Messerschmitt Me 323
The Messerschmitt Me 323 ''Gigant'' ("Giant") was a German military transport aircraft of World War II. It was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft to fly during the war. A total of 213 were made, 15 being converted from the Me 321. Development The Me 323 was the result of a 1940 German requirement for a large assault glider in preparation for Operation Sea Lion, the projected invasion of Great Britain. The DFS 230 light glider had already proven its worth in the Battle of Fort Eben-Emael in Belgium (the first ever assault by gliderborne troops), and would later be used successfully in the invasion of Crete in 1941. However, in order to mount an invasion across the English Channel, the Germans would need to be able to airlift vehicles and other heavy equipment as part of an initial assault wave. Although Operation Sea Lion was cancelled, the requirement for a heavy air transport capability still existed, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operation Barbarossa
Operation Barbarossa (german: link=no, Unternehmen Barbarossa; ) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. The operation, code-named after Frederick Barbarossa ("red beard"), a 12th-century Holy Roman emperor and German king, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories. Their ultimate goal was to create more (living space) for Germany, and the eventual extermination of the indigenous Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. In the two years leading up to the invasion, Nazi Germany and the Soviet Union signed political and economic pacts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers Ju 52
The Junkers Ju 52/3m (nicknamed ''Tante Ju'' ("Aunt Ju") and ''Iron Annie'') is a transport aircraft that was designed and manufactured by German aviation company Junkers. Development of the Ju 52 commenced during 1930, headed by German aeronautical engineer Ernst Zindel. The aircraft's design incorporated a corrugated duralumin metal skin as a strengthening measure, which was very unusual at the time. The Ju 52's maiden flight was performed on 13 October 1930. It was initially designed with a single engine, however, it was produced in quantity as a trimotor. The primary early production model, the ''Ju 52/3m'', was principally operated as a 17-seat airliner or utility transport aircraft by various civil operators during the 1930s. Following the rise of Nazi Germany, thousands of Ju 52s were procured as a staple military transport of the nation. The ''Ju 52/3mg7e'' was the principal production model. The Ju 52 was in production between 1931 and 1952. In a civilian role, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be ...

Gnome Et Rhône
Gnome et Rhône was a major French aircraft engine manufacturer. Between 1914 and 1918 they produced 25,000 of their 9-cylinder Delta and Le Rhône 110 hp (81 kW) rotary designs, while another 75,000 were produced by various licensees. These engines powered the majority of aircraft in the first half of the war, both Allied designs as well as German examples produced by Motorenfabrik Oberursel. In the post-war era they started a new design series originally based on the Bristol Jupiter, but evolving into the excellent twin-row, 1,000 hp-class (750 kW) Gnome-Rhône 14K ''Mistral Major'' radial, which was likewise licensed and used around the world during World War II. They were a major supplier of engines to the German ''Luftwaffe'', producing both their own designs as well as German ones under licence. Their factories were the target of highly accurate bombing, knocking them out of the war. The company was nationalized as a part of Snecma in 1949, but ...

Messerschmitt Me 263
The Messerschmitt Me 263 ''Scholle'' (plaice)Christopher 2013, p. 142. was a rocket-powered fighter aircraft developed from the Messerschmitt Me 163 Komet, Me 163 ''Komet'' towards the end of World War II. Three prototypes were built but never flown under their own power as the rapidly deteriorating military situation in Germany prevented the completion of the test program. History Although the Me 163 had very short endurance, it had originally been even shorter. In the first design, the rocket had no throttle and burned through its fuel in a few minutes. Not only did this sharply limit endurance, during flight testing pilots found the aircraft quickly exhibited compressibility effects as they levelled out from the climb and the speed picked up. This led the Reichsluftfahrtministerium, ''RLM'' to demand the addition of a throttle, leading to lengthy delays but a dramatic increase in fuel economy in automobiles, fuel economy when throttled. This problem was addressed in the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messerschmitt Me 261
The Messerschmitt Me 261 ''Adolfine'' was a long- range reconnaissance aircraft designed in the late 1930s. It looked like an enlarged version of the Messerschmitt Bf 110. It was not put into production; just three Me 261s were built and used primarily for testing and development purposes. Design and development In 1937, Messerschmitt began ''Projekt'' P. 1064, a study for a long-range reconnaissance aircraft, and took the design of the Bf 110 twin-engine heavy fighter (and derivative Bf 161 reconnaissance / Bf 162 light bomber projects) as its basis. The P. 1064 had a long, slim fuselage with two wing-mounted engines. The aircraft was planned from the outset as a record-breaking aircraft, but after becoming convinced that the aircraft was capable of taking the world long-distance flight record, the German Air Ministry (''Reichsluftfahrtministerium'') approved the project and gave it the airframe designation number of 8-261.Green 1970, p. 617. The intended goal of the project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Junkers Ju 322
The Junkers Ju 322 ''Mammut'' (German for mammoth) was a heavy transport military glider, resembling a giant flying wing, proposed for use by the ''Luftwaffe'' in World War II; only two prototypes were completed, a further 98 were scrapped before completion. Development Designed in late 1940 by Junkers as the Junkers EF 094, the Ju 322 was to fulfill the same role as the Me 321 ''Gigant'' heavy transport glider. Fulfilling a requirement to be built out of non-strategic materials, using all-wooden construction, the Ju322 was to be able to carry of cargo, equivalent to either a Panzer IV tank, a 88mm anti-aircraft gun, a half-track or a self propelled gun, including attendant personnel, ammunition and fuel. The cargo door was located in the centre section of the leading edge of the wing, with the cockpit offset to the port side above the cargo bay. The glider's tailplane extended from the centre section, and had a typical arrangement of stabilizing fins and vertical rudder. Armam ...

Medium Tank
A medium tank is a classification of tanks, particularly prevalent during World War II which represented a compromise between the mobility oriented light tanks and the armour and armament oriented heavy tanks. A medium tank's classification is not actually based on weight, but off of tactical usage and intended purpose; for instance the German Panzerkampfwagen V Panther medium tank has a mass similar to contemporary Allied heavy tanks. The most widely produced, cost effective and successful tanks of World War II (the German Panzer IV, the Soviet T-34, and the American M4 Sherman) were all medium tank designs. Many of the medium tank lines became what are called main battle tanks in most countries. History The first tanks to carry the name "Medium" appeared in the First World War with the British Medium Mark A Whippet. It was smaller, lighter and faster than the British heavy tanks of the time and only carried machine guns. The medium tank doctrine came into use in the inter ...

Panzer IV
The ''Panzerkampfwagen'' IV (Pz.Kpfw. IV), commonly known as the ''Panzer'' IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161. The Panzer IV was the most numerous German tank and the second-most numerous German fully tracked armoured fighting vehicle of the Second World War; 8,553 Panzer IVs of all versions were built during World War II, only exceeded by the StuG III assault gun with 10,086 vehicles. Its chassis was also used as the base for many other fighting vehicles, including the Sturmgeschütz IV assault gun, the Jagdpanzer IV self-propelled anti-tank gun, the '' Wirbelwind'' self-propelled anti-aircraft gun, and the '' Brummbär'' self-propelled gun. The Panzer IV saw service in all combat theatres involving Germany and was the only German tank to remain in continuous production throughout the war. It was originally designed for infantry support, while the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
