Junkers Ju 49
The Junkers Ju 49 was a German aircraft designed to investigate high-altitude flight and the techniques of cabin pressurization. It was the world's second working pressurized aircraft, following the Engineering Division USD-9A which first flew in the United States in 1921. By 1935, it was flying regularly to around 12,500 m (41,000 ft). Development The Junkers Ju 49 was developed entirely to investigate techniques for flight at high altitude. To this end, it had a specially developed engine and the first pressurized cabin in a German aircraft. The engine was the Junkers L88a, which combined two six-cylinder inline L8 motors into an upright V-12 and had a two-stage supercharger plus intercooler to sustain power at high altitudes. It produced 522 kW (700 hp) at about 5,800 m (19,000 ft). This engine drove a large four-blade propeller. The pressure cabin held the two crew. The original intention was for operation at about 6,000 m (20,000 ft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Caproni Ca
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950. Many of the company's former assets were subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol 138
The Bristol Type 138 High Altitude Monoplane was a British high-altitude single-engine, low-wing monoplane research aircraft developed and produced by the Bristol Aeroplane Company during the 1930s. It set nine world altitude records, with the maximum altitude achieved being on 30 June 1937, during a 2¼-hour flight. A second aircraft, designated as the Type 138B, was ordered in 1935 but work was abandoned during 1937 without it having flown. Development The Type 138 was built during a period of intense competition between aviation manufacturers. Prestige and useful technological progress came from breaking major aviation records, such as airspeed, distance and altitude but by the 1930s, the resources and development work necessary to achieve these records was beyond individual companies, and required government assistance.Barnes 1964, p. 253.

Lockheed Vega
The Lockheed Vega is an American five- to seven-seat high-wing monoplane airliner built by the Lockheed Corporation starting in 1927. It became famous for its use by a number of record-breaking pilots who were attracted to the rugged and very long-range design. Amelia Earhart became the first woman to fly solo across the Atlantic Ocean in one, and Wiley Post used his to prove the existence of the jet stream after having flown around the world twice. Design and development Designed by John Knudsen Northrop and Gerald Vultee, both of whom would later form their own companies, the aircraft was originally intended to serve with Lockheed's own airline routes. They set out to build a four-passenger (plus pilot) aircraft that was not only rugged but also one of the fastest aircraft of its era. Using a wooden monocoque fuselage, plywood-covered cantilever wings and the best engine available, the Vega delivered on the promise of speed. The fuselage was built from sheets of plywood, ski ...

Wiley Post
Wiley Hardeman Post (November 22, 1898 – August 15, 1935) was a famed American aviator during the interwar period and the first pilot to fly solo around the world. Also known for his work in high-altitude flying, Post helped develop one of the first pressure suits and discovered the jet stream. On August 15, 1935, Post and American humorist Will Rogers were killed when Post's aircraft crashed on takeoff from a lagoon near Point Barrow in the Territory of Alaska. Post's Lockheed Vega aircraft, the ''Winnie Mae'', was on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center from 2003 to 2011. It is now featured in the "Time and Navigation" gallery on the second floor of the National Air and Space Museum in Washington, D.C. Early life Post was born to parents who cultivated cotton on a farm near Grand Saline, Texas. His father was William Francis and his mother was Mae Quinlan Post, a person of mixed Cherokee heritage. His family moved to Oklahoma whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11 attacks, September 11, 2001 attacks, all major airlines Airport_security_repercussions_due_to_the_September_11_attacks#Improved_security_on_aircraft, fortified their cockpits against access by aircraft hijacking, hijackers. Etymology The word cockpit seems to have been cockpit (sailing), used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore.

Vickers Vespa
The Vickers Vespa was a British army cooperation biplane designed and built by Vickers Limited in the 1920s. While not adopted by Britain's Royal Air Force, small numbers were bought by the Irish Free State and Bolivia, the latter of which used the type during the Chaco War. One modified Vespa was used to set a world altitude record of 43,976 ft (13,407 m) in September 1932. Design and development The Vespa was designed by Vickers as a private venture to meet the requirements of Air Ministry Specification 30/24, the first prototype, the Vespa I being flown in September 1925.Mason 1994, p.173. The Vespa, which was a single-engine biplane with a slim fuselage suspended between closely spaced and highly staggered two-bay wooden wings, was delivered for evaluation by the Royal Air Force, but crash landed owing to engine trouble on 24 June 1926 and was badly damaged.Andrews and Morgan 1988, p.200. It was then rebuilt with steel, fabric-covered wings as the Vespa II, but ... [...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 ...

Bomber
A bomber is a military combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry (such as bombs), launching aerial torpedo, torpedoes, or deploying air-launched cruise missiles. The first use of bombs dropped from an aircraft occurred in the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Second World War by all major airforces causing devastating damage to cities, towns, and rural areas. The first purpose built bombers were the Italy, Italian Caproni Ca 30 and United Kingdom, British Bristol T.B.8, both of 1913. Some bombers were decorated with nose art or victory markings. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure or reduci ...
