Tellermine
The Teller mine () was a Germany, German-made antitank mine common in World War II. With explosives sealed inside a sheet metal casing and fitted with a pressure-actuated fuze, Teller mines had a built-in carrying handle on the side. As the name suggests (''Teller'' is the German word for dish or plate) the mines were plate-shaped. Design Containing little more than 5.5 kilograms of trinitrotoluene, TNT and a fuze activation pressure of approximately , the Teller mine was capable of blasting the tracks off any World War II-era tank or destroying a lightly armored vehicle. Due to its rather high operating pressure, only a vehicle or heavy object passing over the Teller mine would set it off. Of the two types of pressure-fuze available for Teller mines, the T.Mi.Z.43 fuze was notable for featuring an integral anti-handling device as standard: when the T.Mi.Z.43 fuze is inserted and the pressure plate (or screw cap) is screwed down into place, it shears a shear pin, weak arming ...

Tellermine 42
The Tellermine 42 (T.Mi.42) was a German metal-cased anti-tank mine, anti-tank blast mine used during the Second World War. The mine was a development of the Tellermine 35 with improved resistance to blast. It was followed by the simplified Tellermine 43. The Tellermine consists of a circular pressed steel main body with a large central pressure plate. The pressure plate is smaller than the earlier Tellermine 35, which increases the mine's resistance to blast. Two secondary fuze wells are provided for anti-handling devices, one in the side, and one on the bottom of the mine. The mine has a carrying handle. The T.Mi.Z.43 pressure fuze can be fitted to Tellermine 42s. The T.Mi.Z.43 fuze is notable for featuring an integral anti-handling device as standard: when the fuze is inserted and the pressure plate screwed down into place, it shears a weak arming pin in the fuze with an audible "snap". This action arms the anti-handling device. Thereafter, any attempt to disarm the mine by u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tellermine 43
The Tellermine 43 was a German circular steel-cased anti-tank blast mine used during the Second World War. It was a simplified version of the Tellermine 42, which enabled simpler production techniques. Between March 1943 and the end of World War II, Germany produced over 3.6 million Tellermine 43s. Several countries produced copies of the mine including Denmark (M/47), France (Model 1948) and Yugoslavia ( TMM-1). Finland used these mines with the designation PANSSARIMIINA m/43. Description The casing of the Teller mine is circular, rising toward the center with a large flat pressure plate. A rectangular metal carrying handle is fitted to the side of the mine. The pressure plate sits over the fuze well which can hold either a T.Mi.Z.42 shear pin fuze or T.Mi.Z.43 ball release fuze. The mine is armed by removing the pressure plate, screwing a fuze into the fuze well, then screwing the pressure plate back on again. At the bottom of the fuze well is a PETN booster charge, surround ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antitank Mine
An anti-tank or AT mine is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles. Compared to anti-personnel mines, anti-tank mines typically have a much larger explosive charge, and a fuze designed to be triggered by vehicles or, in some cases, remotely or by tampering with the mine. History First World War The first anti-tank mines were improvised during the First World War as a countermeasure against the first tanks introduced by the British towards the end of the war. Initially they were nothing more than a buried high-explosive shell or mortar bomb with its fuze upright. Later, purpose-built mines were developed, including the Flachmine 17, which was simply a wooden box packed with explosives and triggered either remotely or by a pressure fuze. By the end of the war, the Germans had developed row mining techniques, and mines accounted for 15% of U.S. tank casualties during the Battle of Saint-Mihiel, Third Battle of t ...

Tellermine 29
The Tellermine 29 is a round, metal-cased German anti-tank blast landmine. It first entered service in 1929, and the initial German defence plan was to purchase 6,000 a year, but in January 1931 it was decided to speed up the purchase process, and 61,418 were ordered. By 1937, with the introduction of the Tellermine 35, it was being used for training, and the majority were sent to warehouses.Инженерные боеприпасы (T-Mi-42) - tmi-42.html The mine did see limited service during the , notably after |
Tellermine 35
The Tellermine 35 (T.Mi.35) was a German metal-cased anti-tank mine used extensively during the Second World War. The mine's case is made of sheet steel, and has a slightly convex pressure plate on the top surface with a central fuze well. Two secondary fuze wells are located on the side and bottom of the mine for anti-handling devices. For use on beaches and underwater the mine could be deployed inside a specially designed earthenware or concrete pot, which acted as a waterproof jacket for the mine. A later variant of the mine, the T.Mi.35 (S) was produced with a ribbed case and a fuze cover. The ribbed case stopped sand from blowing off the top of the mine when it was used in a desert or sandy environment. Pressure of on the center of the mine or on its edge deforms the pressure plate compressing a spring, and breaking a shear pin which holds back the spring-loaded striker. Once the striker is released it flips downwards into a percussion cap which fires the adjacent deton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesarchiv Bild 101I-315-1143-29, Italien, Minen Z42 An Baumstamm
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media ( Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the ...

Wehrmacht
The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the German Army (1935–1945), ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force). The designation "''Wehrmacht''" replaced the previously used term (''Reich Defence'') and was the manifestation of the Nazi regime's efforts to German rearmament, rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Adolf Hitler's rise to power, Nazi rise to power in 1933, one of Adolf Hitler's most overt and bellicose moves was to establish the ''Wehrmacht'', a modern offensively-capable armed force, fulfilling the Nazi regime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbours. This required the reinstatement of conscription and massive investment and Military budget, defence spending on the arms industry. The ''Wehrmacht'' formed the heart of Germany's politico-military po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detonation
Detonation () is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with speeds about 1 km/sec and differ from deflagrations which have subsonic flame speeds about 1 m/sec. Detonation may form from an explosion of fuel-oxidizer mixture. Compared with deflagration, detonation doesn't need to have an external oxidizer. Oxidizers and fuel mix when deflagration occurs. Detonation is more destructive than deflagrations. In detonation, the flame front travels through the air-fuel faster than sound; while in deflagration, the flame front travels through the air-fuel slower than sound. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases. TNT, dynamite, and C4 are examples of high power explosives that detonate. The detonation velocity, velocity of detonation in solid an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demining
Demining or mine clearance is the process of removing land mines from an area. In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves. By contrast, the goal of ''humanitarian demining'' is to remove all of the landmines to a given depth and make the land safe for human use. Specially trained dogs are also used to narrow down the search and verify that an area is cleared. Mechanical devices such as flails and excavators are sometimes used to clear mines. A great variety of methods for detecting landmines have been studied. These include electromagnetic methods, one of which (ground penetrating radar) has been employed in tandem with metal detectors. Acoustic methods can sense the cavity created by mine casings. Sensors have been developed to detect vapor leaking from landmines. Animals such as rats and mongooses can safely move over a minefield and detect mines, and animals can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
