The various types of such rotor wings may be classified according to the axis of the rotor. Types include: [1] [2] Vertical-axis. Conventional rotary wings as used by modern rotorcraft. Spanwise horizontal-axis. Wing rotor: an airfoil-section horizontal-axis rotor which creates the primary lift. Magnus rotor: a rotor which creates lift via the ...
The Ka-22 was in essence a fixed-wing aircraft with rotors fitted above the wing tips. An engine was mounted on each wing tip, with drive to both a four-bladed tractor propeller and a four-bladed main rotor. The original prototype was powered by 5,900shp Kuznetsov TV-2VK engines, although these were later replaced by the 5,500shp Soloviev D-25VK.
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 ...
An early American proposal was the conversion of the Lockheed F-104 Starfighter with a triangular rotor wing. The idea was later revisited by Hughes. [4] The Sikorsky S-72 research aircraft underwent extensive flight testing. In 1986 the Sikorsky S-72 Rotor Systems Research Aircraft (RSRA) was fitted with a four-bladed stopped rotor, known as ...
A quad rotor or quadrotor comprises four rotors in an "X" configuration. Rotors to the left and right are in a transverse configuration while those in the front and to the rear are in a tandem configuration. An advantage of quad rotors on small aircraft such as drones is the opportunity for mechanical simplicity.

The QTR is a larger, four rotor version of the V-22 with two tandem wings sets of fixed wings and four tilting rotors. In January 2013, the FAA defined US tiltrotor noise rules to comply with ICAO rules. A noise certification will cost $588,000, same as for a large helicopter. [15] [16]
Carter Aviation Technologies (also known as CarterCopters) is a privately held [2] aviation research and development company based in Wichita Falls, Texas, United States. The main focus of the company is developing new technology and then licensing it to other manufacturers for use on production aircraft. [ 3 ]
