The main engine of Pallas No. 1 has been tested for 20,088 seconds in total and can be reused more than 25 times.

Recently, the Cangqiong-50 reusable liquid oxygen kerosene engine independently developed by Galaxy Power completed its 163rd normalized hot test. The cumulative test time of the entire engine was fixed at 20,088 seconds, and the longest test record for a single engine reached 2,757 seconds.After 57 complete machine ignition tests, the stable performance of this engine has been fully verified, laying a solid foundation for the first flight and first-stage recovery test of the medium-to-large recyclable rocket Pallas 1.

The Qiongqiong-50 adopts a pin-bolt injector design and natively supports multiple ignitions and depth thrust adjustment.The official set reuse life is no less than 25 times, and more than 40 engines have been assembled and delivered.

It can smoothly adjust the thrust within a wide range of 32% to 105%, with a thrust control accuracy of only 0.5%. It has also completed the exclusive recovery working condition test of ignition, taxiing, and secondary ignition, accurately matching the control requirements of the rocket's vertical soft landing.

The 3D printing thrust chamber tailor-welding process is extensively used in the manufacturing process. Compared with traditional solutions, the production cycle is shortened by 30% and the manufacturing cost is reduced by 15%. At the same time, the inspection and maintenance process after commissioning is optimized, and quick re-inspection is possible without disassembly, which greatly improves the efficiency of batch delivery.

As the carrying platform for this engine, the Pallas-1 reusable liquid rocket will make its first flight in the near future. In the future, one-stage recovery tests will be gradually carried out, and eventually normalized commercial reuse launches will be realized.

Galaxy Power is a domestic private rocket company capable of stable and continuous launches. It has a complete launch product line of the solid Ceres series and the liquid Pallas series, and has set many industry firsts in the fields of multiple orbits, sea launches, and high-density mass production.
