Mega Engine Technology Achieves Milestone with Oxygen-Rich Staged-Combustion Engine
Mega Engine Technology, a commercial startup based in Xi'an, China, has announced a significant achievement in rocket engine development. The company has successfully accumulated 1,000 seconds of test time on a high-pressure oxygen-rich staged-combustion kerolox engine, named Chi. This engine is notable for its rapid startup, stable operation, and intact hardware post-testing. The engine's performance places it in the category of engines suitable for reusable medium-lift launchers, with a sea-level thrust throttleable between 35 and 75 tons, rising to 87 tons in vacuum. The development of such an engine typically takes a decade, but Mega Engine has achieved this in under two years, suggesting a rapid advancement in their engineering capabilities.
