In a significant leap for China’s private aerospace sector, the commercial rocket firm Dahang Yueqian has announced the successful completion of core developmental tests for its 'Qingyu-11' engine. This 150-ton class liquid oxygen-methane engine is designed to power the next generation of China’s reusable rockets, positioning the company as a formidable player in a field currently dominated by state-owned giants and high-profile Western competitors like SpaceX.
The development team recently concluded a series of critical milestones, including torch ignition trials, component-level cryogenic tests, and liquid flow simulations. These successful phases have cleared the technical path for the upcoming 'semi-system' test run. According to the company’s internal roadmap, a full-scale, whole-engine system test is slated for the second half of this year, representing the final hurdle before integration into a launch vehicle.
The choice of liquid oxygen and methane as propellants is particularly noteworthy, reflecting a global shift toward more efficient and sustainable spaceflight. Methane is not only cleaner-burning than traditional kerosene but also significantly easier to manage for reusable systems, as it leaves less residue in the engine components. Dahang Yueqian’s focus on a 150-ton thrust class indicates an ambition to support heavy-lift missions, which are essential for China’s plans to deploy massive satellite constellations.
As Beijing continues to open its space industry to private capital, the progress of firms like Dahang Yueqian serves as a barometer for the country’s technological maturity. While state-run organizations focus on lunar exploration and space station maintenance, the private sector is increasingly tasked with driving down the costs of low-Earth orbit access. The successful deployment of the Qingyu-11 could provide the heavy-duty, reusable power required to make China’s commercial satellite industry globally competitive.
