Silesia S-4
The Silesia S-4 was a Polish, low-power parasol wing aircraft built in 1925. After an engine change and airframe modifications it became one of the Silesian Aeroclubs fleet. It was lost in a take-off accident in 1931 and was the last Silesia aircraft to fly. Design and development Three brothers, Edward, Paul and Wojciech Sopora set up an aircraft-building workshop in 1923 at Chorzów, calling it the Pierwsza Śląska Fabryka Samolotów (First Silesian Aircraft Factory). Their first product was the 1923 Silesia S-3. Though their next aircraft, the 1925 Silesia S-4, was also a low-powered, single seat monoplane like the S-3, It was a parasol wing type of more refined design. The wing, with a rectangular plan and a thin aerofoil section, was a one piece, wooden structure built around two spars and fabric-covered. It was braced on each side with a parallel pair of struts to the spars from the lower fuselage longerons. An unusual pyramid of long struts on each side from the mid an ...

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 ...

Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasol-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 ...

Cabane 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 impo ...

Anzani
Anzani was an engine manufacturer founded by the Italian Alessandro Anzani (1877–1956), which produced proprietary engines for aircraft, cars, boats, and motorcycles in factories in Britain, France and Italy. Overview From his native Italy, Anzani moved to France where he became involved in cycle racing. He moved on to motorcycles and designed and built a record breaking lightweight engine. In 1907, he set up a small workshop in Paris with three staff and while they were building his engines, he designed a hydrofoil powered by one of his engines and propellers. Aircraft engines He supplied one of his engines to Enrico Forlanini and developed it further into a three-cylinder, air-cooled, radial engine ideal for the new aeroplanes. One of the early engines, the 25 hp Anzani W-3 or Fan type, was supplied to Louis Blériot who used it on his successful first aircraft crossing of the English Channel in 1909. Types * Anzani 3-cyl.

Airborne And Antigas Defence League
Air and Chemical Defense League (Polish: ''Liga Obrony Powietrznej i Przeciwgazowej'', ''L.O.P.P.'') was a mass Poland, Polish paramilitary organization, founded in 1928 as a result of the merger of the ''State Air Defense League'' (Polish: ''Liga Obrony Powietrznej Panstwa'') with the Gas Defense Society (Polish: ''Towarzystwo Obrony Przeciwgazowej''). In 1937 it numbered some 1.5 million members, with 14,000 local branches. It had a national character, gathering enthusiasts of aircraft, communications and ballooning.

By 1925 A Schreck FBA 17 HMT2 was operated by LOPP with funds raised by contributions from the readers of ''Głos Lubelski''. After the merger The League backed in all possible ways purchases of aviation equipment, development of aircraft as well as various airforce-oriented publication ...
