Recently, three flight engines from Jiuzhou Yunjian Longyun have completed calibration tests and are about to be delivered to customers for rocket installation. This is also the second rocket customer delivered by Longyun Engine.

The Longyun engine delivered this time will be used for 10km and 100km level flight recovery missions, and the engine technology status and multi aircraft parallel connection status are consistent with the future launch vehicle status.

Jiuzhou Yunjian Longyun engine has officially entered the engineering application stage, which will accelerate the engineering landing of China's liquid oxygen methane reusable carrier rocket technology.
