TOG1
The Tank, Heavy, TOG 1 was a prototype British heavy tank produced in the early part of the Second World War in the expectation that battlefields might end up like those of the First World War. It was designed so it could cross churned-up countryside and trenches. A single prototype was built, and followed by an improved model (the TOG 2), but interest faded with the successful performance of another cross-country design, the Churchill tank, and the mobile war that was being fought. History In July 1939, the Special Vehicle Development Committee was drawn up for future tank designs suitable for Great War conditions under Sir Albert Gerald Stern; who had been on the original Landship Committee and head of the Tank Supply Depot during World War I. The committee included others who had been instrumental in the development of the tank during the Great War: former Director of Naval Construction, Sir Eustace Tennyson d'Eyncourt, Major-general (retired) Sir Ernest Swinton, engine des ...

Super-heavy Tank
A super-heavy tank or super heavy tank is any tank that is notably beyond the standard of the class heavy tank in either size or weight relative to contemporary vehicles. Programs have been initiated on several occasions with the aim of creating an extremely resilient vehicle for penetrating enemy formations without fear of being destroyed in combat; however, only a few examples were built, and there is little evidence of any super heavy tank having seen combat. Examples were designed in the First and Second World Wars, along with a few during the Cold War. History First World War left, Model of the Flying Elephant design The first super-heavy tank was designed by the Russian naval engineer Vasily Mendeleyev who worked on the project from 1911 to 1915. The tank was envisioned to be invulnerable to almost all contemporary threats but remained on paper due to its high construction cost. Following the production of their first tanks, the British "Flying Elephant" was desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TOG 2
The Tank, Heavy, TOG II was a British super-heavy tank design produced in the early part of World War II in case the battlefields of northern France devolved into a morass of mud, trenches and craters as had happened during World War I. When this did not happen the tank was deemed unnecessary and the project terminated. A development of the TOG I design, only a single prototype was built before the project was dropped. History The second design to come out of the Special Vehicle Development Committee (nicknamed "The Old Gang" as it was made up of people who had worked on the original British tanks of the First World War) the TOG 2 was similar to the TOG 1 and kept many of its features. Instead of the track path arrangement of the TOG 1 which - like that of the First World War British tanks - ran up over the top of the hull and back down, the track path was lower on the return run and the doors were above the tracks. Ordered in 1940, built by Foster's of Lincoln, the prototy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Gerald Stern
Sir Albert Gerald Stern (24 September 1878 – 2 January 1966) was a banker who became the Secretary of the Landship Committee during World War I, where his organisational ability assisted the Committee in creating the first British tank. During the war he came into conflict with the War Office but had the advantage of direct access to the Prime Minister, and no civil service career to protect. He was removed from direct involvement in the production of tanks and sidelined.Glanfield, J ''The Devil's Chariots – The birth and secret battles of the first tanks'' Sutton Publishing, Stroud 2001 Early life Born the second son of James Julius Stern, a part of the Jewish European Stern Banking dynasty, Albert Stern was educated at Eton and Christ Church, Oxford before entering the family business, becoming known in the City of London as "The Holy Terror". Although he negotiated a large loan to the sultan of Morocco, Albert Stern had no real flair as a merchant banker. At the outbre ...

Harry Ricardo
Sir Harry Ralph Ricardo (26 January 1885 – 18 May 1974) was an English engineer who was one of the foremost engine designers and researchers in the early years of the development of the internal combustion engine. Among his many other works, he improved the engines that were used in the first tanks, oversaw the research into the physics of internal combustion that led to the use of octane ratings, was instrumental in development of the sleeve valve engine design, and invented the Diesel "Comet" Swirl chamber that made high-speed diesel engines economically feasible. Early life Harry Ricardo was born at 13 Bedford Square, London, in 1885, the eldest of three children, and only son of Halsey Ricardo, the architect, and his wife Catherine Jane, daughter of Sir Alexander Meadows Rendel, a civil engineer. Ricardo was descended from a brother of the famous political economist David Ricardo, a Sephardi Jew of Portuguese origin. He was one of the first people in England to see ...

Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, ...

Potentiometer
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load. Nomenclature There are a number of terms in the electronics industry used to describe certain types of potentiometers: * slide pot or slider pot: a potentiom ...

Char B1
The Char B1 was a French heavy tank manufactured before World War II. The Char B1 was a specialised break-through vehicle, originally conceived as a self-propelled gun with a 75 mm howitzer in the hull; later a 47 mm gun in a turret was added, to allow it to function also as a , a "battle tank" fighting enemy armour, equipping the armoured divisions of the Infantry Arm. Starting in the early twenties, its development and production were repeatedly delayed, resulting in a vehicle that was both technologically complex and expensive, and already obsolescent when real mass-production of a derived version, the Char B1 "bis", started in the late 1930s. A further up-armoured version, the Char B1 "ter", was only built in two prototypes. Among the most powerfully armed and armoured tanks of its day, the type was very effective in direct confrontations with German armour in 1940 during the Battle of France, but low speed and high fuel consumption made it ill-adapted to the wa ...

Matilda II
The Infantry Tank Mark II, best known as the Matilda, was a British infantry tank of the Second World War.Jentz, p. 11. The design began as the A12 specification in 1936, as a gun-armed counterpart to the first British infantry tank, the machine gun armed, two-man A11 Infantry Tank Mark I. The Mark I was also known as Matilda, and the larger A12 was initially known as the Matilda II or Matilda senior. The Mark I was abandoned in 1940, and from then on the A12 was almost always known simply as "the Matilda". With its heavy armour, the Matilda II was an excellent infantry support tank but with somewhat limited speed and armament. It was the only British tank to serve from the start of the war to its end, although it is particularly associated with the North Africa Campaign. Only two were available for service by the outbreak of the World War II in 1939. It was replaced in front-line service by the lighter and less costly Infantry Tank Mk III Valentine beginning in late 1941. ...

Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. A sponson's terminus is close to the cr ...
