Saab 37 Viggen
The Saab 37 Viggen (Swedish for ''"the Bolt"'' or ''"the Tufted Duck"'' ( see name)) is a retired Swedish single-seat, single-engine, short-medium range combat aircraft. Development work on the type was initiated at Saab in 1952 and, following the selection of a radical delta wing configuration, the resulting aircraft performed its first flight on 8 February 1967 and entered service in 21 June 1971. It was the first canard design produced in quantity.Fredriksen 2001, p. 279. The Viggen was also the most advanced fighter jet in Europe, albeit slower than the earlier MiG-21bis, until the introduction of the Panavia Tornado into operational service in 1981. Several distinct variants of the Viggen were produced to perform the roles of strike fighter (AJ 37), aerial reconnaissance (SF 37), maritime patrol aircraft (SH 37) and a two-seat trainer (Sk 37). In the late 1970s, the all-weather fighter-interceptor aircraft JA 37 variant was introduced. In November 2005, the Viggen was r ...

Maritime Patrol Aircraft
A maritime patrol aircraft (MPA), also known as a patrol aircraft, maritime reconnaissance aircraft, or by the older American term patrol bomber, is a fixed-wing aircraft designed to operate for long durations over water in maritime patrol roles — in particular anti-submarine warfare (ASW), anti-ship warfare (AShW), and search and rescue (SAR). Among other maritime surveillance resources, such as satellites, ships, unmanned aerial vehicles (UAVs) and helicopters, the MPA is an important asset. To perform ASW operations, MPAs typically carry air-deployable sonar buoys as well as torpedoes and are usually capable of extended flight at low altitudes. History First World War The first aircraft that would now be identified as maritime patrol aircraft were flown by the Royal Naval Air Service and the French Aéronautique Maritime during the First World War, primarily on anti-submarine patrols. France, Italy and Austria-Hungary used large numbers of smaller patrol aircraft for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aarne Lakomaa
Aarne Lakomaa (1914–2001) was a Finnish aircraft designer. Born in Finland, Lakomaa graduated from Helsinki Polytechnics. He fought as an Army Lieutenant in the Winter War (1939–40) and the Continuation War (1941–44) against the Soviet Union. There he became famous for fitting captured Russian engines to the obsolete French fighter Morane-Saulnier M.S.406, thereby creating a first rate fighter, the Mörkö-Morane ("mörkö" being Finnish roughly for "bogeyman" or "hobgoblin"). Aarne Lakomaa first replaced the original Hispano-Suiza 12Y 31 liquid-cooled V-12 rated at 860 hp with a 1,100 hp Soviet engine— the Klimov M-105P—which was a war booty.The Axis Air Forces: Flying in Support of the German Luftwaffe Retrieved 8 January 2018.

Saab 35 Draken
The Saab 35 Draken (; 'The Kite' or 'The Dragon') is a Swedish fighter-interceptor developed and manufactured by Svenska Aeroplan Aktiebolaget (SAAB) between 1955 and 1974. Development of the Saab 35 Draken started in 1948 as the Swedish air force future replacement for the then also in development Saab 29 Tunnan dayfighter and Saab 32B Lansen night fighter. It featured an innovative but unproven double delta wing, which led to the creation of a sub-scale test aircraft, the Saab 210, which was produced and flown to test this previously-unexplored aerodynamic feature. The full-scale production version entered service with frontline squadrons of the Swedish Air Force on 8 March 1960. It received the designation Flygplan 35 (Fpl 35; 'Aeroplane 35') and was produced in several variants and types, most commonly as a fighter type with the prefix ''J'' (J 35), standing for ''Jaktflygplan'' (Pursuit-aircraft), the Swedish term for fighter aircraft.

