Mendeleev Tank
The Mendeleev Tank was a proposed early tank design by Russian naval engineer Vasiliy Mendeleev, son of Russian scientist Dimitri Mendeleev, who created the modern periodic table. The vehicle was envisioned by Mendeleev during his time working at the Kronshtadt Marine Engineering School in Saint Petersburg, Russia, from 1911 to 1915. Its purported purpose was to be a "landship" immune to all enemy fire and able to cross large battlefields while providing heavy artillery support to troops using a 120 mm gun. The proposed tank was one of the heaviest tank designs of all time; at 173.2 tons it would have been nearly the same weight as the World War II German Panzer VIII Maus superheavy tank. Design The Mendeleev Tank was of a complete rectangular construction, with its main gun at the front, a machine gun turret mounted to the roof just aft of the middle and tracks protruding directly from the bottom of the hull. The tank was supposed to have a crew of eight operating it. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, ...

Panzer VIII Maus
''Panzerkampfwagen'' VIII ''Maus'' (English: 'mouse') was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armored fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed, the turret being attached before the testing grounds were captured by advancing Soviet military forces. These two prototypes underwent trials in late 1944. The complete vehicle was long, wide and high. Weighing 188 metric tons, the Maus's main armament was the Krupp-designed 128 mm KwK 44 L/55 gun, based on the 12.8 cm Pak 44 towed anti-tank gun also used in the casemate-type ''Jagdtiger'' tank destroyer, with a coaxial 75 mm KwK 44 L/36.5 gun. The 128 mm gun was powerful enough to destroy all Allied armored fighting vehicles in service at the time, with some at ranges exceeding . The principal problem in the design of the ''Maus'' was developing an engine and drivetrain which was powerful enough to a ...

Tiger II
The Tiger II is a German heavy tank of the Second World War. The final official German designation was ''Panzerkampfwagen'' Tiger ''Ausf''. B,'' Panzerkampfwagen'' – abbr: ''Pz.'' or ''Pz.Kfw.'' (English: "armoured fighting vehicle"), ''Ausf.'' is abbreviation of ''Ausführung'' (English: variant). The full titles ''Panzerkampfwagen'' Tiger ''Ausf''. B and ''Panzerbefehlswagen'' Tiger ''Ausf''. B (for the command version) were used in training and maintenance manuals and in organisation and equipment tables. (Jentz and Doyle 1997). Also sometimes referred to as "Pz. VI ''Ausf'' B", not to be confused with "Pz. VI ''Ausf'' E”, which was the Tiger I. often shortened to Tiger B.Jentz and Doyle 1993, p. 16. The ordnance inventory designation was ''Sd.Kfz.'' 182. ( ''Sd.Kfz.'' 267 and 268 for command vehicles). It was known as King Tiger by Allied soldiers, and is also known under the informal name ''Königstiger'' (the German name for the Bengal tiger which translates literally a ...

Pneumatic Suspension
Air suspension is a type of vehicle suspension powered by an electric or engine-driven air pump or compressor. This compressor pumps the air into a flexible bellows, usually made from textile-reinforced rubber. Unlike hydropneumatic suspension, which offers many similar features, air suspension does not use pressurized liquid, but pressurized air. The air pressure inflates the bellows, and raises the chassis from the axle. Overview Air suspension is used in place of conventional steel springs in heavy vehicle applications such as buses and trucks, and in some passenger cars. It is widely used on semi trailers and trains (primarily passenger trains). The purpose of air suspension is to provide a smooth, constant ride quality, but in some cases is used for sports suspension. Modern electronically controlled systems in automobiles and light trucks almost always feature self-leveling along with raising and lowering functions. Although traditionally called air bags or air bellows, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuous Track
Continuous track is a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tires on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tracks provide good trac ...

QF 6-pounder 6 Cwt Hotchkiss
The Ordnance QF 6-pounder 6 cwt Hotchkiss Mk I and Mk II was a shortened version of the original QF 6 pounder Hotchkiss, QF 6 pounder Hotchkiss naval gun, and was developed specifically for use in the sponsons of the later Marks of British tanks in World War I, from Mark IV tank, Mark IV onwards. History World War I The original QF 6 pounder Hotchkiss, QF 6 pounder naval gun had turned out to be too long for practical use with the current British heavy tank designs, which mounted guns in sponsons on the side rather than turrets on top as modern tanks do. The Muzzle (firearm), muzzles of the long barrels sometimes dug into the mud or struck obstacles when the vehicle crossed Trench warfare, trenches or shell craters. The shortened QF 6 pounder 6 cwt Mk I of single tube construction was introduced in January 1917 in the Mark IV tank, and may be considered the world's first specialised tank gun. The shortened barrel incurred a reduction in muzzle velocity, but as tank guns in World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark IV Tank
The Mark IV (pronounced ''Mark four'') was a British tank of the First World War. Introduced in 1917, it benefited from significant developments of the Mark I tank (the intervening designs being small batches used for training). The main improvements were in armour, the re-siting of the fuel tank and ease of transport. A total of 1,220 Mk IV were built: 420 "Males", 595 "Females" and 205 Tank Tenders (unarmed vehicles used to carry supplies), which made it the most numerous British tank of the war. The Mark IV was first used in mid 1917 at the Battle of Messines Ridge. It remained in British service until the end of the war, and a small number served briefly with other combatants afterwards. Development The director of the Tank Supply Department, Albert Gerald Stern, first intended to fit the Mark IV with a new engine and transmission. Production of battle tanks was halted until the new design was ready, necessitating the use of the Mark II and III as interim training tanks. ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
120mm 45 Caliber Pattern 1892
The 120mm 45 caliber Pattern 1892 was a Russian naval gun developed in the years before the Russo-Japanese War that armed a variety of warships of the Imperial Russian Navy during the Russo-Japanese War and World War I. Guns salvaged from scrapped ships found a second life on river gunboats of the Soviet Navy during the Russian Civil War and as coastal artillery and railway artillery during World War II. It was estimated that in 1941 there were 35 still in service. History In 1891 a Russian naval delegation was shown three guns designed by the French designer Canet. One was a 75/50 gun, one was a 120/45 gun, and the last was a 152/45 gun. All three guns used fixed QF ammunition which produced a rate of fire of 15 rpm for the 75/50 gun, 12 rpm for the 120/45 gun and 10 rpm for the 152/45 gun. The Russians were impressed and in 1892 they negotiated a production license for all three guns. Construction There were two main series of the 120/45 guns produced. The first serie ...
