An autogyro is a type of aircraft that uses a free-spinning rotor to generate lift, while a conventional engine-driven propeller provides thrust. This design allows the autogyro to take off and land in shorter distances compared to traditional airplanes. The rotor's rotation is powered by the airflow as the aircraft moves forward, making it a unique hybrid between a helicopter and an airplane. Invented by Juan de la Cierva in the 1920s, the autogyro was developed to improve safety in flight. Unlike helicopters, autogyros can glide safely if the engine fails, thanks to their rotor system. This feature makes them appealing for various applications, including recreational flying and pilot training.
