Sikorsky's Successful X2 Demonstration

Sikorsky Aircraft Corp successfully ground tested the X2 with installed and spinning rotorblades using its X2 Technology Demonstrator program. The initial “blades-on” ground test was conducted last week. The ground tests are continuing at Sikorsky’s Schweizer Aircraft Corp rapid-prototyping facility in Horseheads, N.Y., in preparation for the X2 Technology Demonstrator’s first flight. The system will be used in diverse applications worldwide. 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 kt, 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. The X2 Technology Demonstrator employs: fly-by-wire flight controls; counter-rotating rigid rotor blades; hub drag reduction; and active vibration control. For related news
