Liquid propulsion systems

Liquid propulsion systems use liquid fuels and oxidizers stored in tanks and pumped into a combustion chamber. Inside, these substances ignite and produce high-pressure gases that rapidly expand and are expelled through a nozzle, generating thrust to propel a spacecraft. They offer precise control over engine performance, enabling adjustments during flight. Common in rockets, they provide high efficiency and the ability to restart engines in space, making them ideal for missions requiring agility and sustained power. Examples include liquid hydrogen and liquid oxygen engines used in many space launch vehicles.
