After receiving his engineering degree, in 1918 he built the first trimotor airplane. Its crash in 1919 after a stall convinced him that aviation safety called for stall-proof aircraft that could make steep takeoffs and landings at slow speeds. He decided that only the wing and not thefuselage  should be used to maintain lift. He began experimenting with rotating-wing aircraft in 1920 and developed the autogiro as a more stable form of aircraft. His first attempts with rigid rotors were unsuccessful. He then applied the idea of mounting the blades to the hub of the rotor on hinges so they could flap. This would equalize lift on advancing and retreating sides of the rotor while in forward flight.</div> <div> His first successful flight with the autogiro took place on January 9 1923. The craft was equipped with a conventional propeller for forward flight and an articulated, or hinged, air-powered rotor blade that could be adjusted to balance lift. This technical breakthrough was necessary for the successful development of the helicopter, which ironically, replaced the autogiro around the time of World War II.</div> <div> Cierva moved to England in 1925. His aircraft were further developed by the Cierva Autogiro Company of Great Britain getting companies interested in converting standard aircraft into autogiros such as Comper and Avro, as well as by U.S. and various continental companies. They were used widely in France, Germany, Japan, and the United States until World War II, when the helicopter replaced them.</div> <div> Cierva died in a Douglas DC-2 crash on December 19, 1936, at Croydon,England.</div> <bR> <div> <IMG SRC="11a7c6ec0.jpg" border=0 width="454" height="236" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> A replica Cerva C.30A Autogiro  that was built in Argentina and registered as LV-FBL now lives at Cuetro Ventos.</div> <bR> <div>    ____________________________________________________________________________________________</div> <bR> <div> <IMG SRC="11ad58aa0.jpg" border=0 width="600" height="426" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> Agusta A.109 Power.</div> <bR> <div>   _____________________________________________________________________________________________</div> <bR> <div> MRH 90</div> <div> <IMG SRC="11e758a50.jpg" border=0 width="600" height="421" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div>     _____________________________________________________________________________________________</div> <bR> <bR> <bR> <bR> <bR> </td> </tr></table></body>
