Design

The Gannet was built in response to the 1945 Admiralty requirement GR. The Imperial War Museum Duxford in Cambridgeshire, England, commonly referred to simply as 'Duxford', houses the Imperial War Museum 's The Admiralty was formerly the authority in the United Kingdom responsible for the command of the Royal Navy. 17/45, for which prototypes by Fairey - Type Q or Fairey 17( after the requirement), and Blackburn B-54 / B-88 were built. The Blackburn B-54 and B-88 were prototype carrier-borne Anti-submarine warfare aircraft of the immediate post World War II -era developed for

After considering and discounting the Rolls-Royce Tweed^[2] turboprop, Fairey selected an engine based on the Armstrong Siddeley Mamba; the Double Mamba (or "Twin Mamba"). WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The Double Mamba was basically two Mambas mounted side by side and coupled through a common gearbox to contra-rotating propellers. Contra-rotating propellers, also referred to as coaxial contra-rotating propellers, apply the maximum power of a single piston or Turboprop engine The ASMD. 1 engine (2,950hp) was used in the Gannet AS. 1; ASMD. 3 (3,145hp) in the AS. 4; and ASMD. 4 (3,875hp) in the AEW. 3 variant. The Double Mamba engine could be run with one half stopped to conserve fuel and extend endurance for cruise flight. The contra-rotating propellers meant that when only one half of the Mamba was running, there were, no asymmetry of thrust problems encountered ^[3]. The Mamba exhausts on each side of the fuselage, at the root of the wing trailing edge. The gas turbine engine can run on kerosene, "wide-cut" turbine fuel or diesel fuel, allowing the Admiralty to eliminate the dangerous high-octane petroleum spirit required by piston engines from carrier operation. Kerosene, sometimes spelled kerosine in scientific and industrial usage is a Combustible Hydrocarbon liquid Diesel or Diesel fuel (ˈdiːzəl in general is any Fuel used in Diesel engines The most common is a specific fractional distillate of petroleum Avgas is a high-octane Aviation fuel used for Aircraft and Racing cars Avgas is a Portmanteau for aviation gasoline ^[3].

The pilot is seated well forward - conferring a good view over the nose for carrier operations^[2] - and sits over the Double Mamba engine, directly behind the gearbox and propellers. The second crew member, an aerial observer, is seated under a separate canopy directly behind the pilot. Aerial Observer - Air Force Reconnaissance. An Aerial Observer is the functional position of gathering information visually from an airborne platform for use by military After the proptoype, a second observer was included, in his own cockpit over the wing trailing edge. This addition disturbed the airflow over the horizontal stabiliser, requiring small finlets on either side^[4]. A tailplane, also known as horizontal stabilizer, is a small lifting surface located behind the main lifting surfaces of a Fixed-wing aircraft The Gannet has a large internal weapons bay in the fuselage and a retractable radome under the rear fuselage. A radome (the word is a contraction of Radar and Dome) is a structural weatherproof enclosure that protects a Radar antenna

The Gannet's wing folds in two places to form a distinctive Z-shape on each side. The first fold is at about 1/3 of the wing length where the inboard anhedral (down-sweep) changes to the outboard dihedral (up-sweep) of the wing. Dihedral is the upward angle from horizontal of the wings or tailpane of a Fixed-wing aircraft or the wing of a Bird. Dihedral is the upward angle from horizontal of the wings or tailpane of a Fixed-wing aircraft or the wing of a Bird. The second wing fold is at about 2/3 of the wing length. The length of the nose wheel oleo strut causes the Gannet to have a distinctive nose-high attitude, a common characteristic of carrier aircraft.

Development and service

An Airborne Early Warning variant (AEW Mk. 3) was developed to replace the American-supplied, piston-engined Douglas Skyraider aircraft. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout This aircraft carried the American AN/APS-20F radar in a large, bulbous radome suspended beneath the fuselage, under the wing leading edge, requiring a major strutural redesign^[5]. The fin area was increased to counter increase in side area of the radome, and the undercarriage had to be extended to provide the necessary ground clearance, giving the AEM. 3 a more-or-less level stance on the ground. The two radar operators were located in a cabin in the fuselage, accessed by small hatches over the wing trailing edge. This variant first flew in August 1958, with trials carried out with HMS Centaur in November.

Airframe and Handling Issues

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 in flight.

There is no known case of the tailplane separating in flight in RN service. Fatigue cracking of the tailplane attachment frame occurred on a number of AS. 1 and T. 2 aircraft due to buffeting in the flaps-up stall. In the worst case, one tailplane attachment fitting broke away allowing the tailplane to move in roll several degrees; the aircraft landed safely. The attachment frames of all aircraft were extensively reinforced after this incident.

Markings

In FAA service, the Gannet generally wore the standard camouflage scheme of a Sky (duck-egg blue) underside and fuselage sides, with Extra Dark Sea Grey upper surfaces, the fuselage demarcation line running from the nose behind the propeller spinner in a straight line to then curve and join the line of the fin. Code numbers are typically painted on the side of the fuselage ahead of the wing; roundel and serial markings were behind the wing.
