Kroeber M4 Köller
The Kroeber M4 Köller was a 2-stroke air-cooled horizontally opposed piston engine designed and built by Dr. Kroeber & Sohn G.m.b.H. in Germany in the late 1930s. The M4 proved relatively popular, for powering the ultra-light aircraft and motor-gliders in vogue during the 1920s and 1930s.

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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 outsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Germany
Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of Germany, constituent states have a total population of over 84 million in an area of , making it the most populous member state of the European Union. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The Capital of Germany, nation's capital and List of cities in Germany by population, most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in the territory of modern Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic peoples, Germanic tribes have inhabited the northern parts of modern Germany since classical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Möller Stomo 3
The Möller Stomo 3 was a small, low-powered but very aerodynamically-clean light aircraft, first flown in Germany in 1939. It set two speed over distance records for aircraft with engines of less than capacity soon after its first flight. Design By early 1939 H.G. Möller Flugzeugbau had tested a small, single seat, cantilever, inverted gull wing sports aircraft of striking aerodynamic cleanliness. Though its Kroeber M4 flat twin engine produced only , the Stomo-3 had a maximum speed of . At the same time the company was completing a smaller span single-seater in the same clean style but with a Zündapp 9-092 four cylinder air-cooled, inverted inline engine labelled V11 ''Stürmer''. The Stomo 3 was an all wood aircraft, designed to be simple to build without specialist tools and to have low capital and running costs, together with good performance and aerobatic capability. Its low wing was in three parts: a centre section with anhedral, improving the wing root aerodyna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITS-8
The ITS-8 was a Polish twin-boom motor glider flown in 1936. Two prototypes were completed but production was prevented by the German invasion of Poland in 1939. Design and development In the mid-1930s there was growing Polish interest in low cost powered gliders and other small, low powered, structurally simple aircraft. The Institute of Gliding Techniques at Lwów University studied motor gliders, guided by Fédération Aéronautique Internationale, FAI specifications for the new International Powered Glider Class. They concluded that a conventional glider nose and forward fuselage was required, hence a pusher configuration, pusher engine and, to avoid the drag of a pylon engine mounting, a twin-boom layout. The ITS-8, designed to have a gliding performance competitive with contemporary intermediate and high performance unpowered machines, followed these specifications. Its construction was funded by the LOPP The wooden ITS-8 had a high wing which was built around a single spar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
