You better head for the bunker, grab yer Kevlar underwear.....sully the "Concorde"? Yikes...."Incoming!"
Hehehe, damn straight! I live in a country where we handed the space race over to Ariane, before it began (they are not technically minded in Westminster). Concorde is proof that we could still deliver cutting edge technology right up there with the Space Shuttle. The Apollo program also inspired a generation of engineers - and still does by the way!
My concern is that technically the V-22 is not the best approach for it's mission requirements.
Also, the (X-2) 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.
I imagine that the development of active blade twist, and rotors stable at low RRPMs, will go a long way to helping with this.