Saab 32 Lansen
The Saab 32 Lansen (English: Lance) is a two-seat, transonic military aircraft designed and manufactured by Saab AB from 1955 to 1960 for the Swedish Air Force (''Flygvapnet''). Three principal variants of the Lansen were built for attack (A 32A), fighter (J 32B), and reconnaissance (S 32C). During its long operational life, the Saab 32 also served in the electronic warfare role and as a target-tug. Development In Autumn 1946, the Saab company began internal studies aimed at developing a replacement aircraft for the Saab B 18/S 18 as Sweden's standard attack aircraft.''Saab'' 30 December 1960. p. 1017. In 1948, Saab was formally approached by the Swedish Government with a request to investigate the development of a turbojet-powered strike aircraft to replace a series of 1940s vintage attack, reconnaissance and night-fighter aircraft then in the Flygvapnet: the B 18/S 18, J 21R/A 21R and J 30 (de Havilland Mosquito). Out of several differing design studies performed, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tufted Duck
The tufted duck or tufted pochard (''Aythya fuligula'') is a small diving duck with a population of close to one million birds, found in northern Eurasia. The scientific name is derived from Ancient Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and ''Latin'' ''fuligo'' "soot" and ''gula'' "throat". Description The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks. In particular, some have white around the bill base which resembles the scaup species, although the white is never as extensive as in those ducks. The females' call is a harsh, growling "karr", mostly given in flight. The males are mostly silent but they make whistles during courtship based on a simple "wit-oo". The onl ...

Prefix
A prefix is an affix which is placed before the Word stem, stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix ''un-'' is added to the word ''happy'', it creates the word ''unhappy''. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed. Prefixes, like other affixes, can be either inflectional, creating a new form of the word with the same basic meaning and same part of speech, lexical category (but playing a different role in the sentence), or Morphological derivation, derivational, creating a new word with a new semantics, semantic meaning and sometimes also a different Part of speech, lexical category. Prefixes, like all other affixes, are usually Bound and unbound morphemes, bound morphemes. In English language, English, there are no inflectional prefixes; English uses suffixes instead for that purpose. The word ''prefix'' ...

Mjölnir
Mjölnir (from Old Norse Mjǫllnir) is the hammer of the thunder god Thor in Norse mythology, used both as a devastating weapon and as a divine instrument to provide blessings. The hammer is attested in numerous sources, including the 11th century runic Kvinneby amulet, the ''Poetic Edda'', a collection of eddic poetry compiled in the 13th century, and the ''Prose Edda'', a collection of prose and poetry compiled in the 13th century. The hammer was commonly worn as a pendant during the Viking Age in the Scandinavian cultural sphere, and Thor and his hammer occur depicted on a variety of objects from the archaeological record. Today the symbol appears in a wide variety of media and is again worn as a pendant by various groups, including adherents of modern Heathenry. Etymology The etymology of the hammer's name, ''Mjǫllnir'', is disputed among historical linguists. Old Norse ''Mjǫllnir'' developed from Proto-Norse *''melluniaR'' and one proposed derivation connects this form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Viking Age
The Viking Age () was the period during the Middle Ages when Norsemen known as Vikings undertook large-scale raiding, colonizing, conquest, and trading throughout Europe and reached North America. It followed the Migration Period and the Germanic Iron Age. The Viking Age applies not only to their homeland of Scandinavia but also to any place significantly settled by Scandinavians during the period. The Scandinavians of the Viking Age are often referred to as ''Vikings'' as well as ''Norsemen'', although few of them were Vikings in sense of being engaged in piracy. Voyaging by sea from their homelands in Denmark, Norway, and Sweden, the Norse people settled in the British Isles, Ireland, the Faroe Islands, Iceland, Greenland, Normandy, and the Baltic coast and along the Dnieper and Volga trade routes in eastern Europe, where they were also known as Varangians. They also briefly settled in Newfoundland, becoming the first Europeans to reach North America. The Norse-Gaels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thunderstone (folklore)
A thunderstone is a prehistoric hand axe, stone tool, or fossil which was used as an amulet to protect a person or a building. The name derives from the ancient belief that the object was found at a place where lightning had struck. Thunderstone folklore European tradition Albanians believed in the supreme powers of thunder-stones (''kokrra e rrufesë'' or ''guri i rejës''), which were believed to be formed during lightning strikes and to be fallen from the sky. Thunder-stones were preserved in family life as important cult objects. It was believed that bringing them inside the house could bring good fortune, prosperity and progress in people, in livestock and in agriculture, or that rifle bullets would not hit the owners of the thunder-stones. A common practice was to hang a thunder-stone pendant on the body of the cattle or on the pregnant woman for good luck and to contrast the evil eye.
