Chinese Commercial Launcher Tests Deep‑Throttle, Reusable LOX‑Kerosene Engine Built with 3D‑Printed Stainless Steel

Zhongke Yuhang has completed acceptance tests of its Liqing‑1 30‑ton LOX‑kerosene engine, demonstrating deep throttle (100%–50%) and 1% thrust precision, using a needle‑and‑pin injector and stainless‑steel 3D‑printed components. The company plans to use three Liqing‑1 engines on its LiHong‑2 reusable vehicle and is preparing larger Liqing‑2 tests, marking a material advance for China’s commercial reusable‑rocket ambitions.
