“That is where I disagree.”
I was referring to the idea of altering the angle of the rotor between traditional prop airplane to helicopter. Having a hover-capable vehicle that can cruise over 350 KT is clearly a big win.
Your points are interesting, I’d like to see them evaluated by a qualified aero engineer. One thing I’d note right off the bat is having two counter-rotating props eliminates the torque issue. With a single rotor design, you need a way to counter torque in hover mode.
Plenty of work went into the Osprey design, I’m pretty sure they covered the obvious issues.
Counter rotating props on co-axle shafts negates torque.
Or counter rotating rotors on meshed, twin shafts as the USAF rescue helo from the 60s with no tail rotor.
You are correct in assuming that the rotor system would either be coaxial or a torqueless type of system of which I am not at liberty to speak.
