FG-36

The FG-36 (AKA Fengyun 2 AKM) was a Chinese spin stabilized apogee kick motor burning HTPB-based composite propellant. It was developed by China Hexi Chemical and Machinery Corporation (also known as the 6th Academy of CASIC) for use in the Fengyun 2 satellite bus for insertion into GSO orbit.

It has a total nominal mass of 729 kg, of which 650 kg is propellant load and its burn out mass is 79 kg. It has an average thrust of 44 kN with a specific impulse of 289 seconds burning for 43 seconds, with a total impulse of 1.842 MN. While it was designed as an apogee kick motor and as such it flew in spin stabilized mode, it was also adapted to the Long March 1D third stage. It was paired with a RCS in a similar solution to the CTS.
