The concept of the movable wing of an autogyro is reminiscent of a helicopter, but there is one fundamental difference: in a helicopter the rotor is driven by a motor, while the blades of an autogyro only rotate thanks to the relative speed of the air when the plane moves. In the words of aerospace engineer Jeff Lewis, who has researched the histor...
The inventor of this ingenuity was born in Murcia (Spain) 120 years ago, on September 21, 1895. The well-off position of his family, established in the world of politics and business, allowed him to study road engineering and to found, together with two friends, a company dedicated to the development of the nascent field of aviation. They were just...
His engineer career began to take off in 1920 in Madrid with the construction of the first autogyro, the Cierva C.1. Although the craft never got off the ground, it proved thatthe principle of the self-turning rotor was valid. The main design problem was an asymmetry in the lift that caused instability in the machine. The C.2 and C.3 also suffered ...
However, the prediction of De la Cierva never came to pass. Despite being a safe aircraft and easy to use, it never succeeded. According to the researcher Jeff Lewis, several factors contributed to its abandonment. The autogyro could not reach the speeds required in commercial aviation, and for slow flight there was another option: by then, several...
After the death of De la Cierva, his company continued to work on and manufacture autogyro models, but the preference of the British Royal Navy for helicopters caused the company to refocus on that new machine in which De la Cierva himself did not believe, considering it «too complex». Nowadays,the autogyro has been quite relegated to the ambit of ...
Juan de la Cierva. 1886-1936. Spanish aviator and aeronautical engineer who pioneered rotary flight. In 1918, after receiving his engineering degree, he built the first trimotor airplane in Spain. In 1923 he designed an aircraft called the autogyro that combined the capabilities of a conventional fixed wing aircraft and the rotary action of the ...

Juan de la Cierva y Codorníu was a Spanish aeronautical and civil engineer, and pilot who is famous for the invention of the autogyro, the precursor to the helicopter.
Juan de la Cierva was introduced to flying when the Wright brothers demonstrated their flying machine to the world in 1908. Intrigued by this new technology, Cierva decided to build his own airplane. His first attempt was to rebuild a Sommer biplane.
