Re: V22 Osprey
Graviman,
The cost for an X2 might be 10% more than a regular helo of the same general size, and the payload might be 10% less, due to the increased empty weight for the "extra" rotorhead and the auxiliary propulsion/propellor.
Also, the cruise fuel flow at 240-ish would be higher than a tilt rotor because the rotor is just not as efficient as a wing at high speed.
So the X2 would take off with about 50 to 75% more payload than a tiltrotor, but would burn more fuel per mile, so the range would be no better, and maybe worse. Devilish tradeoffs, these.
