Rocket Nozzle
A shaped passage that turns high-pressure gas into directed exhaust.
Why it matters
Nozzle design directly affects how effectively an engine uses its propellant.
Technology / launch propulsion
Overview
Nozzles connect combustion conditions to useful thrust. Their geometry must suit the engine and operating environment. A nozzle optimised for vacuum is not necessarily ideal at sea level.

How it works
Flow accelerates through a narrow throat and expands in the diverging section. The resulting exhaust velocity and pressure difference contribute to the force on the rocket.
