Unique Rotorcraft Development Program Seen As Sikorsky R&D
Benchmark
Few (if any) rotorcraft development programs have earned the
intense interest and scrutiny devoted to the Sikorsky X2 Coaxial
Pusher concept. About as unique as a rotorcraft gets these days,
this program has set the heli world on its ear with the promise of
a viable helo design that could conceivably be put into service
within just a few years and readily stomp through 250 knots, in the
process.
