CEFOSKEY,
One or two questions (you might know the answers):
How does that collective work? Rearwards for increased thrust?
Does sidestick include yaw control?
Is the terrain display something Sikorsky is actively working on or is it just on the wish list?

Dave,
That prop position is just a compromise required by the drivetrain. Don't forget that tail rotor drivelines will be designed to all sorts of inhouse analysis procedures. Besides prop is only really active in cruise where mass flow is high enough to reduce required thrust. The other way to see it is that any streamline passing through rotor disk and prop disk is effectively just being revectored by prop so that rotor does all the hard work of increasing total pressure (treating aerofoils as a planar pumping machine). I've read up a bit since that stimulating discussion about ground effect pressure under the rotor.
So your intermesher is a sub 200kts machine then? In that case it is not ABC and cannot be compared to X2 (threadjack caution light
). If it was ABC then my point about retreating blade unloading stands, by definition of ABC. In hover, if you fatigue the rotors hard enough, you could achieve any downwash pattern you wanted. Best to keep mechanism simple = durable...
