First Autogiro Flight

First Autogiro Flight

On June 9, 1923, an autogiro, a new kind of aircraft invented by the Spanish engineer Juan de la Cierva, made its first flight. An autogiro is an ungainly cross between a propeller-driven airplane and a helicopter, wherein the large overhead propeller associated with the latter is attached to a propeller frame more like that of the former. Unlike a helicopter, however, the overhead propeller is typically not attached to the aircraft's engine; it starts spinning due to the momentum of the forward propeller and thereby helps provide lift. The autogiro enjoyed a certain popularity in the 1930s because it could take off from very small landing strips and because it was useful for military reconnaissance. However, it was ultimately eclipsed by the helicopter, which had a superior design and better maneuverability, including the ability to hover in one fixed location.
