It's fut coins alsonotspringing up from specific improvementsin helicopter or other VTOL capability in the aerospace industry.Nor does it arise from any tech innovations Darpa sees on thehorizon. "We have seen in the community a few isolated and novelapproaches to addressing this problem but we're in danger ofsuffering an attrition in our technology bases, Bagai said. "Thisis an opportunity Darpa would like to put forth to advance thestate of the art, well beyond where we are today.
Good luck with that. Helicopters usually get faster by addingpower and messing with the rotor placements.See for instance,Sikorsky'sfunky' s-era designs.But that typically compromises their abilityto hover. Nor, Bagai conceded, have fixed-wing VTOLs cracked thespeed/hover/power problem. And the V- Osprey tilt-rotor hasenduredmorethan its fair share of challenges.
