CZ-2C/FP运载系统变轨发动机(FG-47)

FG 47 Orbit transferring Solid Rocket Motor of CZ 2C/FP Launching System

ＦＧ４７固体发动机是ＣＺ２Ｃ／ＦＰ运载系统轨道转移动力装置，它可以将卫星（如铱星）从椭圆停泊轨道转移到６３０ｋｍ圆形运行轨道。该发动机由中国航天工业总公司河西化工机械公司研制，于１９９７年９月首飞成功，将一个模拟卫星送入轨道。

FG 47 solid rocket motor is the orbit transferring propulsion device for CZ 2C/FP launching system which can transfer the satellite (such as the Iridium Satellite) from the elliptical parking orbit to the 630km circular operating orbit. It was researched and developed by Hexi Chemical Machinary Corp. of CASC and first successfully flighted in Sep 1997 to send a simulated satellite into the orbit.
