Avro E
The Avro Type E, Type 500, and Type 502 made up a family of early British military aircraft, regarded by Alliott Verdon Roe as his firm's first truly successful design. It was a forerunner of the Avro 504, one of the outstanding aircraft of the First World War. Development The Type E biplane was designed in parallel with the slightly earlier Avro Duigan, differing principally in being slightly larger and having a more powerful () water-cooled E.N.V. engine. Both were two-bay tractor biplanes with unstaggered parallel-chord wings with rounded tips, a deep rectangular section fuselage bearing rectangular steel-framed stabilisers, elevators and rudder with no fixed fin, and an undercarriage with a pair of wheels on a transverse leaf-spring and a long central skid projecting forward of the propeller. This aircraft layout dominated aircraft design for twenty years: the Avro 500 and the contemporary B.E.2, B.E.1 are among the first truly practical examples built. Avro Duigan The A ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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".

Aspect Ratio
The aspect ratio of a geometry, geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, when the rectangle is oriented as a "landscape format, landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal Fraction (mathematics), fraction. The values x and y do not represent actual widths and heights but, rather, the proportion between width and height. As an example, 8:5, 16:10, 1.6:1, and 1.6 are all ways of representing the same aspect ratio. In objects of more than two dimensions, such as hyperrectangles, the aspect ratio can still be defined as the ratio of the longest side to the shortest side. Applications and uses The term is most commonly used with reference to: * Graphic / image ** Aspect ratio (image), Image aspect ratio ** Display aspect ratio ** Pape ...

British Admiralty
The Admiralty was a Departments of the Government of the United Kingdom, department of the Government of the United Kingdom that was responsible for the command of the Royal Navy. Historically, its titular head was the Lord High Admiral of the United Kingdom, Lord High Admiral – one of the Great Officers of State. For much of its history, from the early Admiralty in the 18th century, 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board (United Kingdom), Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence (United Kingdom), Ministry of Defence and its Navy Department (Ministry of Defence), Navy Department (later Navy Command (Ministry of Defence), Navy Command). Before the Acts of Union 1707, the Office of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1912 British Military Aeroplane Competition
In 1911 the British War Office announced their first Military Aeroplane Competition for aircraft to meet the requirements of the Air Battalion Royal Engineers. The formal requirements were published in December 1911. By the time the trials were held in August 1912, the Air Battalion had become the Military wing of the Royal Flying Corps (RFC). It was held at Larkhill on Salisbury Plain, and the competition was won by S. F. Cody with his Cody V biplane. "Specification for a Military Aeroplane" By 1911 it was clear that the development of aircraft had reached the point where they were of military significance. France, the world leader in aviation at the time, had over 200 aircraft in military service. In contrast, Britain's total military aircraft strength was nineteen aircraft, of which, in the words of Colonel J.E.B Seely, Under-Secretary of State for War, "one is broken beyond repair and one is quite out of date. Others are more or less under repair" adding "We are arriving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilfred Parke
Lieutenant Wilfred Parke RN (1889–1912) was a British flight instructor who was the first pilot to make an observed recovery from a spin. Family Parke was the son of Alfred Watlington Parke, the Rector of Uplyme, and Hilda Fort, and the grandson of Charles Joseph Parke. Career Parke became a midshipman in the Royal Navy in September 1905, was promoted to sub-lieutenant in 1908 and lieutenant in 1910.Aeroplane Accident at Wembley ''The Times'' Monday 16 Dec 1912; p. 4; Issue 40083. He had his first flying lesson at the Avro school at Brooklands on Sunday 11 April 1911. At that time dual-control instruction was almost unknown, and Parke was in sole charge of the aircraft, in which he had been told to try taxying. To the surprise of all, he opened the throttle, and made series of short hops, managing to land successfully. The following Wednesday Parke, at his third attempt, succeeded in flying a half-circle in a stiff breeze, landing with minor damage to the undercarriage. ...

Floatplane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call floatplanes "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, has greatly reduced the number of flying boats being built. However, many modern civilian aircraft have floatplane variants, most offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found their niche as one type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Sea Bird
The Lakes Sea Bird was a two-seat floatplane built during 1912 by the Lakes Flying Company using the fuselage of the Avro Duigan which had been built by Avro for John Robertson Duigan. It gave many visitors to Windermere their first flight in the summer of 1913 Development After Duigan damaged his aircraft and returned to Australia the fuselage and tail unit were sold to the Lakes Flying Co. based at Windermere, who rebuilt it as a two-seat floatplane. The straight parallel-chord high aspect ratio wings of irregular three-bay layout resembled those of Avro's Avro Type D. It was originally fitted with a single central two-step float, later changed to a pair of narrower floats, and demountable so that the aircraft could readily be used as a landplane. It was powered by a rotary 7-cylinder Gnome A gnome () is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors, inclu ...

Lakes Aircraft Co
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...
