Lingyun engine
Jiuzhou Yunjian's first engine for the commercial launch market, a methane and liquid oxygen engine that can restart, throttle deeply and be reused.
Why it matters
Lingyun gave the company a sellable product before its high-thrust Longyun engine, and engines that restart and throttle deeply are what landing tests and reusable stages need.
How the technology works
Like Longyun, it burns liquid methane and liquid oxygen and is designed for multiple restarts and deep throttling to support reuse. The company does not publish its thrust on its website.
