Bristol Type 143
The Bristol Type 143 was a British twin-engine monoplane aircraft designed by Frank Barnwell of the Bristol Aeroplane Company. Developed alongside the more famous Bristol Type 142, which was developed into the Blenheim light bomber, it used the same wing design and employed the same advanced (for the day) design features such as stressed skin, flaps, and retractable undercarriage. The engine it was designed to use never entered production and only a single prototype was manufactured, Design and development Like the better-known Type 142 the Type 143 arose from the unbuilt Bristol Type 135 proposal for a civil twin-engine light transport aircraft. This was a low-wing twin-engined monoplane, seating six people and a crew of two, first sketched out by Frank Barnwell, with the intention of using the smaller of the two engines then being developed by Roy Fedden, the Aquila I. Although the manufacture of a second Aquila was authorised, nothing was done about the construction of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bristol 143 F 3-view NACA-SR-26
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

1930s British Civil Utility Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...

Lockheed Model 10 Electra
The Lockheed Model 10 Electra is an American twin-engined, all-metal monoplane airliner developed by the Lockheed Aircraft Corporation in the 1930s to compete with the Boeing 247 and Douglas DC-2. The type gained considerable fame as one was flown by Amelia Earhart on her ill-fated around-the-world expedition in 1937. Design and development Some of Lockheed's wooden designs, such as the Orion, had been built by Detroit Aircraft Corporation with metal fuselages. However, the Electra was Lockheed's first all-metal and twin-engined design by Lloyd Stearman and Hall Hibbard. The name Electra came from a star in the Pleiades. The prototype made its first flight on February 23, 1934, with Marshall Headle at the controls. Wind-tunnel work on the Electra was undertaken at the University of Michigan. Much of the work was performed by a student assistant, Clarence Johnson. He suggested two changes be made to the design: changing the single tail to double tails (later a Lockheed trade ...

Airspeed Envoy
The Airspeed AS.6 Envoy was a twin-engined light transport aircraft designed and produced by the British aircraft manufacturer Airspeed Ltd. The Envoy originated as a heavier twin-engine derivative of Airspeed's Courier light transport aircraft. Sharing much of its design with this earlier aircraft, it was relatively easy to develop; confidence in the project was so high that within a week of the prototype's maiden flight, it was performing as a display aircraft to the public. Quantity production of the Envoy had been initiated even before this first flight. Early on, Airspeed worked closely with the British engine manufacturer Wolseley Motors as both a key supplier and early custom of the Envoy; development subsequently branched out to a wide variety of engines and configurations. The majority of Envoys were produced by Airspeed at their facility at Portsmouth Aerodrome, Hampshire. The type was also produced overseas in Japan by Mitsubishi following the acquisition of a lic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Aquila I
The Aquila was a nine-cylinder single-row radial aircraft engine designed by the Bristol Engine Company starting in 1934. A sleeve valve engine, its basic design was developed from the Bristol Perseus. The Aquila was never used in production, but further developments led to the Bristol Hercules, Bristol Taurus, and Bristol Centaurus. Design and development The Aquila was developed two years after the somewhat larger Perseus, both being sleeve valve designs. The primary difference was in size, the Perseus being based on the cylinder used in the Mercury engine, while the Aquila used a new and smaller sized cylinder. The result was a reduction in displacement from 1520 to 950 cubic inches (24.9 to 15.6 L). The first Aquila engine delivered a modest , which was unspectacular for an engine of this size. It soon developed into more powerful versions as improvements were worked into the line (as well as similar changes to the Perseus), and by 1936 it had improved to . This would ha ...
