The pictures only show the tail section -- that's the rear rotor in the photos..
Ah, that makes a lot more sense than how I was picturing it. Thanks!
"What the hell's this? A helicopter for ants?"
Yeah, part of the back, maybe ECM detail, looks like it should be the front, and it crossed my mind it might be a drone.
But yeah, just the back part.
It has to be at least... three times that size!
The hub looks to serve the same purpose as the ducting around the tail rotor in the canceled Comanche project. It serves to reduce interaction between the main rotor and the tail rotor, thereby reducing the amount of noise the helicopter makes.
