WARNING – The carbon monoxide level would be increasing dramatically in the Moscow region as well as in the capital center. According to some sources, hotspots rose up to 564. Italy and Ukraine promised aircraft to smother fires. France reportedly is about to provide some help as well.
The Sikorsky X2 Technology demonstrator reportedly broke the speed record for rotorcraft on Monday at a maximum speed of 225 knots (417 km/h).
The previous record had been set by Trevor Egginton on a Westland G-Lynx at a speed of 216 kts (400 km/h) on August 11, 1986. The fly-by-wire X2 helicopter was flown by Kevin Bredenbeck. Unfortunately, the test flight performance was not officially.
With a counter-rotating coaxial rotor, and its brand new tail configuration, the X2 is more maneuverable as the helicopter gains in speed. Moreover, the X2 would be excellent at low-speed handling as well as hovering.
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 that a helicopter can cruise comfortably at 250 knots while retaining such desirable attributes as excellent
Thanks to its integrated auxiliary propulsion system – coaxial pusher prop concept, and to other assets among which its reduced hub drag, the Sikorsky X2 prototype should exceed the 250-knot benchmark (463 km/h)!
