propellant
Thrust-producing substance
A propellant is a substance that provides thrust or drives something forward.
In rocketry, propellants are fuels and oxidizers that combust to produce gases expelled at high speed: solid rocket propellant, liquid propellant engines.
In aerosol cans, the propellant is a compressed gas that forces contents out when the valve opens.
Bullets use explosive propellants to leave the barrel.
Also spelled propellent.
