Liquid-Propellant Engine
An engine that feeds liquid reactants into a combustion chamber.
Why it matters
Separate propellant feeds offer ways to regulate performance throughout a mission.
Technology / launch propulsion
Overview
Liquid systems separate storage from combustion. Pumps or pressurised tanks supply the reactants. Restart and throttle capabilities are design-specific, not automatic features of every liquid engine.

How it works
Injectors mix fuel and oxidiser so they burn in a controlled chamber. Cooling protects the walls while hot gas expands through the nozzle.
