SIG 33
The 15 cm sIG 33 (''schweres Infanterie Geschütz 33'', lit. "Heavy Infantry Gun") was the standard German heavy infantry gun used in the Second World War. It was the largest weapon ever classified as an infantry gun by any nation.Hogg, p. 26 Its weight made it difficult to use in the field, and the gun was increasingly adapted to various ''ad hoc'' mobile mountings. These were generically referred to as the SIG 33. Development Sources differ on the development history, but the gun itself was of conventional design. Early production models were horse-drawn, with wooden wheels. Later production models had pressed steel wheels, with solid rubber tires and air brakes for motor towing, albeit at a low speed (only carriages with pneumatic tires and suspension system could be towed at highway speeds). As with most German artillery carriages, the solid rubber tires and lack of springing meant that the gun could not safely be towed above 10 mph, and horse-drawing was still e ...

Air Brake (road Vehicle)
An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad or brake shoe needed to stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, such as trucks, buses, trailers, and semi-trailers, in addition to their use in railroad trains. George Westinghouse first developed air brakes for use in railway service. He patented a safer air brake on March 5, 1872. Westinghouse made numerous alterations to improve his air pressured brake invention, which led to various forms of the automatic brake. In the early 20th century, after its advantages were proven in railway use, it was adopted by manufacturers of trucks and heavy road vehicles. Design and function Air brakes are typically used on heavy trucks and buses. Typical operating pressure is approximatel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Artillery Of Germany
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trinitrotoluene
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive that i ...

Shaped Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significant ...

Amatol
Amatol is a highly explosive material made from a mixture of TNT and ammonium nitrate. The British name originates from the words ammonium and toluene (the precursor of TNT). Similar mixtures (one part dinitronaphthalene and seven parts ammonium nitrate) were known as Schneiderite in France. Amatol was used extensively during World War I and World War II, typically as an explosive in military weapons such as aircraft bombs, shells, depth charges, and naval mines.Brown, G. I. (1998). ''The Big Bang: A History of Explosives''. Sutton Publishing . pp. 158-163. It was eventually replaced with alternative explosives such as Composition B, Torpex, and Tritonal. Invention Following the Shell Crisis of 1915 in which the UK did not have enough ordnance due to a lack of explosives, a team at the Royal Arsenal laboratories produced a mixture of ammonium nitrate and TNT, known as Amatol for short. Special factories were constructed for the manufacture of ammonium nitrate by the double dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stielgranate 41
The Stielgranate 41 (German: "stick grenade"; model 1941) was a German shaped charge, fin-stabilized shell, used with the 3.7 cm Pak 36 anti-tank gun to give it better anti-tank performance. The 3.7 cm PaK-36, was the standard anti-tank gun of the Wehrmacht in 1940. During the battle of France in 1940 it had trouble dealing with thick armour of French and British tanks. In 1941, when Germany invaded the USSR, the gun was next to useless when confronted with Russian T-34 or KV-series tanks. It was successively replaced by larger calibre weapons, like the 5 cm PaK 38, but there were never enough of them, so it was decided to enhance the capability of the PaK 36 by providing it with new ammunition. The design looked like a rifle grenade, only considerably larger. One part of its stem, a stick, was placed inside the gun barrel; the other part, a perforated tube, fitted around it. On the tube there were six stabilizing fins. It was shot with a special blank cartridge at a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stielgranate 42
The Stielgranate 42 was a German fin-stabilized demolition charge, used with the 15 cm SIG 33 heavy infantry gun and armored vehicles armed with the SIG 33 during World War II. The primary purpose of the Stielgranate 42 was the demolition of concrete fortifications and for the clearing of minefields and barbed wire. Unlike the Stielgranate 41 it was not a shaped charge anti-tank weapon. In an emergency, the Stielgranate 42 could be used in an anti-tank role to great effect but due to its short range and poor accuracy the gun crew would be dangerously exposed to enemy fire. Design The Stielgranate 42 was of welded steel construction, consisting of three main parts: the nose cone, a cylindrical body, and a tapered tail with fins. Both the nose and the base of the projectile were reinforced with steel rings welded to the casing. The nose ring is threaded to accept a WgrZ.36 impact fuze also used by the leichter Ladungswerfer. A booster charge made up of compressed TNT pellet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Luftwaffe
The ''Luftwaffe'' () was the aerial-warfare branch of the German ''Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the ''Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabteilung'' of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the ''Luftwaffe''s existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a ''Luftwaffe'' detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing grou ...

Light Alloy
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and partic ...
