This is a 12 paddle wheel designed for low head, low velocity flow. Very light and efficiently designed. Parts are modular and snap together.


Needed - 1 inner wheel, 12 paddles.

STL and solid works parts are included. If you have any suggestions for improvements, I would be happy to make them.

The paddles snap into position.

Model has been printed and tested successfully. Pictures to come.

Thanks for posting this. Just wondering, did I do something wrong with the scaling? I had to scale it up 20x. That made it about 100m diameter. Then the clearances were too small, I have modified them, now they fit together. Just wondering, what did you use as a generator? Just a regular DC motor?

I am always pondering water wheels and really like the pelton wheel configuration. Your design is awesome! The snap together design simplifies the building as well as the printing.What software did you use to design this? It looks great.  

I'm glad you like it! The paddles are designed to snap together to allow changes to be made without adding a lot of expense. I used Solidworks to design the model.

I edited the comment after I seen the file types (oops). Are you planing to build one?

Already built and tested! Unfortunately they are at my University waiting for our competition. I'll put one up soon however,

Have you tested it under load? I find it really hard to imagine the snap-on design can bear the force exerted upon the spoon when the axle is under the resistance of a loaded generator.

Well it depends on what material you print with. I used a Stratasys 3D printer with their proprietary ABSPlus material. With that material, it was plenty strong, at least for our tests! I've not tested it with regular ABS.

How did the competition go?
