China has achieved a significant milestone in its space exploration efforts by successfully completing the full-engine test of a powerful 140-tonne liquid oxygen-methane engine. The engine, developed by the China Aerospace Science and Technology Corporation’s Academy of Aerospace Propulsion Technology, is set to play a crucial role in the nation’s future reusable carrier rockets.
The new engine boasts the largest thrust among China’s current open-cycle liquid oxygen-methane engines. Designed to power reusable rockets, it will be instrumental in advancing space-Earth transportation systems, reusable launch vehicles, and the development of heavy-lift rockets.
“This successful test marks a breakthrough in the production of China’s hundred-tonne-class liquid oxygen-methane engines,” the academy stated. Remarkably, the development process was completed in just seven months, highlighting the team’s efficiency and dedication.
In December 2022, the academy tested a 90-tonne reusable liquid oxygen-kerosene engine for commercial spacecraft, marking a milestone achievement since it began focusing on the commercial space sector. The commercial space industry was listed in the country’s 2023 government work report as a “new engine of economic growth.”
Looking ahead, the academy announced plans to dedicate more efforts to developing even heavier engines, specifically targeting reusable 200-tonne liquid oxygen-methane engines. These advancements are expected to significantly boost China’s capabilities in space exploration and technology.
