Sikorsky Aircraft yesterday unveiled its X2 technology demonstrator here at Heli-Expo, with hordes of attendees surrounding the black-shrouded helicopter before it was revealed in a cloud of smoke and lights at the company’s booth (No. 1641). What emerged was a sleek-looking, two-pilot ship with a contra-rotating coaxial main rotor and an “aero propeller” in place of the tail rotor.

Is it a low-flying airplane or a high-flying boat? You won’t be seeing one of these flying over the Kansas prairie, but if you need to travel over the high seas in the future, you may end up in one of Flightship Ground Effect’s wing-in-ground-effect (WIG) craft.

The UK took a step toward airborne network-centric warfare this month when it confirmed that the Tactical Information Exchange Capability (TIEC) would be added to Royal Air Force Tornado GR4 and Harrier GR9 combat aircraft. General Dynamics UK is the key provider of TIEC, which allows ground troops to transmit the coordinates of targets that they have identified into the cockpits of RAF Harrier GR9 and Tornado GR4 aircraft.

Sikorsky’s X2 technology dem-onstrator could fly by year-end, according to Peter Grant, Sikorsky’s director of advanced programs. The X2 is a coaxial rigid-rotor compound helicopter designed to achieve forward speeds up to 250 knots, and at that clip it would become the world’s fastest helicopter. The current helicopter speed record of 217 knots (set by a Westland Lynx) has stood for more than 20 years.
