History Of The Tank
The history of the tank includes all vehicles intended to advance under enemy fire while remaining protected. Beginning The principle of armored warfare can be compared with attempts to protect soldiers from enemy projectiles that existed since ancient times. The development of the explosion engine makes it possible to transport an armored vehicle more easily than with horses. One of the first traces of the use of an armored motor vehicle occurred during the Crimean War. Development World War I generated new demands for armoured self-propelled weapons which could navigate any kind of terrain, and this led to the development of the tank. The great weakness of the tank predecessor, the Armored car (military), armoured car, was that it required smooth terrain to move upon, and new developments were needed for cross-country capability. The tank was originally designed as a special weapon to solve an unusual tactical situation: the stalemate of the trenches on the Western Front ...

Petrol
Gasoline (North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical stabilit ...

Continuous Track
Continuous track or tracked treads are 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 tyres 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 t ...

Levavasseur Project
The Levavasseur project was an early project for a tank designed in 1903 by the French Captain Léon René Levavasseur (1860-1942) of the 6th Artillery Battalion, described as a "self propelled cannon project" (French: ''Projet de canon autopropulseur''). It is considered as the first description, made by a soldier, of what would come to be known as the tank. Levavasseur was a graduate of Ecole Polytechnique, of the promotion of 1881. According to ''Armoured Fighting Vehicles of the World'': Submission The project was submitted to the French Technical Artillery Committee (''Comité Général d'Artillerie''), and after two years of study was presented to the Army Minister by the General President of the Committee. The general described the project in letter No.135, dated 1 February 1905: Design The locomotive mechanism is then described as a type of continuous track, supporting an armoured box with a weapon: Reception The Artillery Technical Committee raised three major obje ...

Gunpowder Engine
A gunpowder engine, also known as an explosion engine or Huygens' engine, is a type of internal combustion engine using gunpowder as its fuel. The concept was first explored during the 1600s, most notably by famous Dutch polymath Christiaan Huygens. George Cayley also experimented with the design in the early 1800s as an aircraft engine, and claims to have made models that worked for a short time. There is also a persistent claim that conventional carboretted gasoline engine can be run on gunpowder, but no examples of a successful conversion can be documented. Earliest mentions The gunpowder engine is based on many previous ideas and scientific discoveries, developed by multiple people independently. Early devices just aimed at lifting and/or holding weight (usually to study and demonstrate the physics), while engines aim at doing work continuously (usually with the intention of doing something useful). Vacuum devices to lift/hold weight Leonardo da Vinci described in 1508 a de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gottfried Wilhelm Leibniz
Gottfried Wilhelm Leibniz (or Leibnitz; – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is credited, alongside Sir Isaac Newton, with the creation of calculus in addition to many other branches of mathematics, such as binary arithmetic and statistics. Leibniz has been called the "last universal genius" due to his vast expertise across fields, which became a rarity after his lifetime with the coming of the Industrial Revolution and the spread of specialized labor. He is a prominent figure in both the history of philosophy and the history of mathematics. He wrote works on philosophy, theology, ethics, politics, law, history, philology, games, music, and other studies. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in probability theory, biology, medicine, geology, psychology, linguistics and computer science. Leibniz contributed to the field ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannons
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. The earliest known depiction of cannons may have appeared in Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do not appear until the 13th century. In 1288, Yuan dynasty troops are recorded to have used hand cannons in combat, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Žižka
Jan Žižka z Trocnova a Kalicha (; 1360 – 11 October 1424) was a Czechs, Czech military leader and Knight who was a contemporary and follower of Jan Hus, and a prominent Radical Hussite who led the Taborites, Taborite faction during the Hussite Wars. Renowned for his exceptional military skill, Žižka is celebrated as a Czech Folk hero, national hero. Žižka led the Hussite forces in battles against three crusades and remained undefeated throughout his military career. Žižka was born in the village of Borovany, Trocnov, located in the Kingdom of Bohemia, into a family of lower Czech nobility. According to Piccolomini's ''Historia Bohemica'', he maintained connections within the royal court during his youth and later held the office of Chamberlain (office), Chamberlain to Queen Sofia of Bavaria. He fought in the Battle of Grunwald (15 July 1410), where he defended Radzyń Chełmiński, Radzyń against the Teutonic Knights, Teutonic Order. Later, he played a prominent rol ...

The movement began during the Renaissance in Prague and quickly spread south and then through the rest of the Kingdom of Bohemia. Eventually, it expanded into the remaining domains of the Bohemian Crown as well. The Hussites (Czech language, Czech: ''Husité'' or ''Kališníci'', "Chalice People"; Latin: ''Hussitae'') were a Czech Proto-Protestantism, proto-Protestant Christian movement influenced by both the Byzantine Rite and John Wycliffe that followed the teachings of reformer Jan Hus (floruit, fl. 1401–1415), a part of the Bohemian Reformation. The Czech lands had originally been Christianized by Byzantine Empire, Byzantine Greek missionaries Saints Cyril and Methodius, who introduced the ...

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 battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within 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- calibre 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 wheele ...
