In a significant advancement for China’s commercial space sector, Beijing-based Galactic Energy has successfully completed a comprehensive system test for the engine powering its reusable PALLAS-2 rocket. The breakthrough test, conducted recently, marks a pivotal step toward the development of China’s indigenous reusable launch vehicle technology.
The CQ-90 liquid oxygen-kerosene engine, an upgraded variant of the company’s earlier CQ-50 model, demonstrated exceptional performance during the rigorous testing phase. According to official reports, the engine achieved smooth ignition, maintained stable operation throughout the test duration with highly visible flame characteristics, and executed a flawless shutdown sequence.
Performance data confirmed all parameters met or exceeded design specifications, with combustion efficiency reaching an impressive 96 percent threshold. The CQ-90 engine features advanced capabilities including bidirectional swing functionality of up to 6 degrees, multiple ignition capacity, and wide-range thrust variability – essential characteristics for reusable rocket operations.
The PALLAS-2 rocket, measuring 4.5 meters in diameter, will be available in two configurations. The baseline version will possess a lift-off mass of 757 tonnes, generating 910 tonnes of thrust with capacity to deliver 20 tonnes to low Earth orbit. An enhanced strap-on booster configuration will substantially increase capabilities to 1,950 tonnes lift-off mass, 2,730 tonnes of thrust, and 58 tonnes to low Earth orbit.
This technological achievement positions Galactic Energy as a competitive player in the global commercial space market and demonstrates China’s growing capabilities in reusable launch vehicle development, potentially reducing space access costs and increasing launch frequency capabilities.
