A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. Liquids are desirable propellants because they have reasonably high density and their combustion products h
Bipropellant liquid rockets are simple in concept but due to high temperatures and high speed moving parts, very complex in practice.
