CQ-90 Reusable LOX/Kerosene Engine
The CQ-90 engine is an improved and optimized iteration developed by Galactic Energy based on the CQ-50 engine. By adopting advanced technologies such as post-pump two-axis gimbal, pyrotechnic-free design, copper alloy 3D printing, and high-precision flow regulation, the engine's performance and thrust have been significantly enhanced. It is mainly used to support the Pallas-2 series of launch vehicles.

CQ-50 Reusable LOX/Kerosene Engine
The CQ-50 engine is the first open-cycle, deep throttling, reusable LOX/kerosene engine independently developed by Galactic Energy, mainly matched with the Pallas-1 series of launch vehicles. The engine adopts innovative designs such as a new pin-type injector, coaxial split dual high-speed turbopump, and spherical multi-reflow vortex gas generator, as well as advanced manufacturing technologies including 3D printing and diffusion bonding. It enables multiple restarts, reusability, and wide-range continuous deep throttling, featuring low cost, long service life, high thrust-to-weight ratio, and high reliability.
