![]() In zero-wind conditions, it takes very little forward speed to generate enough lift for a gyroplane to take off and given enough of a headwind, they can just about lift off vertically. Instead, forward airspeed keeps them rotating enough to provide lift, and the free-spinning top rotor can do this well enough to autorotate gently to the ground in many power-out situations. Much of their lift is provided by a large top rotor, similar to that on top of a helicopter, but during flight, the rotor's not powered by the engine or motor. ![]() Gyroplanes offer an interesting middle ground between airplane and helicopter designs. It's a two-seat design mainly targeted at personal use, but the company claims it'll soon scale up to a certified six-seater for air taxi purposes. Germany's Fraundorfer Aeronautics has unveiled its Tensor 600X gyroplane at the European Rotors show.
