The China Aerospace Science and Technology Corp (CASC) has successfully tested a 130-ton reusable liquid oxygen kerosene engine, marking a significant milestone for the country’s space program. This engine has broken the previous record for liquid rocket main engine testing in China. It is intended to power CASC’s reusable rockets, such as the Long March 10.
The latest tests, which included two ground-based ignition tests on April 13, represent a major advancement in China’s aspirations to take the lead in space exploration. The engine has completed over 3,900 seconds of testing, including 15 iterations and 30 ignition starts, proving its robust expandability and dependability.
The key to the engine’s efficiency lies in its multiple ignition capability and large-range thrust adjustment, essential for its role as a reusable engine. The research team behind the engine’s development has also focused on simplifying maintenance and assessment technologies to ensure its longevity through multiple reuses.
China’s objective to outpace the US in space exploration includes advancements in the space industry. With plans to conduct test flights for two state-owned reusable rockets in 2025 and 2026, China is quickly developing its capabilities, while NASA has come under fire for depending too much on antiquated technology, such as the Space Launch System (SLS).
Furthermore, a number of private Chinese space companies are creating their own reusable rockets, some of which hope to launch this year. For instance, Galactic Energy is developing the reusable Pallas-1 rocket and intends to conduct a test flight that may result in recovery.
With these developments, China is positioning itself as a major player in the space industry, with a growing fleet of reusable rockets that could revolutionize space travel in the coming years.
