Vane Air Engine

A simple vane air engine that runs on compressed air. Air enters tangentially 
through the inlet pipe and pushes against curved vanes attached to a central rotor 
shaft, causing it to spin. Designed in Onshape and printed in PLA (PETG advised for 
better heat/wear resistance).

Assembly: Drop the rotor into the housing, then glue on the lid, followed by the 
intake valve. No additional hardware required.

Tip: A bit of sanding on the contact surfaces helps smooth out print defects and 
can improve RPM. A drop of WD-40 or similar lubricant also reduces friction for 
smoother spinning.
