Heinkel HD 19
The Heinkel HD 19 W (or Svenska Aero J 4) was a biplane seaplane fighter developed by Ernst Heinkel Flugzeugwerke . Development The Heinkel HD 19 W was the only naval fighter to be delivered to the Svenska Flygvapnet. Formed in 1926, the Svenska Flygvapnet issued a requirement in 1927 for an aircraft to be used for the defense of coastal fortifications and ships of the Navy. The specification determined the engine (the Bristol Jupiter VI) and the configuration of the aircraft, which should have been a seaplane with boots. The aircraft was designated J 4 (the acronym J stands for the Swedish word "Jagt", fighter) and two aircraft were ordered by Heinkel in September 1927. Meanwhile, the Swedish branch of Heinkel, the Svenska Aero AB based in Lidingö (an island in the Stockholm archipelago), made an offer for the Swedish air force and in October 1928 an order was made for four additional aircraft (serial numbers 282-285). The first delivery took place in May 1929, the last one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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".

Saab Group
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 moved to Linkö ...

Ernst Heinkel
Dr. Ernst Heinkel (24 January 1888 – 30 January 1958) was a German aircraft designer, manufacturer, ''Wehrwirtschaftsführer'' in Nazi Germany, and member of the Nazi party. His company Heinkel Flugzeugwerke produced the Heinkel He 178, the world's first turbojet-powered aircraft, and the Heinkel He 176, the first rocket aircraft. Early life Heinkel was born in Grunbach, today a part of Remshalden. As a young man he became an apprentice machinist at a foundry. Heinkel studied at the Technical Academy of Stuttgart,"Who's who in Nazi Germany" Robert S. Wistrich. Routledge, 2001. , .

Svenska Flygvapnet
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 oil s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Jupiter VI
The Bristol Jupiter was a British nine-cylinder single-row piston radial engine built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era. The Jupiter was widely used on many aircraft designs during the 1920s and 1930s. Thousands of Jupiters of all versions were produced, both by Bristol and abroad under licence. A turbo-supercharged version of the Jupiter known as the Orion suffered development problems and only a small number were produced. The "Orion" name was later re-used by Bristol for an unrelated turboprop engine. Design and development The Jupiter was designed during World War I by Roy Fedden of Brazil Straker and later Cosmos Engineering. The first Jupiter was completed by Brazil Straker in 1918 and featured three carburettors, each one feeding three of the engine's nine cylinders via a spiral deflector housed ins ...

Heinkel Aircraft
Heinkel Flugzeugwerke () was a German aircraft manufacturing company founded by and named after Ernst Heinkel. It is noted for producing bomber aircraft for the Luftwaffe in World War II and for important contributions to high-speed flight, with the pioneering examples of a successful liquid-fueled rocket and a turbojet-powered aircraft in aviation history, with both Heinkel designs' first flights occurring shortly before the outbreak of World War II in Europe. History Following the successful career of Ernst Heinkel as the chief designer for the Hansa-Brandenburg aviation firm in World War I, Heinkel's own firm was established at Warnemünde in 1922, after the restrictions on German aviation imposed by the Treaty of Versailles were relaxed. By 1929, the firm's compressed air-powered catapults were in use on the German Norddeutscher Lloyd ocean-liners and to launch short-range mail planes from the liners' decks. The company's first post-World War I aircraft design success was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...
