Whereas a helicopter works by forcing the rotor blades through the air, drawing air from above, the autogyro rotor blade generates lift in the same way as a glider's wing, by changing the angle of the air as the air moves upward and backward relative to the rotor blade. A separate propeller provides forward thrust and can be placed in a puller configuration, with the engine and propeller at the front of the fuselage, or in a pusher configuration, with the engine and propeller at the rear of the fuselage. The downward component of the total aerodynamic reaction of the rotor gives lift to the vehicle, sustaining it in the air. Principle of operation The rotor head, pre-rotator shaft, and Subaru engine configuration on a VPM M-16 autogyroĪn autogyro is characterized by a free-spinning rotor that turns because of the passage of air through the rotor from below. Late-model autogyros patterned after Etienne Dormoy's Buhl A-1 Autogyro and Igor Bensen's designs feature a rear-mounted engine and propeller in a pusher configuration.

The success of the Autogiro garnered the interest of industrialists and under license from de la Cierva in the 1920s and 1930s, the Pitcairn & Kellett companies made further innovations. Gyroplane was later adopted as a trademark by Bensen Aircraft. Burke Wilford who developed the Reiseler Kreiser feathering rotor equipped gyroplane in the first half of the twentieth century. The term gyrocopter (derived from helicopter) was used by E. De la Cierva's Autogiro is considered the predecessor of the modern helicopter.

The term Autogiro became trademarked by the Cierva Autogiro Company.

The aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller. He first flew one on 9 January 1923, at Cuatro Vientos Airport in Madrid. It was originally named the autogiro by its Spanish inventor and engineer, Juan de la Cierva, in his attempt to create an aircraft that could fly safely at low speeds. While similar to a helicopter rotor in appearance, the autogyro's unpowered rotor disc must have air flowing upward across it to make it rotate.įorward thrust is provided independently, by an engine-driven propeller.

A modern, closed-cabin, pusher-propeller autogyro in flightĪn autogyro (from Greek αὐτός and γύρος, 'self-turning'), or gyroplane, is a class of rotorcraft that uses an unpowered rotor in free autorotation to develop lift.
