When a company claims to have solved a challenge that has bedeviled its industry for years, it must be ready to prove that its idea will really fly. And that, quite literally, is what Sikorsky Aircraft is prepared to do. A leader in the design and manufacture of advanced helicopters for commercial, industrial, and military use, Sikorsky has used new technology to help significantly improve the performance of the conventional coaxial rotor, a stacked pair of high-performance counter-rotating rotors. The company is now preparing to demonstrate its new coaxial rotor, known as X2 Technology™ demonstrator*, with the world of aviation as its audience. Sikorsky is also hard at work applying its X2 Technology solutions to practical aviation challenges, as it perfects conceptual designs of two military heavy lift aircraft that employ the suite of X2 Technology solutions.
