China Aerospace Science and Technology Group Sixth Hospital of Sixth Hospital released three commercial aerospace liquid rocket engines on Saturday (April 22), which will effectively promote China's commercial aerospace development and improve China's ability to enter space in low -cost and large scale.

According to China CCTV News, the YF-102 engine released this time is the first open cycle of China developed by the Sixth Academy of Aerospace, and can be reused to use liquid oxygen and oil engines. Some core components are printed in 3D.It has the characteristics of high reliability and good economy, and the comprehensive performance has reached the international advanced level of similar engines.Tianlong II commercial rocket successfully achieved the first flight on April 2, depending on the help of the YF-102 engine.While it is applied to commercial rockets in the future, the YF-102 engine is also expected to help the renewal of normal temperature liquid rockets such as the Long March 2 series.

The second-level YF-102V engine derived from the first-level YF-102 engine, fully inherit the technical foundation and main component structure of the YF-102 engine, and adopts a mature production process with high reliability.

The third engine released this time-YF-209 liquid oxygen methane engine, vacuum thrust 780kn, has deep push capacity, the number of tasks is not less than three times, and the number of reuse times is not less than 30 times.Second-rate.

It is understood that the Chinese Aerospace Sixth Court will build a pulse production line with a total installed capacity of 300 commercial aerospace engines per year, and promote the better supporting the construction of the aerospace industry.
