Saab 29 Tunnan
The Saab 29 ''Tunnan'' (''The Barrel''), colloquially also ''Flygande Tunnan'' (''The Flying Barrel''), is an early jet-powered fighter aircraft designed and produced by the Swedish aircraft manufacturer Saab. It was the second turbojet-powered combat aircraft to be developed in Sweden, the first being the Saab 21R, and it was the first Western European fighter to be produced with a swept wing after the Second World War, only being preceded in Western Europe as a whole by the Messerschmitt Me 262 built during the conflict.Boyne 2002, p. 547."1940s." ''Saab'', Retrieved: 27 March 2016. Work on what would become the Tunnan commenced in late 1945. The design, internally designated ''R 1001'', had a barrel-like fuselage, giving it a destinctive rotund appearance, from which its name is derived. A relatively thin swept wing configur ...

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed ''Schwalbe'' (German: "Swallow") in fighter versions, or ''Sturmvogel'' (German: "Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational jet-powered fighter aircraft. The initial design of what would become the Me 262 started in April 1939, prior to the start of the Second World War. While the aircraft performed its maiden flight on 18 April 1941, this was using piston engine instead of jet propulsion; it was not until 18 July 1942 that the first jet-powered flight was performed. Progress on the project was delayed by problems with engines, metallurgy and top-level interference from figures such as Hermann Göring, head of the Luftwaffe, and Adolf Hitler. The latter advocated from the Me 262 to be operated as a ground-attack/bomber aircraft rather than a defensive interceptor, thus necessitating a ...

Frid Wänström
''Frid'' Benjamin Filippus Wänström (May 8, 1905, Lidköping – September 11, 1988, Linköping) was a Swedish aviation engineer who after KTH Royal Institute of Technology in 1932 was employed by the flygstyrelsen (predecessor to Royal Swedish Air Force Materiel Administration), from 1936 head of the calculation department Saab AB in Linköping. Frid Wänström is mentioned for leading the work with Saab 29 Tunnan. It was the first fighter aircraft in Sweden with Swept wing. Information about arrow wings came from Switzerland and should have included drawings on Messerschmitts Me P1101, P1110, P1111 and P1112. SAAB:s project manager Frid Wänström fetched these secret papers from Switzerland to Sweden in 1945. The documents came from engineers from Messerschmitt who moved to Switzerland at the end of World War II. Frid Wänström also participated in the following Saab projects Saab 32 Lansen, Saab 35 Draken and Saab 37 Viggen The Saab 37 Viggen ( Swedish for ''"the ...

Messerschmitt P
Messerschmitt AG () was a German share-ownership limited, aircraft manufacturing corporation named after its chief designer Willy Messerschmitt from mid-July 1938 onwards, and known primarily for its World War II fighter aircraft, in particular the Bf 109 and Me 262. The company survived in the post-war era, undergoing a number of mergers and changing its name from Messerschmitt to Messerschmitt-Bölkow-Blohm before being bought by Deutsche Aerospace (DASA, now part of Airbus) in 1989. History Background In February 1916, the south German engineering company MAN AG and several banks purchased the unprofitable aircraft builder Otto-Flugzeugwerke, starting a new company, ''Bayerische Flugzeugwerke AG'' (abbreviated ''B.F.W.''). The articles of association were drawn up on 19 and 20 February, and completed on 2 March 1916. Details of the company were recorded in the Commercial Register with an equity capital of RM 1,000,000 on 7 March 1916. 36% of the capital was provided ...

Barrel (storage)
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg. Modern wooden barrels for wine-making are made of French common oak (''Quercus robur''), white oak (''Quercus petraea''), American white oak (''Quercus alba''), more exotic is Mizunara Oak all typically have standard sizes: Recently Oregon Oak (Quercus Garryana) has been used. *"Bordeaux type" , *"Burgundy type" and *"Cognac type" . Modern barrels and casks can also be made of aluminum, stainless steel, and different types of plastic, such as HDPE. Someone who makes barrels is called a "barrel maker" or cooper (coopers also make buckets, vats, tubs, butter churns, hogsheads, firkins, kegs, kilderkins, tierces, rundlets, puncheons, pipes, tuns, butts, pins, tr ...

Lockheed P-80 Shooting Star
The Lockheed P-80 Shooting Star was the first Jet aircraft, jet fighter aircraft, fighter used operationally by the United States Army Air Forces (USAAF) during World War II. Designed and built by Lockheed Corporation, Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80. America's first successful turbojet-powered combat aircraft, it was soon outclassed with the appearance of the swept-wing transonic MiG-15 and was quickly replaced in the air superiority role by the transonic F-86 Sabre. The F-94 Starfire, an all-weather interceptor using the same airframe, also saw Korean War service. The closely related Lockheed T-33, T-33 Shooting Star Trainer (aircraft), trainer remained in service with the U.S. Air For ...

Fighter-bomber
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles. Although still used, the term fighter-bomber has less significance since the introduction of rockets and guided missiles into aerial warfare. Modern aircraft with similar duties are now typically called multirole combat aircraft or strike fighters. Development Prior to World War II, general limitations in available engine and aeronautical technology required that each proposed military aircraft have its design tailored to a specific prescribed role. Reciprocating engine, Engine power grew dramatically during the early period of the war, roughly doubling between 1939 and 1943. The Bristol Blenheim, a typical light bomber A light bomber is a r ...

ONUC
The United Nations Operation in the Congo (french: Opération des Nations Unies au Congo, abbreviated to ONUC) was a United Nations peacekeeping force deployed in the Republic of the Congo in 1960 in response to the Congo Crisis. ONUC was the UN's first peacekeeping mission with significant military capabilities, and remains one of the largest UN operations in both scale and operational scope. Following its independence from Belgium on 30 June 1960, the Congo descended into chaos and disorder, prompting its former colonial power to invade under the pretext of restoring law and order and protecting Belgian nationals. On 12 July 1960, the Congolese Government appealed to the UN for assistance, and on 14 July 1960 the United Nations Security Council passed Resolution 143 (S/4387) calling upon Belgium to withdraw its troops, and authorizing the Secretary-General to provide the Congolese Government with military assistance, as the Force Publique was not in a condition to meet its ...

Republic Of The Congo (Léopoldville)
The Republic of the Congo (french: République du Congo) was a sovereign state in Central Africa, created with the independence of the Belgian Congo in 1960. From 1960 to 1966, the country was also known as Congo-Léopoldville (after its capital) to distinguish it from its northwestern neighbor, which is also called the Republic of the Congo, alternatively known as "Congo-Brazzaville". In 1964, the state's official name was changed to the ''Democratic Republic of the Congo,''"Zaire: Post-Independence Political Development" ''Library of Congress'' but the two countries continued to be distinguished by their capitals; with the renaming of Léopoldville as Kinshasa in 1966, it became also known as Congo-Kinshasa. After Joseph Désiré Mobutu, renamed Mobutu Sese Seko in 1972, com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Reconnaissance
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers. History Early developments After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon ''L'Entreprenant'', the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisatio ...

Afterburner
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process injects additional fuel into a combustor in the jet pipe behind (''i.e.'', "after") the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its attendant weight penalty, but at the cost of increased fuel consumption (decreased fuel efficiency) which limits its use to short periods. This aircraft application of "reheat" contrasts with the meaning and implementation of "reheat" applicable to gas turbines driving electrical generators and which reduces fuel consumption. Jet engines are referred to as operating ''wet'' when afterburning and ''dry'' when not. An engine producing maximum thrust wet is at ''maximum power,'' while an engine ...
