The TH-11 is an oxidizer-rich staged combustion cycle rocket engine burning LOX and kerosene developed by Space Pioneer. The TH-11 engine features a reusable design, staged combustion cycle, wide usage of 3D printed components, and short development time, making it a notable achievement within the Chinese commercial space industry.

History

Space Pioneer proposed the TH-11 engine for its Tianlong-2 launch vehicle. Full-system hot-fire tests were completed in June 2021. The Tianlong-2 rocket successfully completed its maiden flight on April 2, 2023, achieving the targeted orbit. Powered by a single Tianhuo-11 engine in its second stage, this launch marked the engine's operational debut.
