Propellant
*** Shopping-Tip: Propellant
A '''propellant''' is a material that is used to move an object by applying a motive force. This may or may not involve a chemical reaction. It may be a
gas,
liquid,
Plasma (physics) plasma, or, before the chemical reaction, a solid. Common chemical propellants consist of a fuel, like
gasoline,
jet fuel and
rocket fuel, and an
oxidizer.
Aerosol sprays
In
aerosol spray cans, the propellant is simply a pressurized vapour in equilibrium with its liquid. As some gas escapes to expel the payload, more liquid evaporates, maintaining an even pressure. (See
aerosol spray#Propellant aerosol spray propellant for more information.)
Solid propellant rockets and projectiles
In
ballistics and
pyrotechnics, a '''propellant''' is a material which burns very rapidly but controllably, to produce
thrust by
gas pressure and thus
accelerate a
projectile or
rocket. In this sense, common or well known '''propellants''' include, for
firearms,
artillery and
solid rocket solid propellant rockets:
*
Gunpowders, such as
**
Black powder
**
Nitrocellulose
**
Cordite
**
Smokeless powder
*
Composite propellants made from a solid
oxidizer such as
ammonium perchlorate or
ammonium nitrate, a rubber such as
HTPB or
PBAN, and usually a powdered
metal fuel such as
aluminum.
*Some
amateur rocketry amateur propelants use
potassium nitrate, combined with
sugar,
epoxy, or other fuels / binder compounds.
*
Potassium perchlorate has been used as an oxidizer, paired with
asphalt,
epoxy, and other binders.
Liquid propellant rockets
Common '''propellants''' for
bipropellant rocket liquid propellant rockets include:
*
RFNA and
kerosene or
RP-1
*
RFNA and
UDMH
*
Dinitrogen tetroxide and
UDMH,
MMH and/or
Hydrazine
*
Liquid oxygen and
kerosene or
RP-1
*
Liquid oxygen and liquid
hydrogen
*
Hydrogen Peroxide and
alcohol or
RP-1
