Jielong-1
The Jielong-1 ( Chinese 捷 龙 一号 , English Smart Dragon 1 , "Kluger Drache 1"), SD-1 for short , is a Chinese launcher . It is used to launch small satellites and completed its maiden flight on August 17, 2019. The rocket is being built by Chinarocket (中国 长征 火箭 有限公司, Pinyin Zhōngguó Chángzhēng Huǒjiàn Yǒuxiàn Gōngsī ), a subsidiary of the China Academy of Launch Vehicle Technology founded on October 19, 2016 .
Structure and technical data
The Jielong-1 is a four-stage rocket with solid propellant . It is 19.5 meters high, has a diameter of 1.2 meters and has a takeoff weight of around 23 tons. A special feature is the reverse arrangement of the fourth stage, the engine of which points in the direction of flight during take-off. The payload is accordingly between the third and fourth stage. After the third stage has been disconnected and before the last engine ignition, the fourth stage is rotated 180 degrees.
All Jielong-1 launches are carried out by a mobile device , which is particularly common with military missiles. This enables short-term use; the start preparations should only take one day.
The manufacturer specifies a payload capacity of 200 kg for sun-synchronous orbits at an altitude of 500 km. At an altitude of 700 km, a payload of up to 150 kg should be possible.
