Lille 6As
The Jumo 205 aircraft engine was the most numerous 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 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 ports w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airliner
An airliner is a type of airplane for transporting passengers and air cargo. Such aircraft are most often operated by airlines. The modern and most common variant of the airliner is a long, tube shaped, and jet powered aircraft. 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 carriers, legacy carriers, and flag carriers, and are used to feed traffic into the large a ...

BV 138
The Blohm & Voss BV 138 ''Seedrache'' (Sea Dragon) was a trimotor flying boat designed and built by the German aircraft manufacturer Blohm & Voss. It served as the ''Luftwaffe''s primary seaborne long-range maritime patrol and naval reconnaissance aircraft operated by the ''Luftwaffe'' during the Second World War. The BV 138 was a pre-war design by Dr Richard Vogt, originally developed under the company name of Hamburger Flugzeugbau, and thus it was initially designated ''Ha 138'' instead. It had an uncommon appearance due to its combination of unusual design features, such as its twin boom tail unit, short hull, and trimotor engine configuration. In reference to the side-view shape of its fuselage, the aircraft was often referred to via the nickname ''Der Fliegende Holzschuh'' ("Flying Clog").Nowarra 1997, original German title of the Schiffer book. Originally designed to be powered using two engines, the trimotor configuration was adopted prior to flight testing due to engin ...

Maritime Patrol
Maritime patrol or maritime reconnaissance 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 used. Typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blohm & Voss Ha 139
The Blohm & Voss Ha 139 was a four-engined, all-metal, inverted gull wing floatplane, designed and built by the Nazi Germany, German aircraft manufacturer Blohm & Voss (aircraft), Blohm & Voss. At the time of the first aircraft's completion, it was one of the largest float-equipped seaplanes to have been built. Development of the Ha 139 started in 1935 to fulfil a specification issued by the German flag carrier ''Deutsche Luft Hansa''. Built to serve on the airline's long distance routes, it was equipped with four hydraulically-actuated landing Flap (aeronautics), flaps, was powered by four Junkers Jumo 205C diesel engines, and was suitable for Assisted take-off#Catapults (CATO), catapult-assisted takeoffs. The Ha 139A was promptly followed by the Ha 139B, a variant that possessed greater size and weight. Development of the aircraft led to a land-based version, the Blohm & Voss BV 142 and a proposed reconnaissance/bomber variant of the Ha 139 for the ''Luftwaffe'' was never reali ...

Airship
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying powered aircraft, under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift (physics), lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used thermal airship, hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a 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). Introduction Diesel engines work by compressing only air, or air combined with 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 air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, 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.

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 prototyping, 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. Physical prototyping has a long history, and paper prototyping and virtual prototyping now extensively complement it. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, 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 ...

Bernard 82
The Bernard 82 was a French single-engined long-range monoplane bomber designed and built by Société des Avions Bernard. Only two prototypes were built and the type did not enter production. 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. It was fitted with a relatively large wing, a complex retractable landing gear mechanism, and powered by a single nose-mounted Hispano-Suiza 12Ybrs inline piston engine. A total of two prototypes were produced; the first made its maiden flight in December 1933 while the second prototype followed during March 1934.NACA 1934, p. 1. Flight testing revealed the landing gear retraction system to be unreliable, forcing more than one belly landing to be performed as a result. Reliable operation was never achieved as testing was wound dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peugeot
Peugeot (, , ) is a French automobile brand owned by Stellantis. The family business that preceded the current Peugeot companies was established in 1810, making it the oldest car company in the world. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first vehicle, a Steam car, steam-powered tricycle. In 1886, the company collaborated with Léon Serpollet, followed by the development of an internal combustion car in 1890, which used a Panhard-Daimler-Motoren-Gesellschaft, Daimler engine. The Peugeot family and company are originally from Sochaux, where Peugeot still operates a large manufacturing facility and the Musée de l'Aventure Peugeot, Peugeot Museum. Peugeot vehicles have received numerous international accolades, including six European Car of the Year awards. The brand also boasts over a century of success in motorsport, with victories including the Indianapolis 500 in 1913, 1916, and 1919. Peugeot Spo ...

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. It is rumoured to have been taken to Moscow at the end of World War II, where development may have continued. Jumo 224 In 1942 the 223 was abandoned in favour of an even larger engine, the Jumo 224 with an intended output power of 4,500 horsepower. The Jumo 223 series was influential to the successful three-crankshaft Napier Deltic The Napier Deltic engine is a British opposed-piston valveless, supercharged uniflow scavenged, two-stroke diesel engine used in marine and locomotive applications, d ...
