Dave,
From here:
Sikorsky X2 Technology
it says:
“The X2 Technology demonstrator program set out to accomplish four key performance objectives: low single pilot work load, low vibration, low acoustic signature, and speed – defined as cruise at 250 knots,” said Jim Kagdis, program manager for Sikorsky’s Advanced Programs. “There was a fifth key objective that remains a driving force to all that we do at Sikorsky: to preserve the legacy and pioneering spirit of our company founder, Igor Sikorsky, and to educate and inspire the next generation of engineers and aviation professionals. The Collier Trophy exemplifies this fifth objective, so it is hugely rewarding for the team to stand recognized for upholding the basic tenets on which Sikorsky Aircraft was founded. I am extremely proud of the team and our accomplishment.”
So to enumerate those goals from the above:
1) Low pilot workload
2) Low vibration
3) Low acoustic signature
4) 250 kts
5) Inspire the next generation
