NickLappos-
The S-97 prototype rolled out last Oct. sure is a pretty aircraft, and I hope it performs as good as it looks.
Are there any technical developments being used on the S-97 (beyond those obvious from published photos) that you can publicly discuss? There isn't much on the internet and I didn't find anything in the AHS index. I'd love to learn more about the S-97's unique rotor hub arrangement and drivetrain. Has Sikorsky published any technical papers on the rotor hub or drivetrain that are available to the general public?
