Sikorsky Aircraft unveiled its X2 Technology Demonstrator Aircraft Sunday at Heli-Expo in Houston. The counter-rotating coaxial rotor design is aimed at delivering the high-speed cruise while keeping the low-speed handling, hovering and autorotation safety characteristics that operators want. "The X2 Technology Demonstrator is an integrated suite of technologies intended to advance the state-of-the-art, counter-rotating coaxial rotor helicopter," said Sikorsky President Jeffrey Pinot. "As we continue to work to prove out and mature the technologies that will allow the X2 Technology Demonstrator to become a viable product, we are focused on testing its limits and finding out where this technology will take us."
