Folkerts SK-3
The Folkerts SK-3 a.k.a. ''"Jupiter, Pride of Lemont"'' was the third in a series of air racers developed by Clayton Folkerts. Design and development The SK-3 was built for mechanic Rudy A. Kling from Lemont, Illinois as his personal racing aircraft. Kling assisted in the construction of the aircraft. The Folkerts SK-2 was the basis for the aircraft, with a slight upscaling in size with a larger Menasco C6-S engine. The SK-3 was a midwinged conventional aircraft with retractable landing gear. The fuselage was long and slender. The thin wings used spruce spars, plywood covering, and incorporated split flaps. The fuselage was welded steel tubing with aircraft fabric covering, built in two parts that were bolted together. The manual retractable landing gear used a single lever, rather than earlier crank systems. There were two forward fuel tanks, a main, and an auxiliary of mounted behind the cockpit. The Menasco C6-S was modified by Kling to produce at 3300 rpm, versus the sta ... [...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 ...

Aircraft Fabric Covering
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped ''Wickelrumpf'' plywood strip and fabric covering. Early aircraft used organic materials such as cotton and cellulose nitrate dope; modern fabric-covered designs usually use synthetic materials such as Dacron and butyrate dope for adhesive. Modern methods are often used in the restoration of older types that were originally covered using traditional methods. Purpose/requirements The purposes of the fabric covering of an aircraft are: * To provide a light airproof skin for lifting and control surfaces. * To provide structural strength to otherwise weak structures. * To cover other non-lifting parts of an airc ...

Mid-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Folkerts SK-1
The Folkerts SK-1,Speed King One, Mono Special, Matilda, Fordon-Neumann Special, Hardwick-Whittenbeck Special was a racer built for the 1930 American Cirrus Aircraft Engine Company sponsored American Cirrus Derby. Design and development Clayton Folkerts designed the "Mono Special" while working for the Mono-Aircraft Corporation. It was later renamed the SK-1.''Sport Aviation,'' September 1958 The aircraft was a strut-braced mid-winged conventional geared aircraft with a slender tapered tail and undersized wheels and fairings. Operational history In 1930, for the American Cirrus Derby, pilot John Livingston was hired, but Stub Quimby flew in his place after an illness. The team did not win any earnings. In the 1930 National Air Races, Quimby placed fourth in the 650 Cubic inch class at 142 mph. In the 1933 American Air Races, the aircraft was renamed the Folkerts SK-1, with modified lift struts and addition of wheel pants. The aircraft won first place twice in the 350 c ...

Menasco C6S
The Menasco Buccaneer was a series of popular six-cylinder, air-cooled, in-line, inverted, aero-engines, that were manufactured by Menasco Motors Company for light general aviation and sport aircraft during the 1930s and 1940s. The six-cylinder Menasco engines had the name Buccaneer, while the four-cylinder engines had the name Pirate. The Menasco engines came in both supercharged and normally aspirated models. The supercharged models, with the ''S'' suffix added to their designation, had superior performance at higher altitudes with a relatively small increase in dimensions and weight.

Aeroelasticity
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow; and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight and withstand large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the angle of attack of a wing which further increases the force; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases, reverses the control effectiveness; and # flutter which is the uncontained vibration that can lead ...

Roger Don Rae
Roger is a given name, usually masculine, and a surname. The given name is derived from the Old French personal names ' and '. These names are of Germanic origin, derived from the elements ', ''χrōþi'' ("fame", "renown", "honour") and ', ' ("spear", "lance") (Hrōþigēraz). The name was introduced into England by the Normans. In Normandy, the Frankish name had been reinforced by the Old Norse cognate '. The name introduced into England replaced the Old English cognate '. ''Roger'' became a very common given name during the Middle Ages. A variant form of the given name ''Roger'' that is closer to the name's origin is ''Rodger''. Slang and other uses Roger is also a short version of the term "Jolly Roger", which refers to a black flag with a white skull and crossbones, formerly used by sea pirates since as early as 1723. From up to , Roger was slang for the word "penis". In ''Under Milk Wood'', Dylan Thomas writes "jolly, rodgered" suggesting both the sexual double entend ...

National Air Races
The National Air Races (also known as Pulitzer Trophy Races) are a series of pylon and cross-country races that have taken place in the United States since 1920. The science of aviation, and the speed and reliability of aircraft and engines grew rapidly during this period; the National Air Races were both a proving ground and showcase for this. History In 1920, publisher Ralph Pulitzer sponsored the Pulitzer Trophy Race and the Pulitzer Speed Trophy for military airplanes at Roosevelt Field, Long Island, New York, in an effort to publicize aviation and his newspaper. The races eventually moved to Cleveland, where they were known as the Cleveland National Air Races.''about the Reno Air Racing Association'' Retrieved 2010-03-10.

Wittman Chief Oshkosh
Chief Oshkosh Buster is a homebuilt racing plane designed to compete in the 1931 American Cirrus Races. Development Steve Wittman started air racing in 1926 in various aircraft. In March 1931, he designed his own purpose built aircraft in Oshkosh, Wisconsin, "Chief Oshkosh". He was racing in Cleveland by August of the same year. His goal was to keep the plane light so that he could be the first to round a pylon and establish position. Design The "Chief Oshkosh" racer was a mid-winged taildragger with undersized wheels and tires without brakes. The original was powered by an American Cirrus engine, the 1932 racer was outfitted with a 349 Cubic inch Cirrus Hermes. In 1934, a smaller wing was fitted to the plane. In 1936 the plane was fitted with a Menasco CS-4 363 cubic inch engine and multiple leaf spring gear. The wing was also reduced again to . In 1937, a single piece steel landing gear was used, becoming the standard on Cessna aircraft of the future. In 1947 "Chief Oshk ...

Travel Air 2000, 3000 And 4000
The Travel Air 2000/3000/4000 (originally, the Model A, Model B and Model BH were open-cockpit biplane aircraft produced in the United States in the late 1920s by the Travel Air Manufacturing Company. During the period from 1924–1929, Travel Air produced more aircraft than any other American manufacturer, including over 1,000 biplanes. While an exact number is almost impossible to ascertain due to the number of conversions and rebuilds, some estimates for Travel Air as a whole range from 1,200 to nearly 2,000 aircraft.Wilkinson, 28 February 2014, pp.? Design and development Design and development The Travel Air Model A was engineered chiefly by Lloyd Stearman, with input from Travel Air co-founders Walter Beech, Clyde Cessna, and Bill Snook and could trace its ancestry back to the Swallow New Swallow biplane. The Travel Air, however, replaced the New Swallow's wooden fuselage structure with a welded steel tube. An interim design, the Winstead Special, was developed by ...
