China’s “Lijian-1” carrier rocket is a new-type solid-propellant launch vehicle used to send six scientific experiment satellites into orbit July 27th.
The rocket has played a role in enriching China’s solid-propellant carrier rocket family with various technological innovations.
The Lijian-1 launch vehicle was launched for the first time from the Jiuquan Satellite Launch Center, Gansu Province, northwest China. Also known as ZK-1A, this four-stage solid-propellant launch vehicle was jointly developed by the Institute of Mechanics of the Chinese Academy of Sciences and CAS Space (Beijing Zhongke Aerospace Exploration Technology Co., Ltd.).
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.
Only after passing the calibration test can an engine be officially installed on the rocket.
