In order to achieve this, he utilized the ability of a lifting rotor to autorotate, whereby at a suitable pitch setting, a rotor will continue to rotate without mechanical drive, sustained by the torque equilibrium of the lift and drag forces acting on the blades. Compre online Juan de la Cierva and His Autogiros, de Ord-Hume, Arthur W. J. G. na Amazon. Juan de la Cierva construyó en Madrid en 1920 su primer autogiro, el Cierva C.1, utilizando fuselaje, ruedas y estabilizador vertical de un monoplano francés Deperdussin de 1911, sobre el que montó dos rotores cuatripalas contrarrotatorios coronados por una superficie vertical destinada a proporcionar control lateral; la planta motriz era un motor Le Rhône de 60 CV. Hijo de Juan de la Cierva Peñafiel, empresario, abogado y político de don Alfonso XIII.. Mostró un gran interés por la aeronáutica, gracias a su abuelo, Ricardo Codorníu Stárico, quién le explicó porqué volaba un avión. The rotor was accelerated in no-lift pitch until the rotor speed required for flight was achieved, and then declutched. 21 września 1895 w Murcja, zm. El autogiro fue invención del ingeniero español Juan de la Cierva, quien desarrolló el rotor articulado que más tarde usarían los helicópteros (aunque es pasivo, este sistema diseñado por Juan de la Cierva compensaba la diferencia de empuje del aire batido, cuando la pala va adelante, con el batido, cuando va atrás, que hacía volcar tanto al autogiro como al helicóptero). El padre del autogiro fue el ingeniero español Juan de la Cierva Codorníu (1895-1936). Inventó el autogiro, aparato precursor del actual helicóptero. For six years he attended the Escuela Especial de Ingenieros de Caminos, Canales y Puertos in Madrid, Spain, where he studied theoretical aerodynamics. Dezember 1936 in der Nähe von London) war ein spanischer Ingenieur und Luftfahrtpionier.Seine Forschungen haben maßgeblich zur Entwicklung des Hubschraubers beigetragen, der den von ihm entwickelten Autogiro ab dem Zweiten Weltkrieg ersetzte. His most famous accomplishment was the invention in 1920 of the Autogiro, a single-rotor type of aircraft, a predecessor of today‘s helicopter. The company was set up to further the designs of Juan de la Cierva , a Spanish engineer and pilot, with the financial backing of James George Weir , a Scottish industrialist and aviator. Juan de la Cierva The Cierva Autogiro Company was a British firm established in 1926 to develop the autogyro . In 1928 an autogyro completed a journey of 4,800 kilometers over the British Isles, and on September 18 in the same year De la Cierva piloted his own C.8 from London to Paris, crossing the English Channel with French journalist Henri Bouché as a passenger. En 1912, y con tan solo 16 años, De la Cierva logró construir y hacer volar un avión biplano al que bautizó como 'El cangrejo', veinte años después del vuelo de los hermanos Wright. This major difficulty was resolved by the introduction of the flapping hinge. 1997: Irwin Fridovich e Joe Milton McCord, https://pt.wikipedia.org/w/index.php?title=Juan_de_La_Cierva_y_Codorniu&oldid=47977347, Atribuição-CompartilhaIgual 3.0 Não Adaptada (CC BY-SA 3.0) da Creative Commons. In 1925, he demonstrated his autogiro to the British Air Ministry at Farnborough, Hampshire, which was a great success, and resulted in an invitation to continue the work in the UK. En 1928 el autogiro completó un recorrido de 4.800 kilómetros por las islas británicas, y el 18 de septiembre del mismo año el propio De la Cierva pilotó su C.8 desde Londres a París, cruzando el Canal de la Mancha con el periodista francés Henri Bouché como pasajero. Cierva … Juan de la Cierva (21 September 1895 -- 9 December 1936) born in Murcia, Spain to a wealthy family, was a Spanish civil engineer and pilot. Following this, he entered a competition to design military aircraft for the government and built a biplane bomber with an airfoil (the part of a plane that provides lift) that he designed mathematically. Juan de la Cierva y Codorníu (ur. The same year, de la Cierva moved to England where, with the support of Scottish industrialist James G. Weir, he established the Cierva Autogiro Company. Before this could be satisfactorily achieved, De la Cierva experienced several failures primarily associated with the unbalanced rolling movement generated when attempting take-off, due to dissymmetry of lift between the advancing and retreating blades. With De la Cierva‘s autogiro, the rotor was drawn through the air by means of conventional propeller, with the result that the rotor generated sufficient lift to sustain level flight, climb and descent. His most famous accomplishment was the invention in 1920 of the Autogiro, a single-rotor type of aircraft, a predecessor of today ‘s helicopter. A Spanish engineer and aeronautical pioneer, Juan de la Cierva, developed the original “autogiro”.

