Definition
A rocket engine is a type of jet engine that uses stored propellant to create thrust. Unlike air-breathing jet engines, rocket engines carry their own oxidizer, allowing them to operate in the vacuum of space. π₯ The engine works by igniting a propellant (fuel and oxidizer) and expelling the hot gas through a nozzle. This generates tremendous force, pushing the rocket forward. They are incredibly powerful and used for space travel, missiles, and some high-speed experimental aircraft.
