Abstract:
The 500 tf class high pressure stage combustion LOX/kerosene rocket engine is the main power for next-generation rocket.The engine will greatly improve the technical level of rocket engine and provide a strong power for space development in China.In the general design of high pressure stage combustion cycle, swinging after pump and two thrust chambers are adopt.The engine has the characteristics of innocuous, high performance, high reliability, adjustable thrust and mixture ratio, and convenient for use.The key technologies should be breached,including stepped starting, health management, swingingafter pump, high-power high-efficiency turbo-pump, high-pressure high-efficiency high-flow-rate combustion subassembly, high-pressure high-flow-rate regulator and low-temperature valve, new product technics and new test.Main development of the engine is that, the design and production of the engine, many experiments, half system tests and production of the first engine have been finished.The key technologies were validated, that lay a foundation for the intending development of the engine.
