The Bristol Aeroplane Company (formerly British and Colonial Aeroplane Company) was a major British aviation company. In 1956 its major operations were split into '''Bristol Aircraft''' and '''Bristol Aero Engines'''. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the ''' British Aircraft Corporation ''' (BAC). At the same time, Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley . BAC went on to become a founding component of the nationalised British Aerospace , now BAE Systems . Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. The BAC / Bristol works were located in Filton , about 4 miles north of Bristol city centre. BAE Systems still operate from Filton. HISTORY .]] The British and Colonial Aeroplane Company, Limited was founded in 1910 by Sir George White - the owner of Bristol Tramways - to manufacture aircraft at Filton in Bristol. Unlike most aviation companies at the time, which were started by enthusiasts with little financial backing or business organization, British and Colonial was from its outset well funded and run by experienced businessmen. The Company's initial venture was a licensed and improved version of the Voisin brothers' Zodiac 'Boxkite' biplane, which was shown at the Aero Show at Olympia in March 1910 . Unfortunately the Zodiac was extremely underpowered, and never flew. Production of Bristol's first successful design, the Bristol Boxkite , started in a former tramway shed at Filton in June 1910. A month later the Company also formed a flying school, with premises at Brooklands , near London, and Larkhill on Salisbury Plain . This flying school was regarded as one the best in the world, between 1910 and 1914. By 1914, 308 of the 664 Royal Aero Club certificates issued had been gained at the Company's schools. First World War The Company expanded rapidly during this time, reaching a payroll of 200 by the outbreak of the First World War . The chief designer (styled ''chef technique'') from January 1912 until October 1914 was the Romanian engineer Henri Coandă . Coandă was succeeded by Frank Barnwell , who was to become one of the world's foremost aeronautical engineers. One of Barnwell's first designs, the Bristol Scout , was one of the very first fighter aircraft to enter British service. Later in the war came the mass-produced two-seat Bristol Fighter , which was one of the backbones of the Royal Flying Corps (RFC), later the Royal Air Force (RAF). Inter-war years By the end of the war, the Company employed over 3000, at its production works at Filton and Brislington . Its products had always been referred to by the name 'Bristol' and this was formalized in 1920, when British and Colonial was Liquidated and its assets became the Bristol Aeroplane Company, Limited. At this time the Company bought the failing Cosmos Engineering Company , also of Bristol, to form the nucleus of its new aero-engine operations; the '''Bristol Engine Company'''. A major product during the interwar years was the Bristol Bulldog fighter, which formed the mainstay of RAF fighters between 1918 and 1935. During this time Bristol was noted for its policy of 'all-steel' airframes, preferring steel to the light alloys generally used in aircraft construction. Bristol airframes were built up from high-tensile strip steel rolled into section, and were powered exclusively by Bristol's own engines. On 15 June 1935 the Bristol Aeroplane Company became a Public Limited Liability Company . By this time the Company had a payroll of 4200, mostly in the engine factory, and was well positioned to take advantage of the huge re-armament ordered by the British Government in May of that year. Bristol's most important contribution to the expansion of the RAF at this time was the Blenheim light bomber. In August 1938 Frank Barnwell was killed in a light plane crash, and was succeeded as Chief Designer by Leslie Frise . By the time war broke out in 1939 the Bristol works at Filton were the largest single aircraft manufacturing unit in the world, with a floor area of nearly 25 Hectare s (2,691,000 square feet). Second World War During the Second World War Bristol's most important aircraft was the Beaufighter heavy two-seat multirole aircraft; a long-range fighter, Night Fighter , Ground Attack Aircraft and Torpedo Bomber . It was used extensively by the RAF and Commonwealth air forces, and by the USAAF . The Beaufighter was derived from the earlier Beaufort torpedo bomber, itself a derivative of the Blenheim. In 1940 a Shadow Factory had been set up at