Boulton Paul Aircraft Ltd was a British aircraft manufacturer that was incorporated in 1934, although its origins in aircraft manufacturing began earlier in 1914 and lasted until 1961. The company mainly built and modified aircraft under contract to other manufacturers, but had a few notable designs of its own, such as the Defiant fighter and the Balliol trainer.
The company's origins date back to an ironmonger's shop founded in 1797 in Norwich. By the early 1900s, Boulton & Paul Ltd was a successful general manufacturing firm with a construction engineering division. It began building aircraft under contract during the First World War before moving into designing and building its own aircraft.
The aircraft building business was sold off - at a low point in the aviation market - from the main construction business in 1934 and then moved to Wolverhampton under its new name Boulton Paul Aircraft Ltd in 1936 to take advantage of skilled local workforce and local government incentives.
By 1961 Boulton Paul Aircraft was a manufacturer of aircraft equipment rather than aircraft, it merged with the Dowty Group.
Boulton & Paul started its construction engineering division in 1905. [1] [ page needed ]
In 1915, Boulton & Paul began to construct aircraft under contract, including 550 of the Royal Aircraft Factory FE.2b. During the war the company built more Sopwith Camels than any other manufacturer. Success as an aircraft builder led the company to form a design department but none of its resulting aircraft made a significant impact while the war lasted. Boulton Paul's chief aircraft designer was John Dudley North (1893–1968), who joined the company from Austin Motor Company Aircraft Department.
After World War I, Boulton & Paul made their mark with the introduction of powered and enclosed defensive machine gun turrets for bombers. Their Sidestrand twin-engined biplane bomber, which could fly at 140 mph (230 km/h), had an exposed nose turret which was clearly inadequate. The subsequent Overstrand bomber featured the world's first enclosed, power-operated turret, mounting a single Lewis gun and propelled by compressed air. The company licensed a French design of an electro-hydraulic four-gun turret which became a major feature of their future production. In addition to fitting turrets to bombers, Boulton Paul was to install them in fighters.
During this period Boulton & Paul continued to operate outside the aircraft industry as well. They manufactured equipment such as machine tools and stationary engines. The latter were also available coupled to a dynamo for powering electric lighting circuits, and were sold under the Electolite brand name.
In 1934, Boulton & Paul sold their "Aircraft Department" which became Boulton Paul Aircraft Ltd. Over the next couple of years a new factory site was built up in Wolverhampton. [2] [ page needed ] This gave access to a large skilled workforce on top of the 600 or so employees that left Norwich for Wolverhampton. Even so, Boulton Paul would later set up a training centre in Scotland to bring in extra workers. The first "turret" fighter to be built was some of the Hawker Demon. This was followed by Boulton Paul's most famous aircraft, the Defiant, which was a revolutionary but flawed concept specified by the Air Ministry – a "fast" fighter with no fixed forward armament but a powerful four-gun dorsal turret at a time when most interceptors had only two machine guns. Turret fighters were expected to be able to work together to engage undefended enemy bombers from any aspect, concentrating their fire. In practice, once Germany defeated France in 1940 their high performance but short range fighters were able to escort bombers. The same concept was used for the Defiant's naval equivalent, the Blackburn Roc, which while a design by Blackburn, the detail design was done in BP's drawing office and the aircraft was built wholly by Boulton Paul.
Boulton Paul also built the Fairey Barracuda and did conversions of the Vickers Wellington. The only post-war design was the Balliol advanced trainer, of which 229 were built, including 30 as the Sea Balliol deck-landing trainer.
In the jet age, Boulton Paul worked on the English Electric Canberra and de Havilland Vampire. It designed and built a couple of delta-wing jet-engined aircraft for research work and continued to tender designs for official requirements. In 1961 the company was acquired by Dowty Group and was renamed Dowty Boulton Paul Ltd and then Dowty Aerospace.
Following the acquisition of Dowty Aerospace by TI Group in 1992, and the subsequent merger of Smiths Industries and the TI group in 2000, to form Smiths Group, the Wolverhampton factory site was sold again in May 2007 to GE Aviation Systems. Yet again in August 2009 the factory was sold to Moog Inc. but was to move to new premises at the nearby I54 business park. The factory also had an on-site Boulton Paul Museum dedicated to Boulton Paul aircraft and the traditional methods used to manufacture aircraft. The important collection was scheduled to move to Royal Air Force Museum Cosford in Spring 2013. Short video of the move captured April 28,2013 [3] .[ needs update ]

Boulton Paul was one of the two main innovators of gun turret designs for British aircraft [a] , along with Nash & Thompson; they supplied large numbers of installations for British aircraft. Boulton Paul's designs were largely based on originals licensed from the French company Société d'Applications des Machines Motrices (SAMM), while Nash & Thompson designs originated from the firm's co-founder, Archibald Frazer-Nash (and were known by FN designations)[ citation needed ] Boulton Paul's turrets were electro-hydraulic in operation; electric motors located in the turret drove hydraulic pumps that powered hydraulic motors and rams. This was more effective than electric motors alone, and did not require hydraulic power developed by pumps on the aircraft's engines system utilized by the Nash & Thompson design. Production was transferred to Joseph Lucas Ltd.

The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the 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) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley.

Handley Page Limited was a British aerospace manufacturer. Founded by Frederick Handley Page in 1909, it was the United Kingdom's first publicly traded aircraft manufacturing company. It went into voluntary liquidation and ceased to exist in 1970. The company, based at Radlett Aerodrome in Hertfordshire, was noted for its pioneering role in aviation history and for producing heavy bombers and large airliners.
Schräge Musik was a common name for the fitting of an upward-firing autocannon or machine gun, to an interceptor aircraft, such as a night fighter. The term was introduced by the German Luftwaffe during World War II. "Schräge Musik" was previously a German colloquialism, meaning music that featured an unusual tuning and/or time signature. The standard usage of the adjective schräg is often translated as "slanting" or "oblique", but its slang usage is often translated as "weird" or "strange".
The Fairey Aviation Company Limited was a British aircraft manufacturer of the first half of the 20th century based in Hayes in Middlesex and Heaton Chapel and RAF Ringway in Cheshire that designed important military aircraft, including the Fairey III family, the Swordfish, Firefly, and Gannet. It had a strong presence in the supply of naval aircraft, and also built bombers for the RAF.
The Blackburn Roc was a naval fighter aircraft designed and produced by the British aviation company Blackburn Aircraft. It took its name from the mythical bird of the tales of the Arabian Nights, the Roc. It was operated by the Fleet Air Arm (FAA) and was active during the Second World War.
The Boulton Paul Defiant is a British interceptor aircraft that served with the Royal Air Force (RAF) during World War II. The Defiant was designed and built by Boulton Paul Aircraft as a "turret fighter" to meet the RAF requirement for day and night fighters that could concentrate their firepower on enemy bombers which were not expected to have fighter escorts due to the distance from Germany to the United Kingdom. The Defiant had all its armament in a dorsal turret offering the ability to fire in most directions. The same principle was used in the Royal Navy's Blackburn Roc which was also built by Boulton Paul.
