X2 Technology Demonstrator Achieves 225 Knots
Sikorsky's X2 Technology demonstrator unofficially broke the
speed record for rotorcraft on Monday, achieving a maximum speed of
225 knots in a one-hour test flight at the Development Flight
Center.

X2 Technology demonstrator Chief Pilot Kevin Bredenbeck executed
the successful record-breaking test flight. The previous record for
a 3,500 kg class of rotorcraft - 216 knots - was set by a Westland
Lynx in the mid-1980's. "The X2 Technology demonstrator's latest
flight is continuing to push the speed envelope, successfully
flying approximately 50 knots faster than a traditional
helicopter," said Jim Kagdis, Program Manager, Advanced Programs.
"Vibration levels and aircraft performance have continued to meet
or exceed our expectations, so we are pleased to report that all
systems are 'go' in our mission to achieve a 250-knot cruise speed
later this year."
In the demonstrator's previous flight, a new tail configuration
was incorporated to decrease pilot workload as the aircraft speed
is increased, improving the overall aircraft handling qualities.
Mark Miller, Sikorsky Vice President of Research & Engineering,
said, "The X2 Technology program is one of our Sikorsky Innovations
initiatives to develop and mature the technologies, products and
processes that will redefine the future of vertical flight. With
each successful test flight, the X2 Technology demonstrator is
carrying this forward and writing a new page in aviation
history."
The X2 Technology demonstrator combines an integrated suite of
technologies intended to advance the state-of-the-art,
counter-rotating coaxial rotor helicopter. It is designed to
demonstrate that a helicopter can cruise comfortably at 250 knots
while retaining such desirable attributes as excellent low-speed
handling, efficient hovering, and a seamless and simple transition
to high speed.
The X2 Technology program began in 2005 when Sikorsky first
committed resources and full funding for the program's
development.
