Arup S-1
The Arup S-1, also called the Snyder Glider and the Dirigiplane was the first in a series of "Heel Lift" vehicles developed by Dr. Cloyd Snyder. Development Snyder was a podiatrist in South Bend, Indiana. He was inspired in 1926 by the gliding properties of heel-lifts to develop a full size aircraft. Experimentation was performed on balsa-wood aircraft, followed by wind testing on the hood of a car, at South Bend Central High School and finally at Michigan University. Students at the school, led by S. M. Pierce, tested and built a wood and fabric glider based on the designs. Design The glider featured two wooden parallel trusses running along its spine, with two widely spaced truss wing spars. Wing ribs were attached to the spar with varnished shoelaces. The wing shape featured a straight leading edge with the trailing edge tapering back to the tail giving it a distinctive "Half Pie" appearance from the top. The vertical stabilizers were low, but ran the full length of the ... [...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 ...

Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 1932
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Arup S-4
The Arup S-4 (Model 104) is the last in a series of round-wing aircraft from C.L. Snyder. Design and development The S-4 was engineered by Raoul Hoffman. The test pilot was Glenn Doolittle, a cousin of Jimmy Doolittle. The S-4 used a low aspect ratio, semi-circular planform wing with a conventional landing gear and a small rudder with attached elevator on the rear of the fuselage. The aircraft was entered through a door mounted on the bottom of the aircraft. Operational history The S-4 prototype flew extensively in promotional demonstrations. The S-4 was emblazoned with Sears Roebuck and Company logos. The aircraft was scrapped for war materials in World War II. Variants * Hoffman Flying Wing a design based on the Arup S-4 aircraft. * Milt Hatfield Little Bird The Hatfield Little Bird aircraft are a continuation of the Arup series of low aspect ratio aircraft.

Arup S-3
The Arup S-3 was the third in a series of low aspect ratio aircraft developed by Dr. Snyder of South Bend, Indiana. Design and development Raoul Hoffman worked to engineer the Arup S-2 with Dr. Snyder. Around 1933 he was diagnosed with tuberculosis and left the company for the warmer climate of Florida where he developed his own variation, the Hoffman Flying Wing. He was replaced by Ralph Graigen to develop the next generation of the aircraft. The S-3 featured a straight leading edge with the trailing edge tapering back to the rear of the aircraft, giving it a thumbnail like appearance from the top. The aircraft featured a tall tricycle landing gear with a small tailwheel in case of over-rotation on takeoff. The fabric covered fuselage was made of welded steel tube with wooden wing ribs. The S-3 differed from the S-2 in that it included a small rudder and elevator at the rear of the fuselage, rather than placing all of the controls on the low aspect ratio wing. The fuselage was ...

Arup S-2
The Arup S-2 was the first commercial development of Cloyd Snyder's Arup S-1 low aspect ratio wing aircraft. Design The Arup S-2 featured a straight leading edge wing with a trailing edge that tapered to the rear of the aircraft giving it a guitar pick shape when viewed from above. An M6 airfoil was chosen over its predecessor's sharp edged, modified Clark-Y airfoil. The large trailing edge control surfaces were mixed for pitch and roll control, but were assisted by small, movable, semi-circular wingtips that could provide additional roll control. Conventional landing gear was used, faired with wheel pants. The access to the cockpit was from a belly mounted hatch. Visibility was enhanced with celluloid panels on the aircraft's belly. Operational history The prototype S-2 was test flown by Glen Doolittle. The STOL aircraft could fly at up to 35 degrees angle of attack without stalling. The aircraft was demonstrated across the country at events like the Indianapolis 500 and the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heath-Henderson B-4
The Heath-Henderson B-4 engine was a motorcycle piston engine modified for use in aircraft. "The Heath Airplane Company's Model B-4 was an in-line, four-cylinder, air-cooled Henderson motorcycle engine converted for use in aircraft by modifying the lubrication system and the valves. The B-4 mainly powered the small and economical Heath Parasol monoplane, which Heath sold in kit form for homebuilders in the 1920s and '30s." "The low-cost, reliable Henderson motorcycle engine was well-suited for the Heath airplane design because it helped make sport flying affordable for many people. Service was simple and economical because parts were cheap and easy to obtain throughout the country." * A Heath-Henderson engine was featured on an episode of the television show American Pickers, first airing on December 12, 2011 in the U.S. A brief history of both the Henderson motocycle company and use of the engine in Heath aircraft was discussed.

Clark-Y
Clark Y is the name of a particular airfoil profile, widely used in general purpose aircraft designs, and much studied in aerodynamics over the years. The profile was designed in 1922 by Virginius E. Clark using thickness distribution of the German-developed Goettingen 398 airfoil.Piccirillo, Albert, "The Clark Y Airfoil - A Historical Retrospective," SAE/AIAA paper 2000-01-5517, presented at the World Aviation Congress & Exposition, October 10, 2000, San Diego, California. The airfoil has a thickness of 11.7 percent and is flat on the lower surface aft of 30 percent of chord. The flat bottom simplifies angle measurements on propellers, and makes for easy construction of wings. For many applications the Clark Y has been an adequate airfoil section; it gives reasonable overall performance in respect of its lift-to-drag ratio, and has gentle and relatively benign stall characteristics. But the flat lower surface is not optimal from an aerodynamic perspective, and it is rarely used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicholas-Beazley Airplane Company
Nicholas-Beazley Airplane Company was an American aircraft manufacturer of the 1920s and 1930s History In 1921, the Nicholas-Beazley Airplane Company was founded by Russell B. (Penny) Nicholas and Howard Beazley. Nicholas started Central Aviation Company reselling surplus propellers, and in 1924 renamed the company to reflect the addition of Howard Beazley as partner. Nicholas-Beazley Airplane Company started as a reseller of surplus Curtiss OX-5 parts through mail-order catalogs, expanding into a wide variety of airplane construction materials. Nicholas-Beazley resold 57 Armstrong-Siddeley Genet engines originally sold by Fairchild, becoming the US distributor. Surplus Standard J aircraft were modified and marketed by the company. In 1927, Walter Barling was hired to engineer the first in-house aircraft, the Barling NB-3. The aircraft was advertised as being able to right itself from any position with the hands off the controls, and spin-proof. In 1929, Tom Kirkup was hired to ...

Pathé News
Pathé News was a producer of newsreels and documentaries from 1910 to 1970 in the United Kingdom. Its founder, Charles Pathé, was a pioneer of moving pictures in the silent era. The Pathé News archive is known today as British Pathé. Its collection of news film and movies is fully digitised and available online. History Its roots lie in 1896 Paris, France, when Société Pathé Frères was founded by Charles Pathé and his brothers, who pioneered the development of the moving image. Charles Pathé adopted the national emblem of France, the cockerel, as the trademark for his company. After the company, now called Compagnie Générale des Éstablissements Pathé Frère Phonographes & Cinématographes, invented the cinema newsreel with ''Pathé-Journal''. French Pathé began its newsreel in 1908 and opened a newsreel office in Wardour Street, London in 1910. The newsreels were shown in the cinema and were silent until 1928. At first, they ran for about four minutes and were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
