The Cierva C.1 was an experimental autogyro built by Juan de la Cierva in Spain in 1920, the forerunner of his successful series of autogyros. The C.1 was created by taking the fuselage from a Deperdussin fixed-wing aircraft and mounting two rotors shaft above it.[1] This shaft carried two coaxial contra-rotating rotors, and atop it a fin for increased lateral stability. When tested, the C.1 refused to take off, which Cierva attributed to interference between the two sets of rotors leading to each set autorotating at a different speed. He considered the possibility of mechanically linking the rotors, but dismissed the idea on the grounds of weight and complexity, and his subsequent efforts would all feature single main rotors. Despite its failure to fly, the C.1 demonstrated the principle of autorotation in a full-sized aircraft for the first time, as it was taxied around the ground. {{aerospecs|ref= |met or eng?= |crew= |capacity= |length m= |length ft= |length in= |span m= |span ft= |span in= |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm= |wing area sqft= |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb= |lift kg= |lift lb= |eng1 number= |eng1 type= |eng1 kw= |eng1 hp= |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh= |max speed mph= |max speed mach= |cruise speed kmh= |cruise speed mph= |range km= |range miles= |endurance h= |endurance min= |ceiling m= |ceiling ft= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }} References{{commons category|Cierva aircraft}}1. ^[https://archive.is/20130102214923/http://www.cervantesvirtual.com/servlet/SirveObras/80248842108804940700080/index.htm text about La cierva (with C.1 photo).
