From Wikipedia, the free encyclopedia
The
FG-15
(AKA
DFH-2 AKM
and
SpaB-170
) was a
Chinese
spin stabilized
apogee kick motor
burning
HTPB
-based
composite propellant
.
[3]
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.
[4]
It has a total nominal mass of 580 kg (1,280 lb), of which 505 kg (1,113 lb) is propellant load and its burn out mass is 75 kg (165 lb). It has an average thrust of 40.9 kN (9,200 lbf) with a
specific impulse
of 289 seconds burning for 35 seconds, with a total impulse of 1.432 MN (322,000 lb
f
). 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.
