  • PICTURE: Sikorsky's X2 Hits 181kt
    Posted by Graham Warwick 1:25 PM on May 25, 2010

    Sikorsky's X2 Technology high-speed helicopter demonstrator has reached 181kt on its way to the target of cruising at 250kt. The coaxial-rotor helicopter has been cleaned up for the high-speed runs, with rotor-hub fairings and retractable landing gear.

    Sikorsky says tests at its West Palm Beach, Florida, development flight center have revealed no show-stoppers. The 181kt mark, faster than most conventional helicopters can cruise comfortably, completes the third phase of flight tests. The fourth phase will take the X2 to 250kt.

    Sikorsky has already proposed a light tactical helicopter using the X2's technology suite to meet the U.S. Army's Armed Aerial Scout requirement to replace the OH-58D Kiowa Warrior. The company says it could develop the all-new helicopter by 2018.
