China's large thrust rocket test was successful, shocking the world.
2021-11-12
The 220-ton large thrust staged combustion cycle hydrogen-oxygen engine in China has successfully completed its first full system test, which is of great significance. The details are as follows:
Technological Breakthrough
● It marks an important progress in the research of large thrust staged combustion cycle hydrogen-oxygen rocket engines in our country. The engine adopts a closed staged combustion cycle system, featuring large thrust, high chamber pressure, and high specific impulse, among other technical characteristics. Several key technological challenges have been successfully overcome, enhancing the technological level of our aerospace engines.
● It signifies that our country's large thrust hydrogen-oxygen engine testing capability has officially formed. The test platform used in this experiment is designed with flexibility, intelligence, and digitization in mind, achieving multiple goals of "five transformations," promoting the development of testing technology, and laying a foundation for further improvement of testing capabilities and efficiency.
Promoting the Development of Aerospace Industry
● It lays a solid power foundation for the development of heavy-lift launch vehicles and reusable launchers. The staged combustion technology improves the engine's thrust and thrust-to-weight ratio, allowing heavy-lift launch vehicles to carry heavier payloads. Reusable spacecraft can also achieve significant reductions in operational costs, promoting the enhancement of our country's space launch capabilities and supporting future deep space exploration missions such as manned moon landings and Mars exploration.
● As a "green" engine, the hydrogen-oxygen engine uses liquid hydrogen and liquid oxygen as fuel, producing mainly water vapor as waste after combustion, with almost no harmful emissions, meeting the needs of sustainable development in future aerospace endeavors.
Enhancing International Competitiveness
● It has strengthened our country's competitiveness in the international aerospace field, narrowing the gap with the world's advanced ranks. This breakthrough is another significant achievement in our aerospace technology, showcasing the strength and innovative capability of our aerospace science and technology, and positioning our country more favorably in global aerospace competition.
Social Impact
● It has sparked widespread attention and discussion in society, increasing public awareness of aerospace technology, enhancing national pride and public scientific literacy, and inspiring more young people to develop an interest in science and a spirit of exploration.
