Liquid Fuel Engine

A liquid fuel engine is a type of rocket engine that burns liquid propellants—usually a combustible liquid fuel and an oxidizer—to produce thrust. These engines are precisely engineered to mix and burn the liquids efficiently, creating a high-velocity jet of hot gases that propel the spacecraft forward. Because the fuel and oxidizer are stored separately, they can be controlled and cycled on or off, allowing for precise maneuvering and restart capabilities. Liquid engines are commonly used in space missions due to their reliability, efficiency, and ability to be throttled for different speeds and stages of flight.
