#1 I am somewhat mystified why no one has ever developed centrifugal fan, "fanwing"-type pods for helicopters, for better efficiency as well as greater lift.

While it may not be optimal for a combat aircraft, it would seem to be just the thing for a cargo aircraft. Centrifugal fans are simple, strong, stable, and have better lift than rotors. And reducing the load on the rotors would make a helicopter much more fuel efficient.

#2 They did try it, back in the 1960's. IIRC, it turned out to be less efficent/ useful/ robust/ idiot-proof than the rotor systems we still use today.

Otherwise, we would be already using centifugal fans today.

#3 I've long been interested in this stuff. If you have any links or pics they would be appreciated. I know a British company that has been doing a lot of R&D with fanwings.
