Warplanes: Sikorsky Does It Again

“Sikorsky Aircraft, which produced the first service-ready American helicopter in 1942, and more recently the UH-60, has sought to assert its design dominance once more by developing a new helicopter design that produces record breaking speed (417 kph/288 mph). The new design is actually evolutionary, using coaxial rotors (that is two sets of rotors, one above the other with the props going in opposite directions and eliminating the need of a rear propeller to keep the aircraft from spinning) and a pusher prop in the rear. But there is also extensive use of new rotor design and software operated controls. The new design not only produces high speeds, but, more importantly, enables operation with heavy loads at high altitudes (think Afghanistan).”
