On December 10, 2023, a remarkable feat in the realm of aerospace was achieved. Beijing-based Interstellar Glory Space Technology Co., Ltd. successfully completed its second flight test of the SQX-2Y reusable liquid oxygen-methane rocket. This event marks a pivotal milestone in China’s aerospace history, showcasing the nation’s burgeoning expertise in reusable rocket technology.
The SQX-2Y rocket, having first completed its maiden vertical takeoff and landing flight test on November 2, 2023, represents a significant leap in the field of aerospace. This recent flight test saw the rocket reach a height of 343.12 meters, lasting for 63.15 seconds, and achieving a lateral displacement of 50 meters. Notably, the precision of its landing was remarkable, with a landing accuracy of approximately 0.295 meters and a descent speed of 1.1 m/s.
A critical aspect of this mission was the rapid reuse capability of the JD-1 liquid oxygen-methane engine used in the rocket. This technology not only underscores the potential of liquid oxygen-methane as a cost-effective and maintenance-friendly propellant but also highlights the advancements made in vertical recovery, aerodynamic, and thermal interference management.
