Verification Technology for the Main Engine of China's Manned Lunar Rocket to Complete Flight Tasks | Engine | Lunar Landing
The reporter learned from the Sixth Academy of Aerospace Science and Technology Group that the main engine of China's manned lunar rocket, Long March 10, completed another ignition test yesterday, verifying all the requirements of the rocket flight mission for the engine, providing strong support for the solidification of engine technology status, establishment of product technology baseline, and improvement of reliability.
The engine used in this test run uses advanced liquid oxygen kerosene as fuel, which is improved and iterated from the high thrust liquid oxygen kerosene engine used in new generation launch vehicles such as the active Long March 5. The thrust reaches 130 tons and will be used for the core stage and booster of the Long March 10 rocket used for manned lunar landing in China.
Researcher Zhou Xianqi from the 165 Institute of the Sixth Academy of Aerospace Science and Technology Group: Based on today's test drive, this engine has successfully met the relevant test requirements, assessed the engine's starting, shutdown, and smoothness in high and low operating conditions, and all relevant parameters have been obtained.
It is reported that in the development process of the engine, many new materials, processes, and technologies have been applied. Scientific researchers have successively overcome key technical difficulties such as engine start and stop timing, large-scale continuous variable thrust of the engine, and long service life and high reliability of the engine, laying a solid foundation for the next step of engine development.
Researcher Zhou Xianqi from the 165 Institute of the Sixth Academy of Aerospace Science and Technology Group: After the completion of this engine test today, we will conduct several high-altitude simulation tests in the second half of the year to ultimately determine the relevant performance and parameters of this engine, and make the contribution that astronauts should make to the development of the main power engine for manned lunar landing.
