Blind Landing Experimental Unit
The Blind Landing Experimental Unit, abbreviated BLEU, was a unit of the British government tasked with creating an early autolanding system for military and civilian aircraft from the late 1940s until the mid-1960s. Background Pilots in the early days of aviation relied on dead reckoning to find out where they were flying, which proved difficult or impossible at night or in bad weather. A 1925 United States Post Office study found that 76% of its forced landings were due to weather, which highlighted the early need for a system to facilitate blind landings. Early suggestions at addressing the problem ranged from using primitive radio signals to placing emergency landing strips periodically near major highways. Experiences from the Second World War called more attention to the problem. Bombers based in Britain would sometimes return to their home bases in the early morning hours to find all of their landing sites completely fogged in, which resulted in the senseless loss of airf ...

Ambrose Channel Pilot Cable
The Ambrose Channel pilot cable, also called the Ambrose Channel leader cable, was a cable laid in Ambrose Channel at the entrance to the Port of New York and New Jersey that provided an audio tone for guiding ships in and out of port at times of low visibility. The cable was laid during 1919 and 1920; it had been removed from the channel and replaced by wireless technology by the end of the 1920s. Background Ambrose Channel is the only shipping channel into and out of the Port of New York and New Jersey, an important commercial port. Delays posed a major problem for shipping en route to New York City, and bad weather could close the channel for days. Ships were forced to wait at the harbor's entrance for conditions to clear. These delays cost shipping companies substantial amounts of money, with each ship costing between $500 and $4000 per hour it was stopped (roughly $5,700 to $46,000 in 2013 dollars). Description and operation The Ambrose leader cable was an armored cable w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Varsity
The Vickers Varsity is a retired British twin-engined crew trainer operated by the Royal Air Force from 1951 to 1976. Design and development The Varsity was developed by Vickers and based on the Viking and Valetta to meet Air Ministry Specification T.13/48 for a twin-engined training aircraft to replace the Wellington T10 and the Valetta T3 and T4. The main differences were the wider-span wings, longer fuselage and tricycle undercarriage. There was also a ventral pannier to allow a trainee bomb aimer to lie in a prone position and a bomb bay with a capacity for 24 x 25lb smoke & flash bombs. The first prototype Type 668 Varsity VX828 was first flown by J 'Mutt' Summers and G R 'Jock' Bryce from Wisley on 17 July 1949. A civil version the VC.3 was planned but with the success of the VC.2 Viscount the idea was abandoned. Operational history The Varsity was introduced to replace the Wellington T10 trainer. Following deliveries to trials units the first production aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V Bomber
The "V bombers" were the Royal Air Force (RAF) aircraft during the 1950s and 1960s that comprised the United Kingdom's strategic nuclear strike force known officially as the V force or Bomber Command Main Force. The three models of strategic bomber, known collectively as the ''V class'', were the Vickers Valiant, which first flew in 1951 and entered service in 1955; the Avro Vulcan, which first flew in 1952 and entered service in 1956; and the Handley Page Victor, which first flew in 1952 and entered service in 1957. The V Bomber force reached its peak in June 1964 with 50 Valiants, 70 Vulcans and 39 Victors in service. When it became clear that the Soviet Union's surface-to-air missiles like the S-75 Dvina could bring down high-flying aircraft, the V bomber force changed to low-level attack methods. Additionally the Blue Steel missile profile was changed to one of low level penetration and release. This reduced its range significantly. It was then planned to move to the muc ...

RAF Fighter Command
RAF Fighter Command was one of the commands of the Royal Air Force. It was formed in 1936 to allow more specialised control of fighter aircraft. It served throughout the Second World War. It earned near-immortal fame during the Battle of Britain in 1940, when the Few held off the Luftwaffe attack on Britain. The Command continued until 17 November 1943, when it was disbanded and the RAF fighter force was split into two categories; defence and attack. The defensive force became Air Defence of Great Britain (ADGB) and the offensive force became the RAF Second Tactical Air Force. Air Defence of Great Britain was renamed back to Fighter Command in October 1944 and continued to provide defensive patrols around Great Britain. It was disbanded for the second time in 1968, when it was subsumed into the new Strike Command. Origins On 20 May 1926, the forerunner of Fighter Command was established as a group within Inland Area. On 1 June 1926, Fighting Area was transferred to the ...