Weston-super-Mare for the production of Beaufighters. The companies war time headquarters was in the Royal West Of England Academy . Post-war When the war ended Bristol set up a separate helicopter division in the Weston-super-Mare factory, under helicopter pioneer Raoul Hafner . The Helicopter Division of Bristol was taken over by Westland in 1960 . Other post-war projects included Bristol Cars , which used pre-war BMW designs as the basis for a new car, the Bristol 400 . The engine developed from this project found its way into many successful motor cars manufactured by other companies, such as Cooper , Frazer Nash and AC , and in and powered Bristol's own Bristol 450 Sports Prototype to class victories in the 24 Hours Of Le Mans race. The car company became independent in 1960, around the same time as the consolidation the British aircraft industry, but is still based at the Filton site. Pre-fabricated buildings, marine craft and plastic and composite materials were also early post-war activities, but these were eventually sold off. Bristol was involved in the post war renaissance of British civilian aircraft as inspired by the Brabazon Committee report. In 1949, the Bristol Brabazon airliner prototype, at the time one of the largest aircraft in the world, first flew. The Brabazon airliner project was a step in the wrong direction and ultimately cancelled in 1953. At the same time the Bristol Britannia turboprop-powered airliner proved a huge success and it and the Bristol Freighter transport aircraft were produced in quantity during the 1950s. Bristol was also involved in Helicopter development with the Bristol Belvedere and Bristol Sycamore helicopters going into quantity production. Another post-war activity was Missile development, culminating in the production of the Bristol Bloodhound anti-aircraft missile. Bristol Aero Engines produced a range of Rocket Motor s and Ramjet s for missile propulsion. The guided weapons division eventually became part of Matra BAe Dynamics Alenia ( MBDA ). In the late 1950s the Company undertook supersonic transport (SST) project studies, which were later to contribute to Concorde . A research aircraft, the Bristol 188 , was constructed in the 1950s to test the feasibility of Stainless Steel as a material in a Mach 2.0 airframe. By the time the aircraft flew in 1962, the Company was already part of the British Aircraft Corporation. Merger into BAC In 1959 Bristol was forced by Government policy to merge with English Electric , Hunting Aircraft and Vickers-Armstrongs to form the British Aircraft Corporation (BAC). In 1977, BAC was nationalised, along with Scottish Aviation and Hawker Siddeley to form British Aerospace (BAe). BAe later became BAE Systems . BRISTOL ENGINE COMPANY The Bristol Engine Company was originally a separate entity, Cosmos Engineering , in turn formed from the pre-First World War automobile company, Brazil-Straker. In 1917 Cosmos was asked to investigate air-cooled Radial Engine s, producing what would become the Bristol Mercury , a 14 cylinder two-row (helical) radial, which they launched in 1918. This engine saw little use, but a smaller and simpler 9 cylinder version known as the Bristol Jupiter was clearly a winning design. With the post-war rapid contraction of military orders Cosmos Engineering went Bankrupt , and the Air Ministry let it be known that it would be a good idea if the Bristol Aeroplane Company purchased them. The Jupiter competed with the Armstrong Siddeley Jaguar through the 1920s, but Bristol put more effort into their design, and by 1929, the Jupiter was clearly superior. In the 1930s they developed a New Line Of Radials based on the Sleeve Valve principle, which would develop into some of the most powerful piston engines in the world, and could continue to be sold into the 1960s. In 1956 the division was renamed Bristol Aero Engines, and then merged with Armstrong Siddeley in 1958 to form ''' Bristol Siddeley ''' as a counterpart of the airframe-producing company mergers that formed BAC. In 1966 Bristol Siddeley was purchased by Rolls-Royce , leaving the latter as the only major aero-engine company in Britain. Rolls-Royce continues to produce aircraft engines as Rolls-Royce Plc . A number of Bristol Siddeley engines of Bristol heritage continued to be developed by Rolls-Royce; notably the Olympus turbojet and the Pegasus . The classical names favoured by Bristol indicated their heritage in a Rolls-Royce lineup named after British Rivers PRODUCTS Aircraft pre-World War I
