Re: V22 Osprey
IFMU,
I am not privy to the latest info, but flew the ABC back when, and understand the concept well. The counter rotating coaxial design is at home in the hover, and is very efficient, as well as having unlimited yaw control. Dave Jackson can go on from here!
It is optimized for hover, except for the +10% lost payload it suffers from carrying the propulsor and shroud that allow it to go to high speed.
