COMPOSITE PROPELLANTS |
 |
Composite propellants
are heterogeneous mixtures of fuels and small particulate oxidizers held
together by a rubbery material referred to as the binder. They provide
a stable, high-performance, solid propellant for rocket motors.
Composite propellants are used to provide the propulsive energy for rocket
systems, kick motors for satellites, and for booster motors for launching
cruise missiles and unmanned air vehicles (UAVs).
Composite Propellant ingredients offered by IPI:
ALUMINUM
POWDER
MIL-A-82728 (OS) specification. Aluminum
powder is the most commonly used fuel component of composite propellants.
This has better performance and greater ease of use than other metal powders
that may be used. Aluminum powder is used to increase the specific impulse
of the propellant and to help stabilize combustion.
AMMONIUM PERCHLORATE
The oxidizing component of choice when dealing with Composite Propellants.
IPI supplies Ammonium Perchlorate in accordance with MIL-A-192B,
MIL-A-82667/2 (OS), MIL-A-82667/1 (OS), MIL-A-23946 (WEP), and
MIL-A-23948 (AS) specifications.
CARBOXYL TERMINATED POLYBUTADIENE LINEAR
(CTPB)
MIL-PRF-23942A (AS) specification. The binder
used in composite propellants is normally a synthetic rubber. Carboxyl
Terminated Polybutadiene Linear is one of the best synthetic rubbers for
this application.
HYDROXYL
TERMINATED POLYBUTADIENE (HTPB)
MIL-H-85497 specification. The binder used
in composite propellants is normally a synthetic rubber. Hydroxyl Terminated
Polybutadiene (HTPB), much like Carboxyl Terminated Polybutadiene Linear
(CTPB), is one of the best synthetic rubbers for this application.
MAPO
(TRIS-1-(2-METHYL) AZIRIDINYL) PHOSPHINE OXIDE)
DOD-T-82666A specification. MAPO is a curing
agent for CTPB prepolymers and a bonding agent for HTPB prepolymers.
CATOCENE
(2,2-BIS-ETHYLFERROCENYL PROPANE)
Catocene is an excellent iron-based burn rate catalyst used in composite
propellant formulations. It can be used to formulate propellants to yield
a burn rate of 1 inch per second or more.
