Lille 6Brs
The Jumo 205 aircraft engine was the most famous of a series of aircraft diesel engines produced by Junkers. The Jumo 204 first entered service in 1932. Later engines of this type comprised the experimental Jumo 206 and Jumo 208, with the Jumo 207 produced in some quantity for the Junkers Ju 86P and -R high-altitude reconnaissance aircraft, and the 46-meter wingspan, six-engined Blohm & Voss BV 222 ''Wiking'' flying boat. All three of these variants differed in stroke and bore and supercharging arrangements. In all, more than 900 of these engines were produced, in the 1930s and through most of World War II. Design and development These engines all used a two-stroke cycle with 12 pistons sharing six cylinders, piston crown to piston crown in an opposed configuration. This unusual configuration required two crankshafts, one at the bottom of the cylinder block and the other at the top, geared together. The pistons moved towards each other during the operating cycle. The intake ... [...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 Wikimedia project, 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 Magazine, 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".

Airliner
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BV 138
The Blohm & Voss BV 138 ''Seedrache'' (Sea Dragon), but nicknamed ''Der Fliegende Holzschuh'' ("flying clog",Nowarra 1997, original German title of the Schiffer book. from the side-view shape of its fuselage, as well as a play on the title of the Wagner opera 'Der Fliegende Hollander' or 'The Flying Dutchman') was a World War II German trimotor flying boat that served as the ''Luftwaffe''s main seaborne long-range maritime patrol and naval reconnaissance aircraft. A total of 297 BV 138s were built between 1938 and 1943. Design and development Originally developed under the company name of Hamburger Flugzeugbau, the type was initially designated the Ha 138. Its appearance was unique in its combination of unusual design features with its twin boom tail unit, short fuselage and trimotor engine configuration. The short hull, with its hydrodynamic step beneath and flat sides, earned it the nickname, "''Fliegender Holzschuh''" (the flying clog). The booms of the twin tail unit, ...

Maritime Patrol
{{Unreferenced, date=March 2008 Maritime patrol is the task of monitoring areas of water. Generally conducted by military and law enforcement agencies, maritime patrol is usually aimed at identifying human activities. Maritime patrol refers to active patrol of an area, as opposed to passive monitoring systems such as sound-detection fixtures or land-based spotters. A patrol consists of a ship, submarine, aircraft or satellite examining the patrolled area and seeking out activities to be identified and reported. Maritime patrol is critical in wartime situations for navies to locate enemy forces to engage or defend against. Peacetime patrols are important for interdiction of criminal activities and for ensuring legal use of waters. Maritime patrols can be conducted by surface ships and submarines, by aircraft (e.g. MPA) and other aerial vehicles, and even by satellites. Human spotting remains an important part of detecting activity, but increasingly electronic systems are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blohm & Voss Ha 139
The Blohm & Voss Ha 139 was a German all-metal inverted gull wing floatplane. With its four engines it was at the time one of the largest float-equipped seaplanes that had been built. The inboard engines were mounted at the joint between the inboard anhedral and outboard dihedral wing sections, above the pylon-mounted floats. Further development of the Ha 139 led to the land-based version Blohm & Voss BV 142 which had its first flight in October 1938. Operational history The aircraft were flown by ''Deutsche Luft Hansa'' on transatlantic routes between 1937 and 1939, predominantly between Bathurst, The Gambia and Natal, Brazil. Catapult-launched from an aircraft tender they were able to transport 500 kg of mail over a distance of up to 5,000 km. On the outbreak of World War II, the planes were transferred to the ''Luftwaffe'' and used for transport, reconnaissance and minesweeping work over the Baltic Sea. They were not particularly suited for military use. V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine ( gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''prototype'' derives from the Greek , "primitive form", neutral of , "original, primitive", from πρῶτ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernard 82
The Bernard 82 was a French single-engined long-range monoplane bomber designed and built by Société des Avions Bernard ''Société des Avions Bernard'' (french: Bernard Aircraft Company) was a French aircraft manufacturer of the early 20th century. History The company was founded in April 1917 by Adolphe Bernard as Etablissements Adolphe Bernard to licence-bu .... Only two prototypes were built and the type did not enter production. Design and development The Bernard 82 was developed from the long-range Bernard 80 GR, which had been designed to set long-distance-flight records. The all-metal Bernard 82 was a three-seat long-range bomber, known at the time as a ''bombardier de représailles'' or reprisal bomber. The cantilever mid-wing monoplane was powered by an Hispano-Suiza 12Ybrs inline piston engine. The first prototype flew from Le Bourget on 11 December 1933, and in March 1932 was joined by the second prototype. Flight testing showed the twin lateral radiators ...

Peugeot
Peugeot (, , ) is a French brand of automobiles owned by Stellantis. The family business that preceded the current Peugeot companies was founded in 1810, with a steel foundry that soon started making hand tools and kitchen equipment, and then bicycles. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first car steam tricycle, in collaboration with Léon Serpollet in 1889; this was followed in 1890 by an internal combustion car with a Panhard- Daimler engine. The Peugeot company and family are originally from Sochaux. Peugeot retains a large manufacturing plant and Peugeot museum there. In February 2014, the shareholders agreed to a recapitalisation plan for the PSA Group, in which Dongfeng Motors and the French government each bought a 14% stake in the company. Peugeot has received many international awards for its vehicles, including six European Car of the Year awards. Peugeot has been involved suc ...

Junkers Jumo 223
The Junkers Jumo 223 was an experimental 24-cylinder aircraft engine based on the Junkers Jumo 205. Like the Jumo 205, it was an opposed piston two-stroke diesel engine. It had four banks of six cylinders in a rhomboid configuration, with four crankshafts, one at each vertex of the rhombus, and 48 pistons. It was designed for a power of 2,500 horsepower at 4,400 rpm, and weighed around 2,370 kg.Gunston, p. 82 Only one example is known to have been built.
