SZD-12 Mucha 100
The SZD-12 Mucha 100 (''Szybowcowy Zakład Doświadczalny'' - Glider Experimental Works) was a single-seat glider aircraft that was designed and built in Poland from 1953. Development The SZD-12 Mucha (''Fly'') 100 was derived from the IS-2 Mucha-ter for use by aero clubs throughout Poland. Two hundred and ninety were built with 73 exported to several countries and an unknown number were licence-built in the People's Republic of China (PRC). Constructed from wood/plywood throughout, the Mucha 100 was much improved from the IS-2 Mucha, with smoother surfaces, better aerodynamics and comprehensive instruments and equipment including a KF-18 oxygen system, lighting and instruments for cloud flying. Pilot comfort was improved by slightly reclining the seat back and increasing legroom, and visibility was increased through a larger one-piece cockpit canopy. Schempp-Hirth style airbrakes replaced the DFS style airbrakes of the IS-2, external mass balances fitted to the ailerons cu ...

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 ...

People's Republic Of China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

1950s Polish Sailplanes
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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 * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger. The Roman province of Mesopotamia rises in revolt with Parthian support.

Slingsby Skylark 2
The Slingsby T.41 Skylark 2 was a sailplane produced from 1953 by Slingsby Sailplanes at Kirkbymoorside, Yorkshire. Design and development Following the technical success of the T.37 Skylark, the concept was expanded with the introduction of the T.41 Skylark 2. The use of laminar-flow sections was continued but the section at the tips was changed to NACA4415 to reduce the tendency to tip-stall. The Skylark 2 was very similar in shape to its predecessor but had a smooth-skinned rounded fuselage and a wing of greater span and area. Composite materials were introduced in the Skylark 2, with the nose cone, wingtips and various small fairings made from polyester resin glassfibre. The thickness of the aerofoils was increased to ensure that drag was reduced over a wider speed range allowing the Skylark 2 to climb faster in thermals at low speed and race between thermals at high speed. History The prototype was flown in November 1953 and tested by the British Gliding Association's Tes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bielsko
Bielsko (german: Bielitz, cs, Bílsko) was until 1950 an independent town situated in Cieszyn Silesia, Poland. In 1951 it was joined with Biała Krakowska to form the new town of Bielsko-Biała. Bielsko constitutes the western part of that town. Bielsko was founded by the Cieszyn Piast dukes in the late 13th century on the grounds of village later called Stare Bielsko (''Old Bielsko''), on the Biała River. It was first mentioned in a written document in 1312. Originally settled by Germans, it became the largest German-language center (''Deutsche Sprachinsel Bielitz'') in the Duchy of Teschen, and remained so until the end of World War II. In 1572 it gained autonomy as the Duchy (State) of Bielsko. During the 18th century a rapid development of textile industry occurred, and at the beginning of the 19th century more than 500 weavers worked in the town. After the 1920 division of Cieszyn Silesia between Poland and Czechoslovakia it became, despite the protests of local Germa ...
