Does V-22 Go Twices as Far, carry Twice as Much?

George,

I have seen that arrangement before, it seems to have the ability to blend
the properties of a helicopter and a wing, but there are enormous practical
considerations to be overcome before it could fly. None are deal-killers,
but the sum of them is quite a bit of development work to assure production
capability. Mostly, concerns center on the 1) structural capability of the
rotors, which have virtually no hinge (about 50% hinge offset) and 2) the
ability to stop/stow and redeploy while airborne, with the tremendous
stresses and dynamic changes inherent in that trick. The X-wing tried that
(with a larger rotor) and was never successful, in the end.
Certainly, the Diskrotor tries to win back some low disk loading, a very
good first step!

Hello Mr. Lappos

Would it be fair to toss a fourth rotor configuration in to the
competition?

How about the Side-by-Side Kamov KA-22 "Vintokryl:

http://www.vstol.org/wheel/VSTOLWheel/KamovKa-22.htm

~ Speed of 192 knots [record]

~ Payload of 36,343 lbs [record]

~ Gross weight of 65,036 lbs

This is a 44-year-old helicopter. Just think of what could be done with
today's engines and composite materials.

I think that it's a slam-dunk for the Vintokryl.
