Picture of Small Scale Wind Turbine
This wind turbine was designed by 4 Glasgow School of Art students as part of our Product Design Engineering course. The aim of this project was to create a wind turbine that would yield the highest power output when in a wind tunnel. This particular design proved to be the best ever and produced a little over 20 volts when loaded with a sizable resistor.

Step 1: Component Parts

Picture of Component Parts
All component parts. Some size-able machinery is required for a project such as this, for example:
Welder, engineering lathe, turret mill, accurate metal cutting saw, drill press, rapid prototyper and more.


Column, 5 aerofoil blades , main shaft, 2 shaft bearings (C3 (loose running), not sealed so grease can be replaced by light oil), 2 shaft locking collars, nose cone, 24 volt rated motor, 2 pulley wheels with a 3.75 : 1 ratio, drive belt, motor mount and various nuts and bolts.

Step 2:

Screw blades onto nose cone and secure with locking nuts.

Step 6:

where did you attach the wires to produce eletricity

Are you able to post the dimensions of the blades or possibly even the cad file? I have access to a 3D printer and I would really enjoy making one of these!

Did you cut the aerofoil blades yourself or did you buy them pre-cut? If you did it yourself, how did you go about doing it - I'm thinking of building a wind tunnel and will probably make my own propeller?

Hi, the aerofoil blades were drawn up on CAD (Solidworks) and from this we made 1 using a 3D printer. From this prototype blade we made a silicon mould and cast 5 blades with a metal supporting rod running through the middle of each.

Good luck with your creation!!
Ok, thanks a lot for the detailed answer and the quick response!
