The Rise and Fall of Blackburn Buccaneer

Video Description

The Blackburn Buccaneer is a British carrier-capable attack aircraft designed in the 1950s for the Royal Navy. Designed and initially produced by Blackburn Aircraft at Brough, it was later officially known as the Hawker Siddeley Buccaneer when Blackburn became a part of the Hawker Siddeley Group, but this name is rarely used. The Buccaneer was originally designed in response to the Soviet Union introducing the Sverdlov class of light cruisers. Instead of building a new class of its own cruisers, the Royal Navy decided that it could address the threat posed via low-level attack runs performed by Buccaneers, low enough to exploit the ship's radar horizon to minimise the opportunity for being fired upon. The Buccaneer could attack using nuclear weapons or conventional munitions. During its service life, it would be modified to carry anti-ship missiles, allowing it to attack vessels from a stand-off distance and thus improve its survivability against modern ship-based anti-aircraft weapons. The Buccaneer was a mid-wing, twin-engine aircraft. It had a crew of two in a tandem-seat arrangement with the observer seated higher and offset from the pilot to give a clear view forwards to enable him to assist in visual search. Its operational profile included cruising at altitude (for reduced fuel consumption) before descending, just outside the anticipated enemy radar detection range, to 100 feet for a 500-knot dash to and from the target. Targets might be ships at sea or large shore-based installations at long range from the launching aircraft carrier. To illustrate, in May 1966, an S.2 launched from HMS Victorious in the Irish Sea, performed a low-level simulated nuclear weapon toss on the airfield at Gibraltar and returned to the ship, a 2,300-mile trip. The aircraft had an all-weather operational capability provided by the pilot's head-up display and Airstream Direction Detector, for example, and the observer's navigation systems and fire control radar. The Buccaneer was one of the largest aircraft to operate from British aircraft carriers and continued operating from them until the last conventional carrier was withdrawn in February 1979. During its service, the Buccaneer was the backbone of the Navy's ground strike operations, including nuclear strike. The fuselage of the Buccaneer was designed using the area rule technique, which had the effect of reducing aerodynamic drag while travelling at transonic speeds, and gave rise to the characteristic curvy "Coke bottle" shape of the fuselage. The majority of the airframe and fuselage was machined from solid castings to give the required strength to endure the stress of low-level operations. Considerable effort went into ensuring that metal fatigue would not be a limiting factor of the Buccaneer's operational life, even under the formidable conditions imposed by low-level flight. However, design changes for the Mark 2 Buccaneer, the addition of extended wingtips and the position of a new bolt hole, did cause fatigue problems leading to the loss of two aircraft. The wing design of the Buccaneer was a compromise between two requirements: a low-aspect ratio for good gust response, and high-aspect ratio to give good range performance. The small wing was suited to high-speed flight at low altitude; however, a small wing did not generate sufficient lift that was essential for carrier operations. Therefore, BLC was used upon both the wing and tailplane, having the effect of energising and smoothing the boundary layer airflow, which significantly reduced airflow separation at the back of the wing, and therefore decreased stall speed and increased effectiveness of trailing edge control surfaces, including flaps and ailerons. To extend the Buccaneer's operating life during the 1980s, it was deemed necessary to replace the original new spar rings on those aircraft that were retained. #BlackburnBuccaneer #NavalAviation #MilitaryAircraft #ColdWarJets #BritishEngineering #RoyalNavy #CarrierAircraft #AviationHistory #JetFighter #AttackAircraft #AviationGeeks #HistoricAircraft #MilitaryAviation #ColdWarEra #HawkerSiddeley
