A gyroplane, also known as an autogyro, is a type of aircraft that uses a rotor to lift off the ground and traditional propellers for forward thrust. Some synonyms for this unique aircraft include gyrocopter, gyroplane, autogiro, and rotaplane. The term gyrocopter was originally coined by Igor Sikorsky, the famous helicopter designer, and became popularized in the United States. Autogiro, on the other hand, was the term used by the Spanish company that first developed the concept in 1923. Rotaplane is a more recent term that is primarily used in Europe. Despite their different names, all of these aircraft share similar features and capabilities, making them an exciting and innovative alternative to traditional airplanes.
