Jet Engines

Jet engines make airplanes move by pulling in air, squeezing it, mixing it with fuel, and blasting hot gas backward.

How It Works

Jet engines create thrust, the forward push that moves an aircraft. Most large passenger airplanes use turbofan jet engines.

Why It Matters

A jet engine has spinning blades, a compressor, a combustion chamber, and a turbine. Jet engines helped airplanes fly much faster than propeller planes.
