De la Cierva
Today in Aviation :: June 09, 2013
Juan de la Cierva was the son of a wealthy Spaniard who, by age 17 in 1912, was already designing aircraft in Spain. He continued on in school and earned a degree in civil engineering, though his first love remained airplanes. By 1919, he had given up on fixed wing aircraft designs because of their tendency to stall, often with disastrous results. If the stall problem could be solved, he reasoned, many lives would be saved. Thus, he began experimenting with a radical concept that involved the principles of autorotation, whereby a spinning rotor would allow the aircraft to descend to the ground without any risk of stalling. If there was just a way to fly based on autorotation, he reasoned, the problem would be solved.
On June 9, 1922 -- today in aviation history -- after four years of experimentation and numerous challenges that he overcame through many crashes and struggles with the problems of stability, control and roll, his first autorotation-based aircraft made its first successful flight. De la Cierva had invented what he called the "Autogiro", which is more commonly known as the Autogyro in English.
