Bristol Grampus
The Bristol Grampus was a British prototype biplane passenger aircraft proposed by the British and Colonial Aeroplane Company but not built. Design and development Following the end of the First World War, the British and Colonial Aeroplane Company looked at producing a general-purpose passenger or cargo aircraft. Frank Barnwell proposed a single-engined biplane for six passengers, powered by a 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. Barnwell returned with a smaller three-passenger Grampus II powered initially by a RAF 4a air-cooled engine which would be replaced by the Siddeley Lynx radial engine on production aircraft. The directors did not approve of the design, nor of two eight-passenger variants also proposed. In February 1920 the project was abandoned as none of the designs appeared to meet the criteria for an Air Ministry competition. Varian ...

Passenger Aircraft
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body aircraft, wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for Flight length#long-haul, long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body aircraft, narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non-mainli ...

Bristol Aeroplane Company
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. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Barnwell
Captain Frank Sowter Barnwell OBE AFC FRAeS BSc (23 November 1880 – 2 August 1938) was a Scottish aeronautical engineer. With his elder brother Harold, he built the first successful powered aircraft made in Scotland and later went on to a career as an aircraft designer with the Bristol Aeroplane Company, designing aircraft such as the Bristol Fighter, the Bulldog and the Blenheim. Early life Barnwell was born in Lewisham in south east London but the family moved to Glasgow the year after his birth he and was educated at Fettes College in Edinburgh, after which he served a six-year apprenticeship with the Fairfield Shipbuilding and Engineering Company, of which his father was a partner, between 1898 and 1904. He attended the University of Glasgow at the same time and received a BSc in naval architecture in 1905. He then spent a year in America working as a draughtsman for a shipbuilder. Aviation career In 1907 he returned to Scotland and established the Grampian Motors & ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siddeley Tiger
The Siddeley Tiger was an unsuccessful British aero engine developed shortly after the end of World War I by Siddeley-Deasy. Problems encountered during flight testing caused the project to be cancelled. Design and development Developed using two modified cylinder banks from the Siddeley Puma, the Tiger was a liquid-cooled 60-degree V12 engine with the advanced feature of an electric starter motor protected by a friction clutch. A reduction gear arrangement was provided for the propeller drive with a ratio of 0.559:1. The company claimed a power output of 600 hp (447 kW) but this was regarded as optimistic.Gunston 1989, p.18. Flight testing by a Royal Aircraft Establishment test pilot, Frank Courtenay, revealed problems and his opinion of the engine was low as the following quote shows: Application and cancellation The Tarrant Tabor, a giant triplane bomber was designed to use the Tiger but redesigned to use other engines when it became clear the Tiger would not ...

Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
