Abstract:
In order to meet the high-performance and high reliability requirements in development of the expander cycle liquid rocket engine, the radial turbine was adopted in the scheme selection of hydrogen turbopumps. The feasibility was preliminarily verified through 1D thermal design and 3D structure design. With CFD analysis software, the full 3D viscosity numerical simulation was completed under turbo’s design working conditions, proving that the performance could meet the qualification requirement. Two main technical problems in turbopump applications were solved through strength optimum design and axial force balance research. In combination with the results obtained in medium test and hot test, a conclusion that the radial turbine can be applied to the hydrogen turbopump of expander cycle engine was achieved.
