IVL C.25
IVL C.VI.25 was a Finnish fighter aircraft designed by IVL. It was a further development of the IVL C.24. The aircraft made its maiden flight on June 11, 1925. The aircraft was wrecked after a forced landing, due to engine trouble, on December 17, 1925. The aircraft was under-powered, like its predecessor, and it was not considered possible to further develop the aircraft.

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".

Ilmailuvoimien Lentokonetehdas
''Valtion lentokonetehdas'' (State aircraft factory) was a Finnish aircraft manufacturing company that was founded on 23 February 1928 from the IVL or I.V.L. factory (Ilmailuvoimien lentokonetehdas, Finnish Air Force Aircraft Factory), founded in 1921. The company was transferred from being subordinate to the Finnish Air Force to being subordinate to the Ministry of Defence. The company, and its products were named with the prefix VL. Island factory The company began its production at Suomenlinna and Santahamina in Helsinki. The factory did not have an airport, only the sea and sea ice could be used for take-off and landing. Most of the aircraft built in Helsinki were seaplanes. In Helsinki the aircraft built were small compared to the Bristol Blenheim bombers built under licence in the late 1930s. Much of the final assembly was done outdoors. The company was looking for a new production facility further away from the Soviet Union. Helsinki was seen as a bad location for an arm ...

Finnish Air Force
The Finnish Air Force (FAF or FiAF; fi, Ilmavoimat, , Air forces; sv, Flygvapnet, , Air weapon) is one of the branches of the Finnish Defence Forces. Its peacetime tasks are airspace surveillance, identification flights, and production of Finnish Rapid Deployment Force, readiness formations for wartime conditions. The Finnish Air Force was founded on 6 March 1918. History The Finnish Air Force, one of the oldest air forces of the world, pre-dates the British Royal Air Force, RAF (founded as an independent entity on 1 April 1918) and the Swedish (founded on 1 July 1926). The first steps in the history of Finnish aviation involved Russian Empire , Russian aircraft. The Russian military had a number of early designs stationed in the Grand Duchy of Finland, which until the Russian Revolution of 1917 formed part of the Russian Empire. Soon after the Finnish Declaration of Independence , Finnish declaration of independence of 6 December 1917, the Finnish Civil War of January to May ...

Finland
Finland ( fi, Suomi ; sv, Finland ), officially the Republic of Finland (; ), is a Nordic country in Northern Europe. It shares land borders with Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland across Estonia to the south. Finland covers an area of with a population of 5.6 million. Helsinki is the capital and largest city, forming a larger metropolitan area with the neighbouring cities of Espoo, Kauniainen, and Vantaa. The vast majority of the population are ethnic Finns. Finnish, alongside Swedish, are the official languages. Swedish is the native language of 5.2% of the population. Finland's climate varies from humid continental in the south to the boreal in the north. The land cover is primarily a boreal forest biome, with more than 180,000 recorded lakes. Finland was first inhabited around 9000 BC after the Last Glacial Period. The Stone Age introduced several differ ... [...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] |
Siemens-Halske Sh
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the openi ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...
