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 ...

Saab JAS 39 Gripen
The Saab JAS 39 Gripen (; English: ''griffin'') is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace and defense company Saab AB. The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. Later aircraft are fully NATO interoperable. , more than 271 Gripens of all models, A–F, have been built. In 1979, the Swedish government began development studies for "an aircraft for fighter, attack, and reconnaissance" (''ett jakt-, attack- och spaningsflygplan'', hence "JAS") to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force. A new design from Saab was selected and developed as the JAS 39. The first flight occurred in 1988, with delivery of the first serial production airplane in 1993. It entered service with the Swedish Air Force in 1996. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, began entering service in 2003. To marke ...

Canard (aeronautics)
In aeronautics, a canard is a wing configuration in which a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.. Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck (''canard'' in French) with its neck stretched out in flight. Despite the use of a canard surface on the first powered aeroplane, the Wright Flyer of 1903, canard designs were not built in quantity until the appearance of the Saab Viggen jet fighter in 1967. The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to ...

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. The Saab 35 Draken is known for, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab AB
Saab AB (originally , later just SAAB and Saab Group) is a Swedish aerospace and defence company, founded in 1937. Headquartered in Stockholm, the development and the manufacturing is undertaken in Linköping. Saab produced automobiles from 1947 until 1990 when the automobile division was spun off as Saab Automobile, a joint venture with General Motors. The joint venture ended in 2000 when GM took complete ownership. From 1968 onwards the company was in a merger with commercial vehicle manufacturer Scania-Vabis, known as Saab-Scania. The two were de-merged in 1995 by the new owners, Investor AB. Despite the demerger, both Saab and Scania share the right to use the griffin logo, which originates from the coat of arms of the Swedish region of Scania. History "Svenska Aeroplan AktieBolag" (Swedish for "Swedish Aeroplane Company Limited") (SAAB) was founded in 1937 in Trollhättan, with the merger of Svenska Aero AB (SAAB) and Linköping based ASJA the headquarters move ...

Delta Wing
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ). Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed subsonic and supersonic flight. At the other end of the speed scale, the Rogallo flexible wing proved a practical design for the hang glider and other ultralight aircraft. The delta wing form has unique aerodynamic characteristics and structural advantages. Many design variations have evolved over the years, with and without additional stabilising surfaces. General characteristics Structure The long root chord of the delta wing and minimal structure outboard make it structurally efficient. It can be built stronger, stiffer and at the same time lighter than a swept wing of equivalent lifting capability. Because of this it is easy and relatively inexpensive to build – a substantial factor in the success of the M ... [...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 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] |
Swedish Air Force
The Swedish Air Force ( sv, Svenska flygvapnet or just ) is the air force branch of the Swedish Armed Forces. History The Swedish Air Force was created on 1 July, 1926 when the aircraft units of the Army and Navy were merged. Because of the escalating international tension during the 1930s the Air Force was reorganized and expanded from four to seven squadrons. World War II When World War II broke out in 1939 further expansion was initiated and this substantial expansion was not finished until the end of the war. Although Sweden never entered the war, a large air force was considered necessary to ward off the threat of invasion and to resist pressure through military threats from the great powers. By 1945 the Swedish Air Force had over 800 combat-ready aircraft, including 15 fighter divisions. A major problem for the Swedish Air Force during World War II was the lack of fuel. Sweden was surrounded by countries at war and could not rely on imported oil. Instead domestic oi ... [...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.

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] |
