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.^[2]

Specifications

Artist conception of a potential armed high-speed escort/attack variant of an X2 aircraft. X2 technology is envisioned to be applied to a wide range of typical rotorcraft roles.
