Suction turbine

This design is a vacuum turbine, that is able to generate enough force as to attach it to the ceil. It works with a small motor (the motor of the tail rotor of small RC electric helicopter).
It is a preliminar study, so, the design is parametriced in order to allow the modification of the motor, the stator or the turbine.

I've been grateful surprised by the first results. The idea is to use the rotation speed instead of torque using not only the centrifugal force also the Ventury effect.
