P.W.S.51
The PWS-51 was a Polish sports plane of 1930, a single-engine low-wing monoplane, constructed by the ''Podlaska Wytwórnia Samolotów'' (PWS), that remained a prototype. Design and development The plane was designed in 1929 by Stanisław Cywiński in ''Podlaska Wytwórnia Samolotów'', on factory's initiative, specially to participate in the Challenge 1930 international touring aircraft contest (along with PWS-50, PWS-52 and PWS-8). The plane was built with a financial help of LOPP organization and it was first flown in spring of 1930 by Franciszek Rutkowski in Biała Podlaska. It's noteworthy, that it was only 10 kg heavier, and its maximum speed was 15 km/h higher, than estimated. Operational history The prototype, with markings SP-ADC and contest number O7, took part in the Challenge 1930 international contest in July 1930, flown by Józef Lewoniewski. He completed most of a rally over Europe, but had to withdraw after a forced landing near Vienna on July 28, due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PWS-8
The P.W.S.8 was a 1930 Polish sports plane, constructed by the '' Podlaska Wytwórnia Samolotów'' (PWS), that remained a prototype. Design and development The plane was designed in 1929 by Jarosław Naleszkiewicz in ''Podlaska Wytwórnia Samolotów'', on factory's initiative, to participate in the Challenge 1930 international touring aircraft contest (with P.W.S.50, P.W.S.51 and P.W.S.52). It was a wooden biplane, partly modelled after de Havilland Gipsy Moth.Glass, A. (1977), p.184-185 Its unique feature, taken from earlier PWS military aircraft, like P.W.S.5, were N-shaped struts between lower and upper wing and additional oblique transverse struts, stiffening the design, instead of wire braces (similar bracing to Handley Page Gugnunc). The plane was first flown in 1929 or 1930 by F. Rutkowski, with Armstrong Siddeley Genet 80 hp radial engine. In spring of 1930 it was modified, with Walter Vega 85 hp radial engine, also a tailfin shape and some other details we ... [...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 ...

Lublin
Lublin is the ninth-largest city in Poland and the second-largest city of historical Lesser Poland. It is the capital and the center of Lublin Voivodeship with a population of 336,339 (December 2021). Lublin is the largest Polish city east of the Vistula River and is about to the southeast of Warsaw by road. One of the events that greatly contributed to the city's development was the Polish-Lithuanian Union of Krewo in 1385. Lublin thrived as a centre of trade and commerce due to its strategic location on the route between Vilnius and Kraków; the inhabitants had the privilege of free trade in the Grand Duchy of Lithuania. The Lublin Parliament session of 1569 led to the creation of a real union between the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, thus creating the Polish–Lithuanian Commonwealth. Lublin witnessed the early stages of Reformation in the 16th century. A Calvinist congregation was founded and groups of radical Arians appeared in the city ...

1930s Polish Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor.

Armstrong Siddeley Genet
The Armstrong Siddeley Genet was a five-cylinder, air-cooled, radial engine for aircraft use built in the UK, first run in 1926. It developed 80 hp at 2,200 rpm in its final form and was a popular light aircraft powerplant. Following the company tradition with a slight deviation the engine was named after the Genet, a catlike animal of the same order but different family.

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 ...

Monoplane
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 ...

Podlasie
Podlachia, or Podlasie, ( pl, Podlasie, , be, Падляшша, translit=Padliašša, uk, Підляшшя, translit=Pidliashshia) is a historical region in the north-eastern part of Poland. Between 1513 and 1795 it was a voivodeship with the capital in Drohiczyn. Now the part north of the Bug River is included in the modern Podlaskie Voivodeship with the capital in Białystok. Names and etymology The region is called , or in Polish, in Lithuanian, ''Padliašša'' (Падляшша) in Belarusian, ''Pidljaššja'' (Підляшшя), ''Pidljassja'' (Підлясся), ''Pidljasije'' (Підлясіє), or ''Pidljaxija'' (Підляхія) in Ukrainian, ''Podljas’e'' (Подлясье) in Russian, "Podlyashe" (פּאָדליאַשע) in Yiddish, and in Latin. There are two hypotheses regarding the origin of the name of the region. According to the first one, the name is derived from the Polish word ''las'' ("forest"), and means "near the forest".
