China News Service, Xi’an, December 10 (Zhang Yichen, Yang Yingqi) The reporter learned from the Sixth Academy of China Aerospace Science and Technology Corporation (hereinafter referred to as the Sixth Academy of Aerospace Science and Technology) that it will take eight years to develop a 500-ton liquid oxygen kerosene engine. The Type 9 pumped liquid rocket engine, represented by the 100-ton supplementary combustion circulating liquid oxygen liquid hydrogen engine, supports the implementation of major space missions such as manned moon landing, deep-space exploration, and space-to-earth repeated use of transportation systems.

　　At 8:11 on December 10th, Beijing time, the Long March 4B carrier rocket was ignited and lifted off at the Jiuquan Satellite Launch Center. It successfully put the Shishi-6 Group 05 satellites into the scheduled orbit, and the launch mission was a complete success.

At the same time, the number of launches of China's Long March series of carrier rockets was refreshed to 400 times.

　　From Dongfanghong-1 playing the prelude to China's space exploration, to manned spaceflight and Beidou networking, to Chang'e lunar exploration and Mars exploration, a series of liquid-powered products developed by the Sixth Academy of China Aerospace, constantly recommending the Long March series of carrier rockets to fly to the sky .

　　Experts from the Sixth Academy of Aerospace said that with the continuous development of the new generation of Long March series of carrier rockets, the new and old rockets will be fully replaced, and China's carrier rocket capabilities will once again achieve a new leap.

At the same time, China's space transportation methods will also achieve major breakthroughs from one-time use to repeated use, from a single space transportation to a combination of space transportation and space operations.

　　"Develop aerospace and power first." Since the first flight of the Long March 1 rocket on April 24, 1970, the Long March series rockets achieved 400 launches on December 10, 2021, reflecting the fact that China's aerospace industry has grown from nothing, from small to large. , From weak to strong.

　　"In 2021, Liquid Power has entered a new journey to fully support the building of a space power. In the face of the new requirements of building a space power, liquid power products must achieve excellence." said Wang Wanjun, the president of the Sixth Academy of Aerospace Engineering.

　　According to reports, the "Long March" series of rockets have gone from normal temperature propulsion to low temperature propulsion, from series to parallel, from low orbit to high orbit, from "one arrow with one satellite" to "one arrow with multiple stars", from launching artificial earth satellites. In the technological process of launching manned spacecraft and space probes, it now has the carrying capacity to launch different orbits of low, medium and high, and different types of loads. It has all aspects of thrust, success rate, launch frequency, orbit accuracy and adaptability. Reach the world-class level.

　　The Sixth Academy of Aerospace Engineering stated that, on the one hand, the successful application of the 500-ton liquid oxygen kerosene engine will increase the carrying capacity of China's carrier rocket from the current 20-ton carrier by four to five times, reaching the 100-ton class.

On the other hand, centering on the requirements of "reliable, convenient, and cheap" access to space, the development of reusable engines has been carried out to support subsequent deep-space exploration at greater distances.

In the future, the Long March series of carrier rockets will also start more "new Long Marchs" and realize new "flying dreams".
