The Bristol Grampus was a British prototype biplane passenger aircraft proposed by the British and Colonial Aeroplane Company but not built.
Following the end of the First World War, the British and Colonial Aeroplane Company looked at producing a general-purpose passenger or cargo aircraft. [1] Frank Barnwell proposed a single-engined biplane for six passengers, powered by a 500 hp (373 kW) Siddeley Tiger engine and named Grampus I. The directors of the company thought it too large for the proposed market and were concerned about the supply of Tiger engines. [1] Barnwell returned with a smaller three-passenger Grampus II powered initially by a 150 hp (112 kW) RAF 4a air-cooled engine which would be replaced by the Siddeley Lynx radial engine on production aircraft. [1] The directors did not approve of the design, nor of two eight-passenger variants also proposed. [1] In February 1920 the project was abandoned as none of the designs appeared to meet the criteria for an Air Ministry competition. [1]
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.
The Bristol Pegasus is a British nine-cylinder, single-row, air-cooled radial aero engine. Designed by Roy Fedden of the Bristol Aeroplane Company, it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Mercury and Jupiter engines, later variants could produce 1,000 horsepower from its capacity of 1,750 cubic inches by use of a geared supercharger.
The Bristol Bulldog is a British Royal Air Force single-seat biplane fighter designed during the 1920s by the Bristol Aeroplane Company. More than 400 Bulldogs were produced for the RAF and overseas customers, and it was one of the most famous aircraft used by the RAF during the inter-war period.
The Hawker Hart is a British two-seater biplane light bomber aircraft that saw service with the Royal Air Force (RAF). It was designed during the 1920s by Sydney Camm and manufactured by Hawker Aircraft. The Hart was a prominent British aircraft in the inter-war period, but was obsolete and already side-lined for newer monoplane aircraft designs by the start of the Second World War, playing only minor roles in the conflict before being retired.
The Bristol F.2 Fighter is a British First World War two-seat biplane fighter and reconnaissance aircraft developed by Frank Barnwell at the British and Colonial Aeroplane Company later known as the Bristol Aeroplane Company. It is often simply called the Bristol Fighter, "Brisfit" or "Biff".
The Westland Wapiti was a British two-seat general-purpose military single-engined biplane of the 1920s. It was designed and built by Westland Aircraft Works to replace the Airco DH.9A in Royal Air Force service.
The Bristol Braemar was a British heavy bomber aircraft developed at the end of the First World War for the Royal Air Force. Only two prototypes were constructed.
The Bristol Pullman was a British prototype passenger aircraft developed from the Braemar triplane heavy bomber.
The Bristol Tramp was a British steam-powered passenger and airmail transport aircraft designed by the Bristol Aeroplane Company. It was built but never flew.
The Bristol M.1 Monoplane Scout was a British monoplane fighter of the First World War. It holds the distinction of being the only British monoplane fighter to reach production during the conflict.
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 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 Bullfinch was an experimental British military aircraft first flown in 1922. Variants were built as both parasol wing monoplanes and biplanes, but both versions proved unsuccessful, and only the three prototypes were built.
The Bristol Type 99 Badminton was a 1920s British single-seat racing biplane built by the Bristol Aeroplane Company and designed by F.S. Barnwell.
The Bristol Babe was a British-built light single-seat biplane, intended for the private flyer and produced immediately after the First World War. Only two flew.
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 Type 110A was a single-engine biplane for charter work, accommodating four passengers in comfort. Designed by Frank Barnwell and built at Filton Aerodrome by the Bristol Aeroplane Company. No orders were obtained and only one aircraft was built.
The Bristol Scout E and F were a British single-seat biplane fighters built in 1916 to use newer and more powerful engines. It was initially powered by the Sunbeam Arab, but the third prototype was used as a testbed for the Cosmos Mercury, marking the start of Roy Fedden's association with the Bristol Aeroplane Company. The Armistice ended hopes of production.
The Fairey Ferret was a 1930s British general-purpose biplane designed and built by the Fairey Aviation Company. It performed well in trials but was not ordered into production.
The RAF 4 is a British air-cooled, V12 engine developed for aircraft use during World War I. Based on the eight–cylinder RAF 1 it was designed by the Royal Aircraft Factory but produced by the two British companies of Daimler and Siddeley-Deasy. The RAF 5 was a pusher version of the same engine.
