Packard-Le Père LUSAC-11
The LUSAC-11 ("Lepère United States Army Combat") was an early American two-seat fighter aircraft. It was a French design, commissioned and built in the United States during World War I and ordered in large numbers by the United States Army Air Corps, but these were cancelled at the end of the war, and only 30 were built. The type was used for experimental purposes, setting several altitude records during the 1920s. Design and development When the U.S. entered World War I, the Signal Corps had just 55 aircraft,Fitzsimons 1978, p.1782. none fit for combat. The American Expeditionary Force was equipped with French types, and the LUSAC was part of a plan to build French designs in the U.S. Georges Lepère,Fitzsimons 1978, p. 1783. a member of the French Aeronautical Mission to the United States, was tasked by the Engineering Division of the United States Army Air Service to design a two-seat escort fighter. His design was a two-bay biplane with upper and lower wings of equal spa ... [...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 ...

Interplane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more imp ...

Dayton, Ohio
Dayton () is the sixth-largest city in the U.S. state of Ohio and the county seat of Montgomery County. A small part of the city extends into Greene County. The 2020 U.S. census estimate put the city population at 137,644, while Greater Dayton was estimated to be at 814,049 residents. The Combined Statistical Area (CSA) was 1,086,512. This makes Dayton the fourth-largest metropolitan area in Ohio and 73rd in the United States. Dayton is within Ohio's Miami Valley region, north of the Greater Cincinnati area. Ohio's borders are within of roughly 60 percent of the country's population and manufacturing infrastructure, making the Dayton area a logistical centroid for manufacturers, suppliers, and shippers. Dayton also hosts significant research and development in fields like industrial, aeronautical, and astronautical engineering that have led to many technological innovations. Much of this innovation is due in part to Wright-Patterson Air Force Base and its place in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McCook Field
McCook Field was an airfield and aviation experimentation station in Dayton, Ohio, United States. It was operated by the Aviation Section, U.S. Signal Corps and its successor the United States Army Air Service from 1917 to 1927. It was named for Alexander McDowell McCook, an American Civil War general and his brothers and cousins, who were collectively known as " The Fighting McCooks". History In 1917, anticipating a massive need for military airplanes by the United States during World War I, six Dayton businessmen including Edward A. Deeds formed the Dayton-Wright Company in Dayton, Ohio. In addition to building a factory in Moraine, Ohio, Deeds built an airfield on property he owned in Moraine for use by the company. Deeds was also interested in building a public aviation field along the Great Miami River approximately one mile (1.6 km) north of downtown Dayton, purchasing the property in March 1917. He called it North Field to differentiate it from the South Field in Mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fisher Body
Fisher Body was an automobile coachbuilder founded by the Fisher brothers in 1908 in Detroit, Michigan. A division of General Motors for many years, in 1984 it was dissolved to form other General Motors divisions. Fisher & Company (originally Alloy Metal Products) continues to use the name. The name and its iconic "Body by Fisher" logo were well known to the public, as General Motors vehicles displayed a "Body by Fisher" emblem on their door sill plates until the mid-1990s. Fisher brothers Fisher Body's beginnings trace back to a horse-drawn carriage shop in Norwalk, Ohio, in the late 1800s. Lawrence P. Fisher (1852 Peru, Ohio – 1921, Norwalk, Ohio) and his wife Margaret Theisen (1857 Baden, Germany – 1936 Detroit, Michigan) had a large family of eleven children; seven were sons who would become part of the Fisher Body Company in Detroit. Lawrence and Margaret were married in Sandusky, Ohio, in 1876. Margaret Theisen Fisher lived in Detroit after her husband died. The Fish ...

Brewster & Co
Brewster & Company was an American custom carriage-maker and automobile coachbuilder founded by James Brewster in 1810 and active for almost 130 years. Brewster began in New Haven, Connecticut and quickly established a reputation for building America's finest carriages. He opened his first New York City showroom at 52 Broad Street in 1827. Brewster's first known bodywork on an automobile was on an electric car in 1896, then a gasoline-powered Delaunay-Belleville chassis in 1905. Eventually they built bodies on chassis from a variety of makers, winning a particular link with Rolls-Royce America Inc at Springfield. Between 1915-1925 they produced a line of opulent and expensive automobiles at their plant in Long Island City. The Great Depression began in 1929 and luxury car sales declined. In 1934-35 they built and sold luxury bodies on 135 Ford V8 chassis, but bankruptcy proceedings began in mid-1935 and the last of Brewster's assets were sold by auction in 1937. Ownership O ...

Scarff Ring
The Scarff ring was a type of machine gun mounting developed during the First World War by Warrant Officer (Gunner) F. W. Scarff of the Admiralty Air Department for use on two-seater aircraft. The mount incorporated bungee cord suspension in elevation to compensate for the weight of the gun, and allowed an airgunner in an open cockpit to swivel and elevate his weapon (a Lewis machine gun) quickly, and easily fire in any direction. Later models permitted the fitting of two Lewis guns; while this doubled the firepower available, operation of the paired guns was more cumbersome, and required considerable strength from the gunner, especially at altitude, so that many gunners preferred the original single gun - and this became the postwar standard. In either case, the mounting was simple and rugged, and gave its operator an excellent field of fire. It was widely adapted and copied for other airforces. As well as becoming a standard fitting in the British forces during the First World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synchronization Gear
A synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon. Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 191 ...

Liberty L-12
The Liberty L-12 is an American water-cooled 45° V-12 aircraft engine displacing and making designed for a high power-to-weight ratio and ease of mass production. It saw wide use in aero applications, and, once marinized Marinisation (also marinization) is design, redesign, or testing of products for use in a marine environment. Most commonly, it refers to use and long-term survival in harsh, highly corrosive salt water conditions. Marinisation is done by many manu ..., in marine use both in racing and runabout boats. A single bank 6-cylinder version, the Liberty L-6, and V-8, the Liberty L-8, were derived from the Liberty L-12. It was succeeded by the Packard 1A-2500. Development In May 1917, a month after the United States had declared war on Germany, a federal task force known as the Aircraft Board, Aircraft Production Board summoned two top engine designers, Jesse G. Vincent (of the Packard Motor Car Company of Detroit) and Elbert J. Hall (of the Hall-Scott Motor Co. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
