Difference between Jet engine and Rocket engine

Jet engine vs. Rocket engine

A jet engine is a type of reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. A rocket engine uses stored rocket propellant mass for forming its high-speed propulsive jet.

Air-augmented rocket

Air-augmented rockets (also known as rocket-ejector, ramrocket, ducted rocket, integral rocket/ramjets, or ejector ramjets) use the supersonic exhaust of some kind of rocket engine to further compress air collected by ram effect during flight to use as additional working mass, leading to greater effective thrust for any given amount of fuel than either the rocket or a ramjet alone.

Airbreathing jet engine

An airbreathing jet engine (or ducted jet engine) is a jet engine propelled by a jet of hot exhaust gases formed from heated and expanded air that is drawn into the engine via a compressor, typically a centrifugal or axial type.
