Autogyro History and Theory Cierva was born in Murcia, Spain, September 21, 1895. One of the props for the opera was a windmill with hinged blades. Cierva's solution for this problem was to design the tail in such a way that it would deflect the slipstream from the propeller up into the rotor. www.jefflewis.net /autogyros.html   (6509 words)

Juan De La Cierva Juan de la Cierva, born on September 21, 1895, in Murcia, Spain, was an aeronautical engineer who invented the autogiro, an aircraft that combined the capabilities of a conventional airplane and the helicopter. His aircraft were further developed by the Cierva Autogiro Company of Great Britain, as well as by U.S. and various continental companies. Cierva died in an airplane crash on December 19, 1936, near London, England. www.centennialofflight.gov /essay/Dictionary/cierva/DI17.htm   (286 words)

Cierva C.8W Cierva constructed six different C.8 configurations, all of which were experimental testbeds built to test improvements in autogiro technology before a production model, the C.19, was to appear in 1929. After Cierva confirmed that this would not be an issue, Pitcairn agreed to purchase a new C.8 with the Wright engine. By the end of 1929, a three-degree reduction in the angle of incidence of the autogiro's fixed wing reduced this hazard significantly by altering the attitude of the aircraft in flight. www.nasm.si.edu /research/aero/aircraft/cierva_c8w.htm   (2660 words)

Autogiros, Gyroplanes, & Gyrocopters Cierva's solution was to hinge the rotor blades to the hub, allowing them a degree of travel up-and-down and back-and-forth. Cierva had already considered the idea but was using a rope pull starter to get the rotor up to speed. The first was the death of Cierva in the crash of a Dutch Douglas DC-2 airliner in England on 9 December 1936. www.vectorsite.net /avgyro.html   (4653 words)

Cierva C30 The Cierva C. autogiro first flew in 1934 and was ordered by the RAF as the Avro Rota. The Cierva C30 is based on the Rotorshape mechanic which has proven to be one of the best system on the market. The Cierva C30 is available in two paint schemes, one is Spain the other France. www.icare-rc.com /cierva-c30.htm   (150 words)

Chapter 5: Praetorian Politics in Liberal Spain As La Cierva had anticipated, the remaining junteros, except for Herrero, quickly closed ranks against Márquez, whose petition for reinstatement before the assembly of regional representatives was politely and firmly rejected on January 7. As temporary head of the postal service, La Cierva was empowered to act unilaterally; with his usual vigor, he mobilized the reserves to replace the absent employees and dissolved the Corps of Postal and Telegraph Workers, while the rest of the government looked on apprehensively. Outraged at what he considered to be a betrayal, La Cierva resigned in protest on March 19, and the rest of the cabinet, bereft of its strongest member, followed suit, opening up a crisis as severe as that of the previous autumn. libro.uca.edu /boyd/chapter5.htm   (9484 words)

Juan de la Cierva Summary Juan de la Cierva (21 September 1895 – 19 December 1936) was a Spanish aeronautical engineer and pilot. His most famous accomplishment was the invention in 1919 of the Autogiro, a type of aircraft that later came to called an autogyro.

Autogyro History invented in the early 1920s by Juan de la Cierva Cierva's original name for the aircraft was Autogiro, indicating that the rotor turned by autogiration. Cierva's development of the rotor system was instrumental in, even crucial to, the success of the helicopter. Cierva pursued this design after one of his early aircraft, a tri-motor bomber, crashed during trials. www.gyropilot.co.uk /autogyro_history.asp   (503 words)

The History of Gyroplanes   (Site not responding. Last check: ) Pondering the crash, Cierva's brilliant insight was to see the wing differently ---aircraft stalled when the air passing over the wing failed to generate enough lift at slow speed - he reasoned that stall could be effectively eliminated if the wing itself moved independently of the aircraft. Cierva stated that the first flight of his CA Autogiro was on January 9, 1923 at Getafe airfield outside Madrid when (Calvary) Lieutenant Alejandro G6mez Spencer guided the craft in taxi tests during which the craft became airborne. Cierva died in the crash of a KLM DC-2 bound for Amsterdam from the airport at Croydon Aerodrome, London on December 9, 1936. www.groenbros.com /history.php   (2659 words)

Of Autogyros and Dinosours   (Site not responding. Last check: ) Cierva explains that in 1918 a severe accident after stalling a conventional airplane led him to search for the means of stall prevention that was eventually incorporated in his invention. It was ironic that Cierva died in the crash of a fixed-wing airliner. Cierva predicted a 7-ton payload and speed of 200 mph for his autogyros, which at the time flew at 115 mph with a gross weight of 3,500 pounds. www.airpower.maxwell.af.mil /airchronicles/apj/apj88/temple.html   (5603 words)

The Invention Of The Helicopter La Cierva's autogyros were essentially the fuselage of a fixed-wing aircraft with a rotor mounted on top. La Cierva established a factory for building autogyros in Britain, and the "flying windmill" proved to be something of a sensation. La Cierva was killed in an airliner crash near London in December 1936. www.faqs.org /docs/air/avheli.html   (7629 words)

