Blackburn AD Scout
The AD Scout (also known as the Sparrow) was designed by Harris Booth of the British Admiralty's Air Department as a fighter aircraft to defend Britain from Zeppelin bombers during World War I. Design and development The Scout was a very unconventional aircraft – a biplane with a fuselage pod mounted on the ''upper'' wing. A twin-rudder tail was attached by four booms, and it was provided with an extremely narrow-track undercarriage. The primary armament was intended to be a 2-pounder recoilless Davis Gun, but this was never fitted. Four prototypes were ordered in 1915, and two each were built by Hewlett & Blondeau and the Blackburn Aeroplane & Motor Company. Operational history Trials flown by pilots of the Royal Naval Air Service at Chingford proved the aircraft to be seriously overweight, fragile, sluggish, and difficult to handle, even on the ground. The project was abandoned, and all four prototypes were scrapped. Operators ; *Royal Naval Air Service Specificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Twin-boom Aircraft
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

1910s British Fighter Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 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.

Air Department Aircraft
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Gravity of Earth, Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating Atmospheric pressure, pressure allowing for Water#Liquid water, liquid water to exist on the Earth's Planetary surface, surface, absorbing ultraviolet Solar irradiance, solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between Daytime, day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% Carbon dioxide in Earth's atmosphere, carbon dioxide, and small amounts of other gases. Air also contains a variable amount of Water vapor#Water vapor in Earth's atmosphere, water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, tempera ...

Davis Gun
The Davis gun was the first true recoilless gun developed and taken into service. It was developed by Commander Cleland Davis of the United States Navy in 1910, just prior to World War I. Development Davis' design connected two guns back to back, with the backwards-facing gun loaded with lead balls and grease of the same weight as the shell in the other gun, acting as a counter. His idea was used experimentally by the British and Americans as an anti-Zeppelin and anti-submarine weapon mounted on the British Handley Page O/100 and O/400 bombers and the American Curtiss Twin JN and Curtiss HS-2L and H-16 flying boats. The direct development of the gun ended with the end of World War I in November 1918, but the firing principle has been copied by later designs. Description The gun was made in three sizes 2-pounder, 6-pounder and 12-pounder; , , and in caliber respectively, firing , , and shells. The 3-inch gun carried a pressure of 15 tons per square inch (2,109 kg per cm2) whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnome Monosoupape 9 Type B-2
The ''Monosoupape'' ( French for single-valve), was a rotary engine design first introduced in 1913 by Gnome Engine Company (renamed Gnome et Rhône in 1915). It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the ''Monosoupape'' engines some of the most reliable of the era. British aircraft designer Thomas Sopwith described the ''Monosoupape'' as "one of the greatest single advances in aviation". Produced under license in both seven and nine-cylinder versions in large numbers in most industrialized countries including Germany (by Oberursel), Russia, Italy, Britain and the US. Two differing nine-cylinder versions were produced, the 9B-2 and 9N, with differing displacements giving the larger displacement 9N version a nearly-cylindrical shaped crankcase, with the 9N also adopting a dual ignition system for increased flight safety. 2,188 units wer ...

Chingford
Chingford is a town in east London, England, within the London Borough of Waltham Forest. The town is approximately north-east of Charing Cross, with Waltham Abbey to the north, Woodford Green and Buckhurst Hill to the east, Walthamstow to the south, and Edmonton and Enfield to the west. It contains the areas of Chingford Green, Chingford Hatch, Chingford Mount, Friday Hill, Hale End, Highams Park, and South Chingford, and had a population of 70,583 at the 2021 census. Prior to becoming part of the ceremonial county of Greater London in 1965, Chingford was in the historic county of Essex, where it was a civil parish, urban district and municipal borough, and historically formed an ancient parish in the Waltham hundred. Similar to much of south-west Essex, the town expanded significantly in the late 19th century, forming part of the conurbation of London. It was included in the Metropolitan Police District in 1840 and became part of London's postal district upon its incepti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hewlett & Blondeau
Hewlett & Blondeau was a manufacturer of aeroplanes and other equipment based in Leagrave, Luton, England which produced more than 800 aeroplanes and employed up to 700 people. History The company was formed by Hilda Hewlett and Gustav Blondeau. The two met at Brooklands, Surrey where Blondeau had opened his own flying school. Hewlett was the first British woman to earn a pilot's licence. Together they formed "Hewlett and Blondeau" and built Farman, Avro, Caudron and Hanriot aircraft under licence. They were the first company to build Caudron aircraft in Britain. The first factory was a disused ice-skating rink called The Omnia Battersea, London, where eventually they produced ten different types of aircraft. In May 1914, Hewlett & Blondeau purchased a field in Leagrave, Bedfordshire, specifically to build Farman aircraft. In order to retain links with its former base in Clapham, the firm kept the old telegraphic address 'Aeromnia', and named the factory The Omnia Works. Wh ...
