Based on that patent application, it appears that the original X3,
with engine mounted props facing forward, adjacent to the ingress/exit of the cabin, has been changed in the patent sketch to be pusher props with props well behind ingress/egress to the cabin.
The video chooses "next fastest" as Chinook ... uh, CH-53E is pretty fast its own self with an advertised 170 know/196 mph speed ... and I think it has flown faster than that.
I guess they ignored Sikorsky's most recent 200 kts plus design (X-2) that is moving head into the S-97?
Anyway, looking forward to seeing that one fly to see what it adds to the state of the art.