English Electric Canberra
The English Electric Canberra is a British first-generation, jet-powered medium bomber. It was developed by English Electric during the mid- to late 1940s in response to a 1944 Air Ministry requirement for a successor to the wartime de Havilland Mosquito fast bomber. Among the performance requirements for the type was an outstanding high-altitude bombing capability and high speed. These were partly accomplished by making use of newly developed jet-propulsion technology. When the Canberra was introduced to service with the Royal Air Force (RAF), the type's first operator, in May 1951, it became the service's first jet-powered bomber. In February 1951, a Canberra set another world record when it became the first jet aircraft to make a nonstop transatlantic flight. Throughout most of the 1950s, the Canberra could fly at a higher altitude than any other aircraft in the world, and in 1957, a Canberra established a world altitude record of . Due to its ability to evade the early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloster Meteor
The Gloster Meteor was the first British jet fighter and the Allies of World War II, Allies' only jet aircraft to engage in combat operations during the Second World War. The Meteor's development was heavily reliant on its ground-breaking turbojet engines, pioneered by Frank Whittle and his company, Power Jets, Power Jets Ltd. Development of the aircraft began in 1940, although work on the engines had been under way since 1936. The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF. The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter. Gloster's 1946 civil Meteor F.4 demonstrator ''G-AIDC'' was the first Aircraft registration, civilian-registered jet aircraft in the world. Several major variants of the Meteor incorporated technological advances during the 1940s and 1950s. Thousands of Meteors were built to fly with the RAF and other air forces and remained in use for several decade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Valetta
The Vickers Valetta is a twin-engine military transport aircraft developed and produced by the British manufacturing company Vickers-Armstrongs Ltd. Developed from the Vickers VC.1 Viking compact civil airliner, it was an all-metal mid-wing monoplane with a tailwheel undercarriage. Development of the Valetta commenced during immediate postwar years as a consequence of Royal Air Force (RAF) interest in a military transport model of the Viking. Amongst the requirements stipulated for the aircraft was the need for it to rapidly alternate between various different roles, including that of a troop transport, air ambulance, freighter, glider tug and paratroop carrier. To accommodate these various roles, many of the aircraft's furnishings were designed to be rapidly removed and replaced by alternative configurations. Further design changes from the Viking included the adoption of more powerful Bristol Hercules 230 radial engines, a reinforced cabin floor and a strengthened undercarr ...

Armstrong Whitworth Albemarle
The Armstrong Whitworth A.W.41 Albemarle was a twin-engine transport aircraft developed by the British aircraft manufacturer Armstrong Whitworth and primarily produced by A.W. Hawksley Ltd, a subsidiary of the Gloster Aircraft Company. It was one of many aircraft which entered service with the Royal Air Force (RAF) during the Second World War. The Albemarle had been originally designed as a medium bomber to fulfil Specification B.9/38 for a aircraft that could be built of wood and metal without using any light alloys; however, military planners decided to deemphasise the bomber role in favour of aerial reconnaissance and transport missions, leading to the aircraft being extensively redesigned mid-development. Performing its maiden flight on 20 March 1940, its entry to service was delayed by the redesign effort, thus the first RAF squadron to operate the Albemarle, No. 295 at RAF Harwell, did not receive the type in quantity until January 1943. As superior bombers, such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Dove
The de Havilland DH.104 Dove is a British short-haul airliner developed and manufactured by de Havilland. The design, which was a monoplane successor to the pre-war Dragon Rapide biplane, came about from the Brabazon Committee report which, amongst other aircraft types, called for a British-designed short-haul feeder for airlines.Jackson 1987, p. 443. The Dove was a popular aircraft and is considered to be one of Britain's most successful postwar civil designs, in excess of 500 aircraft being manufactured between 1946 and 1967. Several military variants were operated, such as the ''Devon'' by the Royal Air Force and the ''Sea Devon'' by the Royal Navy, and the type also saw service with a number of overseas military forces. A longer four-engined development of the Dove, intended for use in the less developed areas of the world, was the Heron. A considerably re-designed three-engined variant of the Dove was built in Australia as the de Havilland Australia DHA-3 Drover. Devel ...

Vickers VC
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.
