China's new generation of manned launch vehicle engine development achieved a major breakthrough

According to the Sixth Academy of China Aerospace Science and Technology Group, China's first high-altitude pump rear-swing high-thrust liquid oxygen kerosene engine recently conducted a 300-second long-distance test, achieved successfully.

The engine has the characteristics of high specific impulse and low starting inlet pressure, and will be used in the secondary power plant of China's new generation of manned launch vehicles. It is reported that since September 28, this engine has completed three tests for a total of 650 seconds.

The main working characteristics of this type of engine have been successfully obtained in three trials. All the indicators of the engine basically meet the overall requirements, marking a breakthrough in the key technology of this type of engine and laying a solid foundation for the smooth development of China's future generation manned rocket project.
