Need suggestions on transfering compressed air to rotating object

SUMMARY

This discussion focuses on methods for transferring compressed air to a rotating object, such as a tire or barrel. Key suggestions include using a tight seal at the axis, though this may increase friction. An alternative proposed is incorporating an electric air compressor within the rotating apparatus, requiring only an electrical connection. The feasibility of utilizing a Tesla turbine for air compression was also considered, but it was concluded that the efficiency would be low at typical wheel RPMs of around 100, as the turbine operates best at thousands of RPMs.

PREREQUISITES
  • Understanding of pneumatic systems and compressed air mechanics
  • Knowledge of electric air compressors and their applications
  • Familiarity with Tesla turbine design and operational principles
  • Basic concepts of rotational dynamics and friction in mechanical systems
NEXT STEPS
  • Research the design and efficiency of electric air compressors for rotating systems
  • Explore advanced designs of Tesla turbines for optimal RPM performance
  • Investigate methods to minimize friction in rotating seals
  • Learn about the integration of pneumatic systems with electric motors
USEFUL FOR

Engineers, mechanical designers, and anyone involved in the development of rotating machinery or pneumatic systems will benefit from this discussion.

If you had a rotating object like a tire or barrel that you wanted to distribute compressed air to while it's rotating, what would some ways to do it? One way I'm thinking is just a tight seal at the axis, but then there would be a lot of friction. Any other ideas??

You could incorporate an electric air compressor in the rotating part of the apparatus. That way you'd only need an electrical connection to the rotating part instead of a compressed air connection.

How fast is the rotation? If it is really fast, you could use this rotation for compression (would still need some active parts I guess, but not a full-scale compressor).
 
I was thinking about a tesla turbine to turn a wheel. Except that I was trying to think of how to make the discs double as spokes for the wheel. It could be done, but I just realized it would be very inefficient because the rpm of the wheel would only be about 100. And an air compressed tesla turbine would run moat efficiently at many thousands of rpms. So nevermind. Thanks for the suggestions.
