheme, and the pressure, temperature, streamline, and mass fraction of each component in the thrust chamber under the design conditionwere obtained. The combustion performance was analyzed and the optimization of the design scheme was completed. Finally, the performance of the thrust chamber was evaluated through the long-term hot test. The results show that the 3D printing thrust chamber has high structural reliability, good cooling performance, high combustion performance, and meets the design requirements. Compared to the traditional mechanical processing techniques, it shortens the development cycle by 50%, reduces manufacturing costs by 40%, reduces the number of parts by 50%, and reduces weight by 20%. At the same time, it fully shows the advantages of the 3D printing technology in the key technology verification stage of the thrust chamber, such as short cycle, low cost and high reliability.
