Re: [TCML] RSG Disk Loading?



 

 Greg,

The rotor definitely causes a lot of air drag.  I think most of the drag is due to
the electrodes.  I'm not sure how much drag the rotor surface causes.

Regards,
John

RSG Gurus,

What is the source of "disk loading"?  How can an RSG rotor, which appears to be 
no more than a flywheel, load down a motor?  Mass alone isn't a load once the 
inertia of the disk is overcome and the motor spins up to its rated RPM.  All 
that leaves is air drag.  Do the flying electrodes account for significant air 
drag?  Does the surface of the rotor itself move enough air to load the motor?  
My education in classical physics ended with high school.  I'm mostly 
self-taught in electric motors.  What am I missing?

Cheers,

Greg
