Fast science and technology news on June 2The 130-ton pump liquid oxygen kerosene engine, the main engine of China's manned lunar landing rocket developed by the sixth Academy of China Aerospace Science and Technology Group, has recently successfully completed its sixth test run since it came to power.

So farThe cumulative test time of this engine has reached 3300 seconds, setting a new record for a single 100-ton engine in China.

This engine is the first developed product after entering the parallel stage of development and delivery. it shoulders the important task of testing the life limit for the first time after the technical state of the product is solidified.

Since the development of 130-ton pump rear pendulum liquid oxygen kerosene engine, a number of technical weak links have been exposed in the limit test. The sixth Institute has taken effective improvement measures in time to improve the essential reliability of the product.

As the main engine of China's future manned lunar landing rocket, it needs to have higher comprehensive performance and reliability.The longest test run record of the engine is refreshed within half a year, and the working time is more than 10 times of the task time, which verifies the reliability of the engine again.

It is worth mentioning that on May 30th, ldquo; Tongchuan Test Center of China Aerospace New Power & rdquo; Asia's largest thrust test stand, No.2 station test stand, was a complete success.

This is another major achievement achieved after the successful test run of the workstation test stand on April 24, marking the beginning of the year.The dual-station test bench of Asia's largest thrust liquid rocket engine in the sixth Institute has formed a test capacity of 700 tons of basic thrust.

The test products of this test stand are85 ton open cycle liquid oxygen kerosene engineIt is the first engine of the sixth Academy & ldquo; Nine & rdquo; to be put into engineering application, and it is also an engine tailor-made for commercial spaceflight. it successfully made its maiden flight on the Tianlong-2 liquid rocket of Tianbing Technology, a private aerospace enterprise, on April 2 this year.

On May 29, the China manned Space Engineering Office announcedThe lunar landing phase of China's manned lunar exploration project has been launched, and a Chinese man will land on the moon for the first time by 2030.

The successful completion of the 700-ton liquid rocket engine test-bed, the largest dual station in Asia, marks a major breakthrough in China's liquid rocket engine infrastructure construction and a substantial improvement in its test capability. it will effectively ensure the smooth implementation of China's manned lunar landing, heavy carrier rockets, deep space exploration, space infrastructure construction and other major projects, and provide strong support for speeding up the construction of a space power.
