Also, unpowered rotors used in autogyro, gyrodyne, and derived concepts do not need a tail rotor either, although nearly all models that utilize this concept of propulsion do need a second prop in one way or another to drive them forward to begin with.

* In Hayao Miyazaki's 1979 anime film, The Castle of Cagliostro, Count Cagliostro utilizes an autogyro, notably against Lupin and company when they attempt to escape his castle residence with Clarisse in tow.

The film ends with minor characters chasing Fields as he drives Peggy Hopkins Joyce in his American Austin ( the smallest car sold in America at that time ) through the function rooms of the hotel and up and down the stairs, to drive the car into the hold of his autogyro and take off.

The film, due for release in 2011, features Wallis demonstrating several of his autogyro designs.

* January 17 – Juan de la Cierva invents the autogyro, a rotary-winged aircraft with an unpowered rotor.

During these projects he worked with the inventor of autogyro, Juan de la Cierva.

De la Cierva's autogyro used an airplane fuselage with a forward-mounted propeller and engine, a rotor mounted on a mast, and a horizontal and vertical stabilizer.

Less than a decade after the development of the first practical rotorcraft of any type with the autogyro, in the Soviet Union, Boris N. Yuriev and Alexei M. Cheremukhin, two aeronautical engineers working at the Tsentralniy Aerogidrodinamicheskiy Institut ( TsAGI,, ), constructed and flew the TsAGI 1-EA single rotor helicopter, which used an open tubing framework, a four blade main rotor, and twin sets of 1. 8-meter ( 6-foot ) diameter anti-torque rotors ; one set of two at the nose and one set of two at the tail.

An autogyro ( from Spanish autogiro ), also known as gyroplane, gyrocopter, or rotaplane, is a type of rotorcraft which uses an unpowered rotor in autorotation to develop lift, and an engine-powered propeller, similar to that of a fixed-wing aircraft, to provide thrust.

An autogyro is characterized by a free-spinning rotor that turns because of passage of air upward through the rotor.

The vertical component of the total aerodynamic reaction of the rotor gives lift for the vehicle, and sustains the autogyro in the air.

Whereas a helicopter works by forcing the rotor blades through the air, pushing air downwards, the autogyro rotor blade generates lift in the same way as a glider's wing by changing the angle of the air as it moves upwards and backwards relative to the rotor blade.

The hydrogen peroxide rockets are light-weight, inexpensive, reliable, noisy, and they transform the autogyro into an aircraft that has almost all the advantages of a helicopter at a fraction of the helicopter cost.

Turning the rockets on and off periodically generates horizontal thrust, which enables the autogyro to maneuver precisely before vertical landing.

His fourth design, the C. 4, made the first documented flight of an autogyro on 17 January 1923, piloted by Alejandro Gomez Spencer at Cuatro Vientos airfield in Madrid, Spain ( 9 January according to Cierva ).

The flapping hinges allowed each rotor blade to flap, or move up and down, to compensate for dissymmetry of lift, the difference in lift produced between the right and left sides of the rotor as the autogyro moves forward.

Britain had become the world centre of autogyro development.

The U. S. industrialist Harold Frederick Pitcairn, upon learning of the successful flights of the autogyro, had previously visited De la Cierva in Spain.
