Kocjan Czajka
The Czajka () or Kocjan Czajka after its designer was a Polish secondary training glider which was in continuous production from 1931 to the start of World War II. More than 160 were completed in Warsztaty Szybowcowe in Warsaw. Design and development Antoni Kocjan designed the Czajka 1931 at Aviation Section workshops of Mechanic Students' Club of Warsaw University of Technology (KMSPW) at Okęcie near Warsaw. It was intended to provide flight experience at a level between those of the low performing but easy to fly basic trainers and of the high performance cross-country sailplanes. The three prototypes ordered by the government were built here and the first flew on 31 April 1931. These prototypes demonstrated excellent flight characteristics and were popular with their pilots. Eighteen Czajkas in total were built at Okęcie. In 1932, the workshops were separated as Warsztaty Szybowcowe (Glider Workshops) in Warsaw, which undertook further production. The Czajka was a ...

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 ...

Ailerons
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in Flight dynamics, roll (or movement around the aircraft's Flight control surfaces#Longitudinal axis, longitudinal axis), which normally results in a change in flight path due to the tilting of the Lift (force), lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long Wright brothers patent war, legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the World War I, First World War compelled the U.S. Government to legislate a le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandatory Palestine
Mandatory Palestine ( ar, فلسطين الانتدابية '; he, פָּלֶשְׂתִּינָה (א״י) ', where "E.Y." indicates ''’Eretz Yiśrā’ēl'', the Land of Israel) was a geopolitical entity established between 1920 and 1948 in the region of Palestine under the terms of the League of Nations Mandate for Palestine.

The United Kingdom had agreed in the McMahon–Hussein Correspondence that it would honour Arab independence if the Arabs revolted against the Ottoman Turks, but the two sides had different interpretations of this agreement, and in the end, the United Kingdom and France divided the area under the Sykes–Picot Agreementan act of betrayal in the eyes of the Arabs.
