Juan de la Cierva designed a new rotor with a second linkage on the hub to correct the overstrain to eliminate cyclic stresses. To the existing one of abatement that eliminated the problem of lift asymmetry, a second one was added, which was designated as a drag joint , which allowed the blade to oscillate in the plane of rotation.
Juan de la Cierva's work on rotor-wing dynamics made possible the modern helicopter, whose development as a practical means of flight had been prevented by a lack of understanding of these matters. The understanding that he established is applicable to all rotor-winged aircraft; though lacking true vertical flight capability, work on the ...
Juan de la Cierva's first British-built autogyro was the C.8 design.It and some other designs were built in conjunction with Avro.The pre-war Cierva C.30 proved popular. . Nearly 150 were built under licence in the United Kingdom by Avro, in Germany by Focke-Wulf, and in France by Lioré-et-Oliv
The Cierva C.3 was an experimental autogyro built by Juan de la Cierva in Spain in 1921. [citation needed] It was based on the fuselage of a Sommer monoplane, and was actually completed and tested before that aircraft. The C.3 utilised a single, three-bladed rotor in place of the coaxial double rotor tested on the C.1.
De la Cierva's first successful autogyro, the Cierva C.6, used an Avro 504 fuselage, and this led to a long and close collaboration between de la Cierva and Avro from 1926 onwards, with de la Cierva providing the rotor design, and Avro the airframe from designs that often appeared as both fixed-wing and rotary aircraft. There was a long series ...
Between 1933 and 1936, de la Cierva used one C.30A (G-ACWF) to test his last contribution to autogyro development before his death in the crash of a KLM Douglas DC-2 airliner when taking off at Croydon Airfield in England on 9 December 1936. To enable the autogyro to take off without forward ground travel, Cierva produced the "autodynamic ...
Diagram of fully articulated main rotor head. Juan de la Cierva developed the fully articulating rotor for the autogyro. The basis of his design permitted successful helicopter development. In a fully articulated rotor system, each rotor blade is attached to the rotor hub through a series of hinges that let the blade move independently of the ...
The Cierva C.6 was the sixth autogyro designed by engineer Juan de la Cierva, and the first one to travel a "major" distance. Cierva , the engineer responsible for the invention of the autogyro , had spent all his funds on the research and creation of his first five prototypes .
