a rotary wing aircraft intermediate in type, hereinafter referred to as "gyrodyne", between a rotaplane (with the rotor free for autorotation and an upward total axial flow through the rotor disc), on the one hand, and a pure helicopter (with the rotor driven, and a downward total axial flow through the rotor disc), on the other hand, that is ...
Skyworks Aeronautics Corp., formerly Groen Brothers Aviation, Inc., Groen Aeronautics Corporation and Skyworks Global, is an American autogyro research and development company based in Chicago. The company was founded in 1986 by David Groen and his late brother Jay Groen in Salt Lake City, Utah.
An autogyro (sometimes called gyrocopter, gyroplane, or rotaplane) uses an unpowered rotor, driven by aerodynamic forces in a state of autorotation to develop lift, and an engine-powered propeller, similar to that of a fixed-wing aircraft, to provide thrust. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air ...

The Air & Space 18A is a gyroplane that was manufactured in the central United States between 1965 and 2000.. The Air & Space 18A is one of the last three gyroplanes issued a Standard Airworthiness Certificate (September 1961) by the United States Federal Aviation Administration (FAA).
De la Cierva's Autogiro is considered the predecessor of the modern helicopter. [3] [4] The term gyrocopter (derived from helicopter) was used by E. Burke Wilford who developed the Reiseler Kreiser feathering rotor equipped gyroplane in the first half of the twentieth century. Gyroplane was later adopted as a trademark by Bensen Aircraft.
Gyropter Papin et Rouilly Monocopter design from Alphonse Papin and Didier Rouilly's 1914 patent. A monocopter or gyropter is a rotorcraft that uses a single rotating blade. The concept is similar to the whirling helicopter seeds that fall from some trees.
