The original name of Skyworks Aeronautics Corp. was Groen Brothers Aviation. It started out by incorporating helicopter design components into autogyro design. They added helicopter-style collective pitch control which allowed their aircraft to achieve vertical takeoff and landing and to stabilize flight at high and low speeds.
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 ...
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.
A Bell UH-1 Iroquois helicopter. A helicopter is a powered rotorcraft with rotors driven by the engine(s) throughout the flight, allowing it to take off and land vertically, hover, and fly forward, backward, or laterally. Helicopters have several different configurations of one or more main rotors.
A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau .
The aircraft has an empty weight of 262 kg (578 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 188 kg (414 lb). [1] [2] Even though the manufacturer is an Austrian company the aircraft is built in Slovenia. The G 4-2 R was noted by Bayerl et al. in 2011 for its unusual new aircraft two-year warranty. [1]
The Bell Huey family of helicopters includes a wide range of civil and military aircraft produced since 1956 by Bell Helicopter.This H-1 family of aircraft includes the utility UH-1 Iroquois and the derivative AH-1 Cobra attack helicopter series and ranges from the XH-40 prototype, first flown in October 1956, to the 21st-century UH-1Y Venom and AH-1Z Viper.
The Fairey Jet Gyrodyne is a British experimental compound gyroplane built by the Fairey Aviation Company that incorporated helicopter, gyrodyne and autogyro characteristics. . The Jet Gyrodyne was the subject of a Ministry of Supply (MoS) research contract to gather data for the follow-up design, the Rotody
