Air turbine spinning at around 13,000 rpm

An impulse air turbine I made as part of my college course, running without its upper casing in place. We had a strobometer on it, and it was measuring about a peak of 230 revs per second, which is around 13000rpm. The metal strip along the top is there to stop the impeller shooting out because of the air pressure on it.

whats the practical use of this ?

[0saintsfan0]

@salmasalamahmed in this form, it doesn't really have a practical application, it was merely a design and make project for college, but these sort of air motors in general are used in dental drills, for example, as they can generate very high speeds (up to 800,000rpm in proper dental drills.)

Dunno, but it supplies the whole hydraulics/pneumatics lab, I think.

How much vibration did you feel when it was at maximum speed? And what was the radius of this turbine? Also is it an radial turbine you're using?

@salmasalamahmed 800k rpm, sounds painful

@superwing123 Google it!

[scottaspect20]

is it a tesla turbine?

[qwasd0r]

@superwing123 Works like a water turbine, only with highly compressed air... I guess.

[omzi79]

That was invented by Nikola Tesla, am I right?

What is exactly an air turbine? Please answer, I want to build my own one this summer.
