- Liquid rocket fuel.
- Oxidizer.
- Pumps carry the fuel and oxidizer.
- The combustion chamber mixes and burns the two liquids.
- Combustion product gasses enter the nozzle through a throat.
- Exhaust exits the rocket.
A liquid-propellant rocket or liquid rocket utilizes a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (Isp). This allows the volume of the propellant tanks to be relatively low.
