In the first models a tail skid was used, which was only meant to support the B Upper rotor aircraft off the ground. Later it was replaced D Appeared in the original patent (C1 model), by a small wheel with directional capacity.

C30A model George Weir and the at the Getafe C Rotor and blades Subsequent more advanced models collaboration of the British airfield aircraft manufacturer I The blades are aerofoils and provide included an articulation in the rotor when in motion. The rotor is free moving head, which made these unnecessary. . It was responsible L for the development and 183 m (not motorised), and its speed of rotation depends on the relative speed of the air. L manufacture of The higher the rotational speed, the greater In the front, it had two non-directional fixed from the C8 model up to the lift. If the engine stops, the autogyro wheels that supported most of the weight of the C40 (the C1 to C7 A pioneer of Control surfaces glides and descends slowly thanks to the aircraft. Both wheels had brakes. were developed in ). The autogyro has 2 types of control surfaces. One of the the movement of the rotor. Depending control surfaces is the rotor, which, in addition to providing on the model and its evolution, the rotors M Engine lift, controls the roll by means of the lateral movement of had between three and five blades. The models had different engines depending the control stick (right-left). The other control surface is Except for in the C1 model, they all had on the version. The engine that was most directional, controlling the pitch with a longitudinal movement just one rotor. used by de la Cierva was the Le Rhône (forward-backward) of the control stick, and the yaw 9Ja (different versions), but he also used is controlled using pedals, by means of the rudder. D Control column Clerget, Woseley Viper, Armstrong Siddeley The flight attitude control stick controlled and Salmson engines. The first models were the inclination and angle of the rotors, not very powerful, with engines that were a secret invention that was about to change the course of aviation: a secret Thanks to its ability to fly slowly, the RAF used the autogyro to calibrate to calibrate the RAF used autogyro Thanks to its ability fly slowly, The autogyro which was the autogyro’s main control between 60 and 80 hp, but from the C8 st in the 21 century mechanism. they began to exceed 180 hp. The engines During the 1930s, Nowadays, new autogyro models did not power the rotor, as it is free moving. dozens of autogyros have been developed and E Cockpit However, in the more advanced models, the were used in the U.S. to marketed (single-seaters and engine had a rotor pre-launch system that mail from the two-seaters), and are mainly used allowed it to reach about 200 rpm while still rooftops of skyscrapers 1895 (, Spain) - 1936 (Croydon, United Kingdom) F for sports flying. However, there are For almost all the autogyro models on the ground, in order to facilitate take-off in , New York some companies that have taken up manufactured by Juan de la Cierva, he in just a few metres. and Chicago to their the original idea to create autogyros due to the operational respective . The design of INVENTOR, SCIENTIST, used the fuselage of existing aircraft, which advantages they offer (Bellcomm, Rotorvox, Gyro, ELA Girodinamics, CIVIL ENGINEER AND allowed him to reduce costs and focus N the autogyro arose Sprint, Xenon, Tercel, Lightning, J-RO, MTOsport, Spirit, etc.) AVIATOR on the development of the mobile parts of By means of its rotation, the propeller as a result of an the aircraft.
