A gyrodyne is a type of VTOL aircraft with a helicopter rotor-like system that is driven by its engine for takeoff and landing only, and includes one or more conventional propeller or jet engines to provide thrust during cruising flight.
The Jet Gyrodyne was a modification of the second prototype FB-1 Gyrodyne aircraft registered G-AJJP. The Jet Gyrodyne was built specifically to develop the pressure-jet rotor drive system and operational procedures used on the later Rotodyne. The Jet Gyrodyne utilised the fuselage, undercarriage and engine of the FB-1
The extensively modified second prototype, renamed Jet Gyrodyne, flew in January 1954. Though retaining the name "Gyrodyne", the Jet Gyrodyne was a compound gyroplane, and did not operate on the same principle as the original aircraft. It had a two-blade rotor manually controlled with cyclic and collective pitch mechanisms that acted directly ...

The engine drove a 12 m diameter main rotor and two auxiliary propellers mounted on outriggers attached to the fuselage. At take-off or when hovering, the auxiliary propellers worked in opposition to each other and served to cancel the torque of the main rotor, [ 1 ] a function handled by a single, variable-pitch tail rotor on contemporary ...
The next developmental version was the DSN-2/QH-50B that was powered by two Porsche YO-95-6 engines and also carried a single Mk 43. Serial production of the DASH began with the third version, the DSN-3/QH-50C, in which a 255 hp (190 kW) Boeing T50-4 turboshaft engine replaced the piston engine and the payload was increased to two Mark 44 ...
In March 1952, Kayaba Industry began the development of the Heliplane, a Gyrodyne, which combines the advantages of autogyro and helicopter.Kayaba took advantage of experience producing the Ka-Go Ka-1 and Ka-2 autogyros, intended for reconnaissance, artillery-spotting and anti-submarine use, developed during World War II.
The Fairey Rotodyne was a 1950s British compound gyroplane designed and built by Fairey Aviation and intended for commercial and military uses. [1] A development of the earlier Fairey Jet Gyrodyne, which had established a world helicopter speed record, the Rotodyne featured a tip-jet-powered rotor that burned a mixture of fuel and compressed air bled from two wing-mounted Napier Eland turboprops.
