Galactic Energy recently carried out a full-system hot-fire test of the main engine (CQ-90) for its Pallas-II large reusable launch vehicle, achieving complete success. During the test, the engine started smoothly, operated stably in the main stage with bright flame, and shut down normally. All components, including the turbopump, gas generator, valves, and assembly pipelines, worked in coordinated harmony, fully validating the technological maturity and reliability from core components to overall integration. Test data indicates that all performance parameters of the engine meet design specifications, with combustion efficiency exceeding 96%, reaching advanced levels in China.
