The Aircraft Manufacturing Company Limited (Airco) was an early British aircraft manufacturer. Established during 1912, it grew rapidly during the First World War, referring to itself as the largest aircraft company in the world by 1918.
Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961.
The Handley Page H.P.42 and H.P.45 were four-engine biplane airliners designed and manufactured by British aviation company Handley Page, based in Radlett, Hertfordshire. They held the distinction of being the largest airliners in regular use in the world on the type's introduction in 1931.
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed (RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit.
The de Havilland DH.50 was a 1920s British large single-engined biplane transport built by de Havilland at Stag Lane Aerodrome, Edgware, and licence-built in Australia, Belgium, and Czechoslovakia.
The Handley Page H.P.24 Hyderabad was a twin-engine biplane heavy bomber designed and produced by the British aircraft manufacturer Handley Page. It holds the distinction of being the last wooden heavy bomber to be operated by the Royal Air Force (RAF).
The de Havilland DH.18 was a single-engined British biplane transport aircraft of the 1920s built by de Havilland.
The de Havilland DH.34 was a single engined British biplane airliner built by the de Havilland Aircraft Company in the 1920s. 12 were built, with the DH.34 serving with Imperial Airways and its predecessors for several years.
The Bristol Ten-seater and Bristol Brandon were British single-engine biplane transport aircraft built by the Bristol Aeroplane Company in the early 1920s. Only three were built, two of which were used as civil transports and one of which served with the Royal Air Force.
The Bristol Boarhound was a British army cooperation and liaison aircraft of the 1920s. It was a two-seat biplane with wings of equal span and a steel frame construction with fabric covering.
The Bristol Bloodhound was a British two-seat reconnaissance/fighter aircraft designed and built by the Bristol Aeroplane Company as a possible replacement for the Bristol F.2 Fighter for the Royal Air Force. It was unsuccessful, only four prototypes being built.
The Bristol Type 91 Brownie was a light sports aircraft produced in the United Kingdom by the Bristol Aeroplane Company in 1924. It was a low-wing cantilever monoplane aircraft of conventional configuration with fixed tailskid undercarriage. The pilot and passenger sat in tandem open cockpits. It won the £1,000 pound prize for second place at the Lympne light aircraft trials in October 1924.
The Westland Yeovil was a British biplane bomber designed and built by Westland Aircraft in 1923 to meet an Air Ministry specification for a single-engined day bomber.
The Westland Interceptor was a fighter developed by the British company Westland Aircraft to Air Ministry Specification F.20/27. When tested in 1929 and 1930, it showed unsatisfactory handling characteristics and was rejected by the RAF in favour of the Hawker Fury biplane fighter.
The Bristol Seely was entered into an Air Ministry competition for safe civil aeroplanes held in 1920. It was a single-engine biplane with accommodation for one passenger. After the competition, the single Seely was used as a testbed for the Bristol Jupiter engine development programme.
The Bristol Berkeley was built to a British government specification for a single-engine day or night bomber. Three of these two-seat biplanes were built, but no contract for further production was awarded.
The Airscrew Company Ltd was a British manufacturing company based in Surrey manufacturing propellers.
Hordern-Richmond was a British aeronautical engineering company that traded between 1937 and c. 1990.
The Handley Page Handcross was a single-engined biplane day bomber built to an Air Ministry specification. It was not put into production and only the three prototypes were built.
The sole Boulton & Paul P.32 was a British three-engined biplane built to an Air Ministry specification for a long range night bomber. A lack of engine availability slowed construction and by the time it went for tests the thinking on bomber types had moved on.
