Splinedrive. I was basing my statement on the patents filed by Karem. So my statement may be out of date, having been based on earlier configuration.
I have not yet seen in a published application a configuration with generators and cooling in the spinner. I’ll do a search.....

This is the latest I can find, and it’s back from 2009. Can you direct me to any later information? I have looked at power generation for IBC in the rotor under research I was doing. But the differential speed between the mast and the rotor required a heavy gearbox to get adequate speed for the generator. Would be interesting to see how he got around this issue.