Juan de la Cierva - Wikipedia, the free encyclopedia Juan de la Cierva (21 September 1895 – 19 December 1936) was a Spanish aeronautical engineer and pilot. He died in an airliner accident near London at the age of 41. As airspeed increased, propellor power increased while rotor power automatically decreased which reduced rotor collective pitch to autorotative angle with the rotor remaining parallel to the flightpath. en.wikipedia.org /wiki/Cierva   (344 words)

Former Pages from the North East Aircraft Museum With it the spell was broken and de la Cierva developed further types in quick succession. On the invitation of the British Air Ministry, he demonstrated his C 6A type, (which was built from the fuselage of an Avro 504K trainer) at Farnborough in October 1925. In 1926, de la Cierva settled in Britain and, with the aid of Air Commodore Lord Weir, he founded the Cierva Autogyro Company in Hanworth. www.neam.co.uk /helicopters/cierva.html   (610 words)

Avro Rota in Detail Juan de la Cierva was instrumental in the development of the autogyro. The Cierva C.30A was an important step forward, as the rotor could be spun up by the motor, shortening the take-off run to some 30 m, and the rotor disc could be tilted by the pilot in order to manoeuvre the aircraft. After the war K4232 was sold to the Cierva Autogiro Co, who sold it on to Helikopterflyg AB in Sweden, who flew it with the registration number SE-AZB. ipmsstockholm.org /magazine/2004/12/stuff_eng_detail_avro_rota.html   (563 words)

Birth of Television Agency 'Rome Reports' - Catholic Online De la Cierva is a professor at the Faculty of Institutional Social Communication of the Pontifical University of the Holy Cross. De la Cierva: Because he is completely natural: He does not represent a role nor does he say what his audience might like to hear, but speaks according to his conscience. But the Catholic broadcasting stations are interested in everything that happens in the Holy See: ceremonies, news on causes of beatification and canonization, documents, "ad limina" visits of the bishops of their countries, etc. And all this reported with Catholic sensibility. www.catholic.org /featured/headline.php?ID=1036   (1429 words)

The History of Gyroplanes Spanish inventor Juan de Ia Cierva built the first "Autogyro" in 1923 by combining a conventional fixed wing aircraft's engine and fuselage with an overhead mast and three bladed rotor system. These problems were solved on Cierva's fourth aircraft, dubbed the "0-19 Autogyro," through the addition of a flapping hinge point near the rotor hub which would allow for the rotor blades to equalize the lift between the advancing and retreating blades. The C-19 Autogyro was first demonstrated in England in 1925 for a group of military officers who were impressed with The aircraft's performance and maneuverability. pw2.netcom.com /~tomt393/History.html   (753 words)

Juan De La Cierva At the age of 15, Juan De La Cierva, with two friends, constructed a glider of his own design and began, through trial and error, to learn about aircraft design. Beginning with the helicopter concept known by experimentalists for some time, he conducted many tests of various configurations finally concluding that true helicopter flight was not technically feasible with the state of the art of that time. It was Cierva's development of rotor blade design and articulated rotor blades, which played a major role in the first successful helicopter in 1936. www.allstar.fiu.edu /aero/cierva.htm   (244 words)

Autogyros Here is a picture of one of Cierva's original autogyros from www.gettyimages.com.

Opus Dei by D. Ricardo de la Cierva Hoces We are selectively quoting the portions from Chapter 9 of de la Cierva's book which are key to understanding the true spirit of the Opus Dei explained by a friend and not a foe. de la Cierva's evaluation of The Prelature of the Holy Cross and Opus Dei is among one of the most balanced presentation of Opus Dei that we have encountered. Although de la Cierva identifies and discusses three key problems he perceives: (a) Elitist spirit; (b) Indiscriminate alliance with the enemies of God; and (c) Discretion [read "Secrecy"], de la Cierva fails to see that precisely those three components reveal the true Spirit of Opus Dei. www.mgr.org /delaCiervaTransl.html   (2202 words)

The Weir W-2 Autogyro- An AUTOGYRO by "Z" for Fiddlers Green In 1928 Cierva arrived in the United Kingdom and established his own company, of which Weir Ltd was main financiers of, with James G. Weir as chairman. Frank Courtney first saw a Cierva Autogiro (correct spelling of anything built under Cierva's authorization, including the Weirs) in Spain, and after a time suggested that Cierva bring a machine to England for demonstration. The Cierva brought to England was based upon an Avro fuselage, and Courtney helped arrange connections between Cierva and A.V. Roe, who's factory constructed many of the susequent 'giros for Cierva, most of which Courtney demonstrated. www.fiddlersgreen.net /AC/aircraft/Cierva-W2-autogyro/info/info.htm   (930 words)

Autogiro Cierva C8L-II Review by Rob Baumgartner (HR Model 1/72) The autogiro came about in 1919 thanks to Juan de la Cierva. He conceived of a rotor being driven by aerodynamic forces alone, with thrust being provided by an engine powered propeller. This Spanish engineer developed a number of designs, and his success eventually led him to establish the Cierva Autogiro Company. kits.kitreview.com /hr7349ireviewrb_1.htm   (547 words)
