(Xi’an Bright Laser Technologies Co.: Xi’an, Shaanxi, China) -- Space Circling Aerospace Technology Co. recently completed a successful 50-second engine test of its independently developed, 85 ton-class rocket engine, QL-1 (QiaoLong-1). The engine demonstrated smooth ignition, rapid shutdown, and stable, high-efficiency operation throughout the test, marking another significant milestone in the development of China’s commercial space propulsion capabilities.

This achievement was made possible not only by Space Circling’s dedicated engineering efforts, but by Xi'an Bright Laser Technologies’ (BLT) critical support in metal 3D-printing technology.
