American
Sikorsky Aircraft Helicopter X2 Technology Demonstrator
at Paris Air Show 2011.
At
Paris Air Show 2011, the American Company Sikorsky presents
the X2 Technology Demonstrator. Sikorsky Aircraft Corp.
has developed the X2 Technology™ demonstrator intended
to advance the state-of-the-art of counter-rotating coaxial
rotor helicopters. In its high-speed configuration, X2 Technology
takes advantage of the full potential lift of a rigid coaxial
rotor and fully integrated propulsion to enable a helicopter
to cruise comfortably at 250 knots.

X2 Technology Demonstrator at Paris Air Show 2011
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 a helicopter can cruise
comfortably at 250 knots, while retaining desirable helicopter
attributes including excellent low speed handling, efficient
hovering and autorotation safety, and a seamless and simple
transition to high speed.
Among
the innovative technologies the X2 Technology demonstrator
employs are:
- Fly-by-wire flight controls
- Counter-rotating rigid rotor blades
- Hub drag reduction
- Active vibration control Integrated auxiliary propulsion
system
At traditional helicopter speeds, X2 Technology features
will provide improved lift through the efficiency of its
coaxial rotor, eliminating the need for a tail rotor.
To demonstrate the viability of X2 Technology features,
Sikorsky built an X2 Technology demonstrator with its *Light
Helicopter Division of Sikorsky Global Helicopters in Horseheads,
N.Y.
X2 Technology aircraft will hover, land vertically, maneuver
at low speeds, and transition seamlessly from hover to forward
flight like a helicopter. An integrated “pusher prop”
auxiliary propulsion system enables high speeds with no
need to physically reconfigure the aircraft in flight.
On Aug. 27, 2008, the program achieved first flight.
