Helicopter maker successful in new tech tests.

Sikorsky Aircraft Corp., Stratford, CT, successfully completed the first flight of its X2 Technology Demonstrator, maneuvering the prototype aircraft through hover, forward flight, and a hover turn, in a test flight that lasted approximately 30 minutes.

The X2 Technology Demonstrator is designed to establish that a helicopter can cruise comfortably at 250 knots, while retaining such desirable helicopter attributes as excellent low speed handling, efficient hovering, and safe autorotation, combined with 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, all-composite rigid rotor blades;

* hub drag reduction;

* active vibration control; and

* an integrated auxiliary propulsion system.

The project is funded solely by Sikorsky. It is a subsidiary of United Technologies Corp.
