Science Art: Schéma de montage d’un turbopropulseur by Nerijp


This is a turbine – a “turbopropulseur” – used as an example of a “réducteur” – a reducing gear. The one end spins a lot more than the other end thanks to all the gears. Means a motor can make a propeller go around really fast… as long as it’s strong enough.

That’s the secret of the turboprop.
