X2 TECHNOLOGY™ Demonstrator Approaches First Flight


FARNBOROUGH INTERNATIONAL AIR SHOW, July 2008 – After three years in development and experimental testing, the first flight of Sikorsky Aircraft Corp.’s X2 TECHNOLOGY™ Demonstrator is “within reach,” James Kagdis, Program Manager, Advanced Programs, said today at the Farnborough International Air Show. Sikorsky, based in Stratford, Conn., USA, is a business unit of United Technologies Corp. (NYSE:UTX).

The X2 TECHNOLOGY Demonstrator has accomplished more than 14 hours of ground run testing and is progressing toward first flight.

“The Demonstrator has completed Phase 2 of ground run testing with blades on, and is in final build-up for first flight,” Kagdis said. “Customer feedback since tells us that X2 TECHNOLOGY has the potential to be applied to a broad range of missions. We are excited at the prospects of transforming vertical flight through this innovative technology.”

Sikorsky’s Schweizer Aircraft Corp. rapid-prototyping facility in Horseheads, N.Y., is preparing the X2 TECHNOLOGY Demonstrator for its first flight.

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 such desirable helicopter attributes as 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

Sikorsky Aircraft first announced the initiative to develop an integrated suite of technologies called X2 TECHNOLOGY in June 2005. The project is funded solely by Sikorsky.

Sikorsky Aircraft Corp., based in Stratford, Conn., USA, is a world leader in helicopter design, manufacture, and service. The company’s long commitment to safety and innovation is reflected in its mission statement: “We pioneer flight solutions that bring people home everywhere … every time™.“ United Technologies Corp., based in Hartford, Conn., USA, provides a broad range of high-technology products and support services to the aerospace and building systems industries.
