220-ton liquid oxygen methane rocket engine "Blue Flame" completed the full-system test.

Recently, the 220-ton liquid oxygen methane full-flow staged combustion cycle engine "Blue Flame" developed by Blue Arrow Aerospace has completed long-term testing of the entire system, marking a significant breakthrough in China's field of high-thrust, high-performance liquid rocket engines. The "Blue Flame" engine adopts the internationally advanced full-flow staged combustion cycle configuration, and uses the overall technical solution of high integration design and high chamber pressure design. It is an important power infrastructure and core supporting capability for the development of China's next generation of large and heavy launch vehicles, laying the foundation for the construction of an efficient and reusable heavy launch power system.
