Cefoskey, I'm actually slightly suprised Kamov haven't thought about ABC technology before. It's a logical next step from coaxial. I guess this just means that the time is right for helicopter cruise/dash speeds to go up. Post credit crunch that is.
Has Kamov done any development into the high effective hinge offset blades? I can imagine this being a greater challenge for such a large machine. The alternative would be to accept advancing blade compressibility limitations or an increase in coning angle. Either way KA-92 will not be competing with S-92 instantly...
