Good work, the downside to making the air / fluid flow through one exit port is it creates thrust. Pretty design though. Reminds me a little of Tesla’s original 9.75” machine.
Amazing! Do you have the files available onlsine perchance? I have poor cad skills and i worry I will not be able to emulate this success if left to my own devices.
I’ve got some Tesla Turbine models that do over 100,000rpm. Over 50,000rpm just blowing into it with your mouth. It’s called the Tesla Cube. Link to my open source research library can be found in the community section.
How thick should be the inner planes so we know they won't go \|/ and grind against the inner surface? In other words, how do I calculate the incoming pressure limitations?
It depends of the materials you will use and pressure that will work, outer plates should be tapered, so they are very thin on the edges, and thicker in the middle. They don't need to be very thick.
Tesla himself used 1/32” discs on his 6” and 9.75” rotor prototypes. So 0.8mm or 1mm will be fine. I’ve used 0.25mm carbon fibre discs (28mm rotor), 0.8mm 316 SS discs (5” rotor), 0.8mm 420 SS discs (5” rotor) and 4mm 5053 aluminium discs (800mm rotor) and also 3mm 7075 aluminium. I’ve 3D printed rotors in PLA and Nylon / Carbon Fibre. Tesla himself said we don’t need materials higher than 50,000psi tensile strength. The myth being perpetuated about Tesla didn’t have the materials required to make this work is complete BS. Tesla was using German Silver or hardened and tempered steel.
I’ve personally tested many prototypes using up to 750psi. That’s too extreme for 3D printed machines but a normal compressors full pressure of 10 bar will be fine for basic testing.
Nikola Tesla had used in some patents at end of discs a ticker one tapered to support inner discs and each disc would have a ding on one side that would push next disc so there was a point of contact. Also he made dics tapered ticked at center and tinner at edge whivh reduced stress on discs..
Exhaust can be closer to the centre, that is not a problem for 3D printing. But I designed this turbine as it would work on steam. So in order to reuse the steam and condensate it and to reheat it you need to have a closed system. With bearing needed in the center of rotation, you need to go around it to have that channel for closed circulation steam system.

Sorry, how i can do for download the stl file or f3d file? Thanks from Italy 1qq

I don't have that option right now, but I will have it very soon. I will post links under the video.

Your wooden body is just unrealistically cool! Release videos often! :D
Thank you, I will release more soon!
Cool project. Should the exhaust not be closer to the centre, or is that impractical for 3d printing?
Exhaust can be closer to the centre, that is not a problem for 3D printing. But I designed this turbine as it would work on steam. So in order to reuse the steam and condensate it and to reheat it you need to have a closed system. With bearing needed in the center of rotation, you need to go around it to have that channel for closed circulation steam system.
Also, what was the diameter of the nozzle you used?
Nozzle is 5mm diameter, I am making changes now and I will make new improved version. Thanks!
Hi, what was the pressure of the compressed air that you used?
I've used 8 bar compressed air
