| Abstract: |
| Large LOX/LH2 engine is the first choice of the upper stage power system for heavy launch vehicle. In order to obtain the interrelated material selection and manufacturing technology experience, the main technology scheme of foreign large LOX/LH2 thrust chamber was reviewed. The developing status and directions of material selection and manufacturing technology for injectors, combustion chamber and nozzle extension were included. The research results can provide some guidance for the optimization design of 200t LOX/LH2 thrust chamber for heavy launch vehicle. |
