X2 Helicopter Sets Unofficial Speed Record

X-2

August 5, 2010 —The Sikorsky X2 unofficially set the helicopter speed record on July 25, reaching a speed of 225 knots during a one-hour test flight. Since there was no representative from the Federation Aeronautique International (FAI) present, the Westland Lynx still holds the official record at 216 knots, according to flightglobal.com.

The X2 aims for an eventual speed of 250 knots, although chief pilot Kevin Bredenbeck thinks that higher speeds may be possible. The aircraft is entering the final two months of a yearlong testing phase and the company plans to add a new tail surface aimed to reduce drag and allow the aircraft to reach the goal of 250 knots.

 The X2 has a T800 engine and uses the advancing blade concept started with the XH-59 nearly 40 years ago. Sikorsky developed the X2 with the hopes of increasing the speed of the next generation.
