	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.
		After four years of experimentation, la Cierva developed the articulated rotor which resulted in the world's first successful flight of a stable rotary-wing aircraft in 1923.
		De la Cierva was born in Murcia, Spain to a wealthy family.

	Autogyro History invented in the early 1920s by Juan de la Cierva
		The autogyro (autogiro), invented in the early 1920s by Juan de la Cierva, a Spanish civil engineer-turned aeronautical engineer, has had a chequered career but is now destined to be the aircraft of the future.
		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.

		Juan de la Cierva, a Spanish engineer and aeronautical enthusiast, invented the first successful rotorcraft, which he named autogiro in 1923.
		Juan de la Cierva This success eventually became well known and after further limited Autogiro development in Spain, la Cierva accepted an offer from Scottish industrialist James G. Weir to establish the Cierva Autogiro Company in England following a 20 October 1925 demonstration to the British Air Ministry at Farnborough.

	Original Artwork: David K. Stone: Juan de la Cierva
		Juan de la Cierva's first plane, a tri-motor, crashed after three successful flights, but the accident inspired this pioneer of aviation to design an aircraft that didn't depend on speed to remain airborne.
		Naturally, de la Cierva turned to the helicopter, which at the time was only a theory, but he soon realized that it was far too complicated for his purposes.
		After considerable study, de la Cierva realized that the only solution to his flight problems was an airplane with an autogiro that provided aerodynamic lift.

	Cierva, Juan de la (Site not responding. Last check: 2007-11-03)
		In trying to produce an aircraft that would not stall and could fly slowly, he invented the autogiro 1923, the forerunner of the helicopter but differing from it in having unpowered rotors that revolve freely.
		Cierva was born in Murcia and studied engineering in Madrid.
		Cierva's first aircraft was a biplane bomber which stalled and crashed when tested 1919.

	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.

	Cierva C.8W (Site not responding. Last check: 2007-11-03)
		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.

	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.

		For example, Weber and his collaborators in Urbana, Rio de Janeiro and Göttingen demonstrated the possibility of destroying the infectivity of viruses without affecting their immunogenic capacity and have thus opened the possibility of developing viral vaccines that contain without covalent modification all the antigens present in the original virus.
		Las técnicas de polarización de fluorescencia desarrolladas por Weber han sido aplicadas en la resolución de numerosos problemas en biomedicina: diagnóstico de drogas y metabolitos en sangre, secuenciación de aminoácidos en proteínas y bases en ácidos nucleicos.
		Las publicaciones de Weber y colaboradores desde 1965 en adelante, han demostrado que la mayoría de las proteínas compuestas de subunidades pueden ser disociadas al aplicar sobre ellas presión hidrostática, iniciandose de esta manera una nueva metodología para el estudio de las proteínas oligoméricas, metodología que ha influenciado areas como la fisiología y la patología.

	AUTOGIROS (Site not responding. Last check: 2007-11-03)
		The autogiro, which has a propellor for forward flight and self-rotating blades for lift, instead of powered rotating blades, as in a helicopter, was invented by Juan de la Cierva, who received a Spanish patent for it on August 27, 1920.
		His Cierva Autogiro Company produced these aircraft in the United Kingdom, where he had moved to, in 1925, and in 1929 the Pitcairn-Cierva Autogiro Company produced them in the United States of America.
		Juan de la Cierva was killed in the crash of a KLM DC-2 airliner, during its takeoff from Croydon Airport, in foggy weather, on December 9, 1936.

	The Contributions of the Autogyro
		This Pitcairn PAA-1 autogiro was flown at Langley for the NACA investigation of an experimental cantilevered three-bladed rotor.
		A Cierva autogyro was developed with a device to produce a vertical "jump" takeoff.
		Cierva autogyros did see some limited service in the armed forces of France, the Soviet Union, and Japan for forward observation and artillery spotting during World War II.

	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.

		I had seen the Cierva Autogyro flying during the war and though very young at the time this unique aircraft stayed in my memory.
		Juan de la Cierva, the Spanish pioneer of rotary winged aircraft brought his first successful machine to Britain in 1923 at the invitation of our Air Ministry and gave a demonstration at Farnborough.
		By 1936 vertical take-off was achieved but unfortunately in a fixed winged aircraft crash at Craydon airfield Juan de la Cierva lost his life.

		"Although de la Cierva's autogiro was still not a direct-lift machine and could not hover, it required only minimal forward airspeed to maintain flight.
		Juan de la Cierva proved that his autogiros were very safe and essentially stall-proof, and because of their low speed handling capability, they could be landed in confined areas." -from Evolution of Helicopter Flight by Professor J. Gordon Leishman.
