	Fairey Gannet - Wikipedia, the free encyclopedia
		A Double Mamba (also commonly called the "Twin Mamba") was selected, driving two counter-rotating propellors through a common gearbox.
		The Double Mamba engine could be cruised with one of the engines stopped, to conserve fuel and extend endurance.
		The pilot sits over the gas turbine engine atop the fuselage and behind the double, co-axial, contra-rotating propellors; the one (or two) crew sit in additional cockpit stations behind the pilot.

	Armstrong-Siddeley Double Mamba - Wikipedia, the free encyclopedia
		The Double Mamba (also known as the Twin Mamba) was a development of the Armstrong-Siddeley Mamba with two Mambas driving through a combining gearbox.
		The Double Mamba was an Armstrong-Siddeley gas turbine turboprop engine design of around 3,000–4,000 hp (2,500–3,000 kW).
		The Double Mamba engine was also proposed for the Westland Westminster, a 30-seat helicopter that was later prototyped with another engine.

	The Breguet Alize & Fairey Gannet
		The Double Mamba was what would now be called a "twin pac" engine, with two turboprop engines driving a common gearbox, which in turn drove a contrarotating propeller system with four blades per propeller.
		The Double Mamba was one of the first such schemes to prove workable, though now double turboshafts are fairly common powerplants for helicopters.
		The vertical tailplane was raised in height to aerodynamically compensate for the radome.

		The Double Mamba engine series was the result of coupling a pair of single Mamba's which drove through a common gearbox.
		It was developed by Armstrong Siddeley, Bristol Siddeley and latterly Rolls Royce.
		The Adder turbojet was created by removing the reduction gearbox from the Mamba turboprop engine.

		However, it was decided to concentrate work on the Double Mamba- two of the engines mounted together and driving contrarotating propellers.
		As with most turboprops, the Mamba was much lighter than the Pratt & Whitney Twin Wasp radial that it was replacing (the radial weight about 1450 pounds compared to the 1000 pounds of the turboprop) so the engines had to be mounted in greatly extended nacelles.
		The sleek nacelles housing the Mambas were quite attractive on the Dakota and flight tests proved that the engine was fairly reliable.

	Alenia G-222VS
		The Armstrong Siddeley Double Mamba ASMD1 engine provided 2950ehp and was basically two Mamba engines mounted side-by-side, linked to a common gearbox and driving contra-rotating, co-axial propellers - however, despite all this, the aircraft was underpowered.
		To cope with the extra weight of all the equipment, a new version of the Armstrong Siddeley Double Mamba engine was introduced, the 112 engine which provided 3875ehp and produced what can only be described as a distinctive noise.
		The pilots cockpit remained virtually identical to the AS version, but in the AEW version the two radar operators were located in a cramped cabin buried in the fuselage and accessed by way of a door above the wing trailing edge.

	Carrier Aviation
		The Gannet was to have been replaced by the Hawker Siddeley (formerly Blackburn Aircraft, Brough) P139B during the early 1970’s.
		A COD or carrier-on-deck version of this aircraft was also planned, for the carriage of urgent stores from shore base to the carrier group.
		The prototype AEW Gannet flew in August 1958 and a total 44 AEW Gannets were built, again serving in the front line with 849 NAS, from February 1960.

	Flight 14.11.1952-12/11/2002-Flight International
		That the Armstrong Siddeley Double Mamba turboprop is able to run on ship's diesel fuel has long been public knowledge; what is news is that a Fairey Gannet carrier-borne anti-submarine prototype has actually been airborne with this fuel in use.
		A Dakota of the R.A.A.F., carrying four crew-members and two scientists of the Commonwealth Industrial Research Organization, was reported missing on October 27th after flying 50 miles out to sea from Sydney to observe a rainstorm; the scientists, R.S. Styles and F.W. Campbell, were engaged on rain-making research.
		The fuel concerned is 47 cetane, used in the Royal Navy for all diesel-powered generating plant and other auxiliary engines in aircraft carriers.

	Warbird Alley: Fairey Gannet
		The Armstrong-Siddeley Double Mamba coupled turboprop engine boasted two independent power sections driving separate propellers.
		The problems of fixed-wing aircraft on small decks led to the Gannet’s replacement by Wessex helicopters in the 1970’s but a number have survived in museums, including two which are airworthy in the USA.
		After both sections were used in the crucial take-off phase, one could be shut down to extend range and patrol time.

		Some DC-3s were upgraded to use Rolls-Royce Dart or Armstrong Siddeley Mamba turbines.
		The most popular was the Pratt and Whitney R-1830 Double Wasp radial, but Wright R-1820 Cyclone, and Pratt and Whitney R-2000 radials saw use.
		The Basler BT-67 is a derivative type of the DC-3.

		The earliest turboprop conversion was done by Armstrong Siddeley in 1949 to flight-test Mamba turboprop engines, though the aircraft was eventually refitted with Twin Wasps and sold off.
		They lacked the double doors and reinforced floor, and were fitted with metal seats for 28 paratroopers and an attachment point for a combat glider tow rope.
		The most visible change was fit of a double cargo door into the rear left side of the fuselage, with a passenger door nested inside the right half of the cargo door.

		Однако создание этого двигателя задерживалось, и Y.A.5 был перепроектирован в самолет Y.B.1 под спаренный турбовинтовой двигатель Armstrong Siddeley Double Mamba.
		Двигатель Double Mamba имел ряд преимуществ перед обычными силовыми установками: каждая его половина имела независимое управление, что обеспечивало возможность полета самолета на одной половине при неработающей второй и увеличивало дальность полета.
		Усовершенствование двигателя Double Mamba породило более мощный вариант Mk 101 с эффективной мощностью на валу 3035 л.с., что вместе с небольшими изменениями в оборудовании привело к появлению самолета Gannet AS.Mk 4, который вытеснил из производства модель Gannet AS.Mk 1.

		As well as their own designs Armstrong Whitworth built aircraft from other companies in the Hawker Siddeley Group including the Hawker Sea Hawk and Hunter, and the Gloster Meteor.
		These include a collection of aero engines (such as the Sapphire, Avon, Stentor, Double Mamba), missiles (Red Dean, Firestreak) and parts from historic aircraft such as the Bristol T.188 stainless steel research aircraft.
		A number of the museum's aircraft were operated in the local area such as the de Havilland Vampire F.1 of 605 Squadron (the only Mk.1 Vampire left in the UK and one of only two in the world).
