Miles M.11 Whitney Straight
The Miles M.11 Whitney Straight was a 1930s twin-seat cabin monoplane designed and produced by the British aircraft manufacturer Miles Aircraft. It was named after Whitney Straight, a Grand Prix motor racing driver, aviator and businessman. The aircraft was the first combine a side-by-side seating arrangement with an enclosed cockpit for the general aviation sector. The Whitney Straight was developed after F.G. Miles and Straight recognised that they had similar ambitions to develop modern aircraft suited to flying clubs and private owners alike, and thus decided to collaborate on its production. On 14 May 1936, the first prototype conducted its maiden flight at Woodley Aerodrome; quantity production commenced shortly thereafter. Whitney Straights were used in various roles within the civil market, such as air racing and aerial topdressing. Approaches were also made by Miles to introduce the Whitney Straight into the military market. While not selected as an army coopera ...

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 ...

Impressment
Impressment, colloquially "the press" or the "press gang", is the taking of men into a military or naval force by compulsion, with or without notice. European navies of several nations used forced recruitment by various means. The large size of the British Royal Navy in the Age of Sail meant impressment was most commonly associated with Great Britain and Ireland. It was used by the Royal Navy in wartime, beginning in 1664 and during the 18th and early 19th centuries as a means of crewing warships, although legal sanction for the practice can be traced back to the time of Edward I of England. The Royal Navy impressed many merchant sailors, as well as some sailors from other, mostly European, nations. People liable to impressment were "eligible men of seafaring habits between the ages of 18 and 55 years". Non- seamen were sometimes impressed as well, though rarely. In addition to the Royal Navy's use of impressment, the British Army also experimented with impressment from 1778 to 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Split Flap
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

Vacuum
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But hig ...

Perspex
Poly(methyl methacrylate) (PMMA) belongs to a group of materials called engineering plastics. It is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. Chemically, it is the synthetic polymer of methyl methacrylate. It was developed in 1928 in several different laboratories by many chemists, such as William Chalmers, Otto Röhm, and Walter Bauer, and first brought ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Mile Whitney Straight Old Warden 6 Oct 2013 -1
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the British Commonwealth and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile, such as the nautical mile (now exactly), the Italian mile (roughly ), and the Chinese mile (now exactly). The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in Elizabethan-era England meant that the statute mile was made equivalent to or in 1593. This form of the mile then spread across the British Empire, some successor states of which conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's Cup Race
The King's Cup air race is a British handicapped cross-country event, which has taken place annually since 1922. It is run by the Royal Aero Club Records Racing and Rally Association. The King's Cup is one of the most prestigious prizes of the British air racing season. The entrants are divided into classes, and each is evaluated and given a time handicap for the start of the race. They all take off at varying times according to their handicap, with the handicappers' aim being that they should all cross the finishing line at the same moment. The art of winning the race outright is therefore to beat the handicappers, rather than to make the fastest flight as such.Alex Henshaw, ''The Flight of the Mew Gull'', Murray, 1980. p.95 The aircraft are also divided into classes, with a winner for each class as well as the outright winner. History The King's Cup air race was established by King George V as an incentive to the development of light aircraft and engine design. Initially, i ...

Philips And Powis
Miles was the name used between 1943 and 1947 to market the aircraft of British engineer Frederick George Miles, who, with his wife – aviator and draughtswoman Maxine Blossom Miles, Maxine "Blossom" Miles (née Forbes-Robertson) – and his brother George Herbert Miles, designed numerous light civil and military aircraft and a range of curious prototypes. History Phillips and Powis A company was founded in 1928 by Charles Powis and Jack Phillips as Phillips & Powis Aircraft (Reading) Ltd. In 1929 they opened Woodley Aerodrome, near the town of Reading, Berkshire, Reading, Berkshire. In 1936, Rolls-Royce Limited, Rolls-Royce bought into the company. Although aircraft were produced under the Miles name, it was not until 1943 that the firm became Miles Aircraft Limited when Rolls-Royce's interests were bought out. The company needed to increase production of the Miles Messenger and to do so it took over a former linen mill in Banbridge, County Down, Northern Ireland for the pr ...
