It’s amazing that the world is still seeing innovation on something as simple as a propeller, the limits of science are so vast!
Curious. Could you 3d print a propeller or does it demand some sort of higher quality manufacturing process? For a DIY drone project slapping some toroidal propellers just to test it out seems doable.
It’s been done a lot, but its kinda pointless as any noise improvements from the shape are obliterated by the bad surface finish.
I saw someone 3D print a toroidal prop on YouTube. They tested it and it was 10 times louder than the normal but high quality manufactured propellers. So it would have to be made with a much more precise 3D printing process I think. Link for a laugh 😆
Yes, they still work if they are 3d printed and you can even find files online for them such as this
I remember reading about these a little while ago. Supposedly toroidal propellers aren’t that good for high RPM and high speeds, but they’re really good for things like submarines and they also create no bubbles/sound. Another big benefit is they don’t harm wildlife such as manatees because they don’t have blades.
