A gyrocopter, also known as a gyroplane, is a type of aircraft that uses a rotor for lift and an engine-driven propeller for thrust. Unlike a helicopter, the rotor of a gyrocopter is not powered; it spins freely in the airflow, allowing the aircraft to achieve lift through autorotation. This design makes gyrocopters stable and easy to fly, often requiring less runway space for takeoff and landing. Gyrocopters are typically smaller and lighter than traditional airplanes, making them suitable for recreational flying and pilot training. They can be used for various purposes, including aerial photography and agricultural monitoring. Their unique design and capabilities have made them popular among aviation enthusiasts and hobbyists.
