 Vickers Viscount - Wikipedia, the free encyclopedia
There was some work on replacing the Darts with the Armstrong Siddeley Mamba, but this was dropped by the time the prototypes were reaching completion.
The prototype Model 630 flew on July 16, 1948, and the second prototype was built as a test-bed with two Rolls-Royce Tay turbojets in place of the four Darts.
Originally to be named Viceroy, the name had to be changed after the partition of India in 1947.

 Fairey Gannet -- Facts, Info, and Encyclopedia article
A Double Mamba (also commonly called the "Twin Mamba") was selected, driving two counter-rotating (A mechanical device that rotates to push against air or water) propellor s through a common (The shell (metal casing) in which a train of gears is sealed) gearbox.
The Double Mamba engine could be cruised with one of the engines stopped, to conserve fuel and extend endurance.
At least one Gannet accident was attributed to the vibration from the engine causing fatigue cracking of the tail, to the extent that the tail separated inflight.

This was passed for developement to Bristol Siddeley and, later, Rolls Royce.
The names of these models echoed the names of aircraft produced by the Hawker Siddeley Group (the name adopted by the company in 1935) during the war.
The first car produced from this union was a fairly massive machine, a 5-litre 30 hp ; a smaller 18 appeared in 1922 and a 2-litre 14hp was introduced in 1923.

 The Breguet Alize & Fairey Gannet
The Br.960-1 was powered by an Armstrong Siddeley Mamba A.S.Ma.1 turboprop engine with 730 kW (980 SHP), mounted in the nose and driving a four-bladed propeller for cruise flight, and a Rolls-Royce Nene 101 centrifugal-flow turbojet with 21.6 kN (2,200 kgp / 4,850 lbf) thrust, fitted in the tail for takeoff and combat power.
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 vertical tailplane was raised in height to aerodynamically compensate for the radome.

When construction began official favor had switched to the Armstrong Siddeley Mamba but the Dart was back in vogue by the time the first prototype took to the air on July 16, 1948 as the Type 630.
In 1944, when the committee first approached Vickers Armstrong about the possibility of exploiting the new turboprop technology in an airliner for European services the company was already considering how to replace its Viking.
For a type that was to prove so successful the early days saw the Viscount in the shadow of the Ambassador and it was only when the Dart R.Da.3 became available, offering 40 per cent more power, that the project took off as the stretched 40-passenger Type 700, first flying on August 3, 1950.

 Probert Encyclopaedia: Aviation (Fa-Fk)
The Fairey Gannet was a mid inverted-gull wing monoplane powered by an Armstrong Siddeley Double Mamba 101 turboprop providing a top speed of 481 kmh and a range of 1510 km.
The Fiat G.91 R-3 was powered by a Bristol Siddeley Orpheus 801/02 turbojet providing a top speed of 1090 kmh and a range of 1850 km.
The Fairey Gannet was a British carrier-borne three-seater anti-submarine search and strike and reconnaissance aircraft in service with the Fleet Air Arm from 1953 to 1960 (the assault version) and 1978 (the reconnaissance version).

 Flight 14.11.1952
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.

 Aero Engine Information
The Mamba has virtually a straight-through air flow system, its diameter (less than 30ins measured over the cowling) is remarkably small and the frontal area only about 30% of that of an equivalent piston engine.
The Mamba engine was used on the Avro Athena and Boulton Paul Balliol prototype.
One of the main features of the engine is a pre-heating of the fuel/air mixture by directing the fuel upstream against the primary air flow, this can readily be seen on the engine.

The Mamba was developed into the form of the Armstrong-Siddeley Double Mamba on the Fairey Gannet anti-submarine aircraft developed for the Royal Air Force.
The '''Mamba''' was Armstrong-Siddeley 's gas turbine turboprop engine design of around 1,500hp.
In 1949, a Dakota testbed aircraft was converted by Armstrong-Siddeley to take two Mambas.

 The RAF's Cancelled Aircraft
The winning entry was the Hawker Siddeley HS.681, a C130 size aircraft powered by four Bristol Siddeley "Pegasus" vectored thrust engines as used on the Harrier.
Engines would be provided by Bristol Siddeley who had uprated their "Olympus 22R" to the required performance.
A great deal of time and money was put into the project but the Board of Hawker Siddeley decided to discontinue work on the Helicrane (and helicopters in general) leaving the rotary-wing field open for Westland Helicopters.

 Warbird Alley: Fairey Gannet
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.
Ten years of design and development led to the adoption of the Fairey Gannet, a highly successful three-man aircraft built around a most unusual engine.

 Fairey Gannet
Fairey Aviation selected the Armstrong Siddeley Mamba turboprop and suggested coupling two of these engines together, driving a co-axial propeller.
Each half of the power plant could be separately controlled, giving the pilot the option of shutting down one half and feathering the propeller to extend cruise range and lengthen search time.
The Fairey Gannet, a familiar sight in many parts of the world during the late 1950s, originated in an Admiralty requirement, issued in 1945, for a new anti-submarine aircraft.

The engines helped, but the unpressurized aircraft couldn't be flown at an altitude that would use the engines to their best advantage, and the project was quickly dropped.

 Rolls-Royce: History
The Coventry Branch is guardian to the heritage of the Armstrong Siddeley company, its predecessors the Deasy Motor Car Manufacturing Company, Siddeley-Deasy at Parkside in Coventry, the subsequent activities of Bristol Siddeley and ultimately Rolls-Royce, both at Parkside and at Ansty.
The Sphinx magazine, covering the work of the Branch and the history of Armstrong Siddeley is published twice a year for members.
It constitutes the finest record of Armstrong Siddeley achievement anywhere, encompassing motor cars, aero engines, rocket engines and engines for industrial and marine applications.
