Hydrogen-oxygen engine

Meanwhile, the high-thrust hydrogen-oxygen engine of China’s Long March-5 Y6 carrier rocket passed its calibration test on Tuesday.

This calibration experiment is a kind of short-range ground test under rated conditions of an engine ready for delivery to the final rocket assembly with the purposes to check and adjust performance parameters.
