WHAT IS A GYROPLANE / AUTOGIRO / AUTOGYRO / GYROCOPTER?
“GYROPLANE” is an official term designated by the Federal Aviation Administration (FAA) describing an aircraft that gets lift from a freely turning rotary wing or rotor blades, and which derives its thrust from an engine-driven propeller. Historically, this type of aircraft has been known as autogiro and gyrocopter. These early names and their variants were filed as trademarks. Gyroplanes derive lift from freely turning rotor blades tilted back to catch the air. The rushing air spins the rotor as the aircraft is thrust forward by an engine driven propeller. Early gyroplanes were powered by engines in a tractor (puller) configuration and were relatively heavy. Modern gyroplanes use pusher propeller and are light and maneuverable. With engine in the rear, the gyroplane has unobstructed visibility.
