The FG-15 (AKA DFH-2 AKM and SpaB-170) was a Chinese spin stabilized apogee kick motor burning HTPB.〔 It was developed by China Hexi Chemical and Machinery Corporation (also known as the 6th Academy of CASIC) for use in the Dong Fang Hong 2 satellite bus for insertion into GSO orbit.〔 It has a total nominal mass of , of which is propellant load and its burn out mass is . It has an average thrust of with a specific impulse of 289 seconds burning for 35 seconds, with a total impulse of . This motor introduced a series of innovations for the Chinese solid motor industry: first use of glass fibre wound cases, carbon/carbon nozzle throat insert material, contoured divergent nozzle, and non-destructive test of the motor grain. The initial version had the manufacturing code FG-15 was associated to the DFH-2 bus and flew twice. The FG-15B was used by the DFH-2A bus and flew five times. ==See also== * China Hexi Chemical and Machinery Corporation * Dong Fang Hong 2 * Long March 3 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「FG-15」の詳細全文を読む スポンサード リンク
