How does a jet engine work? A 3D preview

Explore core and bypass airflow in a 3D turbofan cutaway, then continue the full lesson through AAP or Cadet Preparation.

After the fan, air divides into two streams. Core air passes through the compressor, combustor and turbines. Bypass air travels around the core. Both streams contribute to thrust.

Rotate and zoom the model in this short preview. Try Overview and Intake & fan; the full course adds compression, combustion, turbine power, exhaust and thrust, and a knowledge check.