O primeiro autogiro foi o C.4, desenvolvido e construído por Juan de La Cierva, tendo feito o primeiro voo em 9 de janeiro de 1923, pilotado pelo inventor no Aeroporto de Madrid de Cuatro Vientos. El autogiro de Juan De La Cierva volando en1923. El papel de Juan de la Cierva. In 1920, de la Cierva was just 25 years old when he began working on this strange aircraft: an airplane whose wings had been replaced by a freely rotating rotor driven by the relative wind. Required fields are marked *, The SciHi Blog is made with enthusiasm by. The autogiro was developed by Juan de la Cierva , and in 1923 it was the very first type of rotating-wing aircraft to fly successfully and demonstrate a useful and practical role in aviation, pre-dating the first successful flights with helicopters by about 15-years. On July 22, 1931, he landed the Cierva C.8—the first Autogiro flown in America—on the National Mall in front of the Smithsonian Institution, to be enshrined with other noteworthy aircraft. In addition to the name autogyro, they have been known as gyrocopters, gyroplanes, and autogiros. In a fixed-wing aircraft, lift is provided by the wing, thrust by the propeller. A intenção de Juan era projetar uma máquina que fosse capaz de se manter no ar mesmo se o motor deixasse de funcionar. In 1923, De la Cierva‘s first successful Autogiro was flown in Spain. Most important was the development of direct rotor control through cyclic pitch variation, achieved initially by tilting the rotor hub and subsequently by Raoul Hafner by the application of a spider mechanism that acted directly on each rotor blade. Juan de la Cierva was born in Murcia, Spain to a wealthy family. Esta página foi editada pela última vez às 11h22min de 10 de fevereiro de 2017. The autogiro was a major step toward those goals.[1]. As De la Cierva‘s autogiros achieved success and acceptance, others began to follow and with them came further innovation. In a very ironic twist of fate the man who spent the better part of his life to develop a safe aircraft would loose his own life in an aircraft accident. Engenheiro aeronáutico espanhol, inventor do "autogiro" em 1920, precedente do “Helicóptero” (helic = hélice, óptero = besouro). Juan de la Cierva was a Spanish pilot and engineer whose name remains intimately linked to the success of the autogiro. Cierva believed that fixed-wing aircraft were unsafe, so he experimented with a rotary-wing design.

On September 21, 1895, Spanish civil engineer and aviation pioneer Juan de la Cierva y Codorníu was born. At the outbreak of the Spanish Civil War in 1936, de la Cierva supported the forces of Francisco Franco, while his brother was executed by the Republican army in Paracuellos del Jarama. O helicóptero propriamente dito foi inventado pelo russo Igor Sikorsky em 1940, observando que, o autogiro de La Cierva decolava horizontalmente, e o helicóptero de Sikorsky, verticalmente. Although trained as a civil engineer, Cierva became interested in aviation early in his youth. This phenomenon was already known, and was available as a safety feature to allow controlled descent of a helicopter in the event of engine failure. Para isso usou dos conceitos do avião que utiliza uma força horizontal para decolar, mas, com asas rotativas que girassem independentes do motor para manter a sustentação no ar. He also wanted to develop an aircraft that needed only a short takeoff run and could slowly land in small areas. Juan de La Cierva y Codorniu, 1º conde de La Cierva (Murcia, 21 de Setembro de 1895 — Londres, 9 de Dezembro de 1936) foi um engenheiro aeronáutico espanhol. On the morning of 9 December 1936, de la Cierva boarded a Dutch DC-2 of KLM at Croydon Airfield, bound for Amsterdam, which during take off should stall and crash on the roof of a building at the end of the runway. Juan de la Cierva y Codorníu (1895 – 1936). De hecho, el padre de quien llegaría a ser el genial inventor del Autogiro, antes aludido sin más como don Juan, era el prestigioso político y abogado Juan de la Cierva Peñafiel, que no veía en principio con buenos ojos la trayectoria elegida por su hijo, prefiriendo para él una carrera jurídica más afín a la … 9 grudnia 1936 w Croydon) – hiszpański inżynier, konstruktor lotniczy i pilot.. Cierva już w wieku 15 lat zaczął budować szybowce-lotnie, na których wykonywał loty. At yovisto academic video searchyou can learn more about the history of early helicopters in a short documentary produced for Encyclopedia Britannica, now part of the Prellinger archive on Helicopters from 1953. The introduction of jump take-off was another major improvement in capability. Juan de la Cierva y Codorníu (* 21.September 1895 in Murcia; † 9. Aviation Pioneer Juan de la Cierva. De la Cierva’s work on rotor dynamics and control made possible the modern helicopter, whose development as a practical means of flight had been prevented by these problems. La vida de Juan de la Cierva como inventor es la historia del Autogiro, que concibió cuando tenía 24 años. Your email address will not be published. Fue construido por el ingeniero de caminos, canales y puertos, además de aviador Juan de la Cierva.El ingeniero murciano José Barcala, Pablo Díaz y Juan de la Cierva forman la sociedad B.C.D, que coincide con los apellidos de los tres miembros integrantes. Juan de la Cierva El Autogiro Juan de la Cierva nació el 21 de Septiembre de 1895, en Murcia. [2] Autogiros were used during the 1930s for military liaison, mail delivery, and agricultural purposes. In 1919 he started to consider the use of a rotor to generate lift at low airspeed, and eliminate the risk of stall. Although trained as a civil engineer, Cierva became interested in aviation early in his youth. After several successful experiments with aviation as a boy, he eventually earned a civil engineering degree. On September 18, 1928, he flew one of his autogiros (C.8) across the English Channel, and in 1930, he flew one from England to Spain. The plane was tested in May 1919, but it crashed when the pilot stalled it.[1]. Juan de la Cierva y Codorníu (Murcia, España, 21 de septiembre de 1895-Croydon, Reino Unido, 9 de diciembre de 19361 ) fue un inventor y científico aeronáutico español, ingeniero de caminos, canales y puertos y aviador.
