[CQ-50 Engine Completes High-Precision, Large-Gradient Depth Variable Thrust Test]
On the week of 19 November 2025, Recently, Galactic Energy Aerospace successfully completed a variable thrust test of the CQ-50 (CQ-50) liquid oxygen/kerosene engine, the main engine of the Zhishenxing-1 launch vehicle. The CQ-50 series engines utilize Galactic Energy Aerospace’s self-developed needle-bolt thrust chamber design, which boasts high combustion efficiency, strong adaptability, low production cost, and easy iterative optimization. It also exhibits advantages such as stable combustion and strong adjustment capabilities under various operating conditions. This test covered variable thrust experiments under three typical operating conditions, focusing on verifying five core technical indicators of variable thrust, providing crucial power support for the breakthrough in reusable technology of the Zhishenxing series.
