Sikorsky X2
The Sikorsky X2 Demonstrator is an experimental compound co-axial helicopter under development by Sikorsky Aircraft.
Development
Sikorsky will incorporate decades of company research and development into X2 Technology helicopters, including: the S-69/XH-59A Advancing Blade Concept Demonstrator which showed high speed was possible with a coaxial helicopter and auxiliary propulsion, the Cypher UAV which expanded company knowledge of the unique aspects of flight control laws in a fly by wire aircraft that employed coaxial rotors, and the RAH-66 Comanche, which developed expertise in composite rotors and advanced transmission design.[1]
The X2 first flew on 27 August 2008 from Schweizer Aircraft's facility at Horseheads, New York. The flight lasted 30 minutes and began the flight test program.[2]
On 4 May 2009, Sikorsky unveiled a mock-up of a Light Tactical Helicopter derivative of the X2.[3]
