Cliff McKeithan hey, Cliff! thats the plan. tiltrotors have their own acoustic peculiarities, for which my paycheck is grateful. the bottom line is, as usual, capital. not only for our end (i.e. prediction method development, model and full-scale testing, etc.) but also to create the market for the production vehicles. we're now in a wobbly state; we have existing noisy helicopters in service, and an increasing understanding on noise reduction, but no impending design projects on which to apply it. Slick Willie sez he's for infrastructure spending, so let's hope that includes rotorcraft and short-haul. our problem is we're not glamorous enough. we don't have snappy acronyms and "space-camps" and all that. and since Congress has Nat'l Airport in their front yard they probably don't appreciate the air transport bottlenecks which are developing. -- |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| | Devon Prichard I haven't lost my mind; | | Senior Gofer its backed up on tape somewhere.| | Lockheed Engineering & Sciences Co. | | prichard@devon.larc.nasa.gov | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
