Juan de la Cierva
Spanish inventor of the autogyro and pioneer of rotor-wing flight.
Last updated
He was born into a wealthy aristocratic family on 21 September 1895 and died in a plane crash on 9 December 1936.[1][2][3]
Life and work
He earned a civil engineering degree and moved to the United Kingdom in 1925, establishing the Cierva Autogiro Company with Scottish industrialist James G. Weir.[2] In 1919 he began considering using a rotor to generate lift at low airspeed to eliminate stall risk.[2] Early failures involved unbalanced rolling movement from dissymmetry of lift between advancing and retreating blades.[2] He died when a KLM DC-2 exploded after hitting a house near Croydon Airfield on 9 December 1936.[3]
What the cited sources add
The programme offers 350 contracts for doctors at public and private R&D centres.[4] These contracts last three years, unlike the five-year Ramón y Cajal programme.[4] Researchers may apply to both programmes but cannot request changes if hired under the Juan de la Cierva scheme.[4] Applicants must have spent at least 12 months at R&D centres different from their host institution after earning their doctorate.[4]
