Leopard 2
The Leopard 2 is a third generation German main battle tank (MBT). Developed by Krauss-Maffei in the 1970s, the tank entered service in 1979 and replaced the earlier Leopard 1 as the main battle tank of the West German army. Various iterations of the Leopard 2 continue to be operated by the armed forces of Germany, as well as 13 other European countries, and several non-European countries, including Canada, Chile, Indonesia, and Singapore. Some operating countries have licensed the Leopard 2 design for local production and domestic development. There are two main development tranches of the Leopard 2. The first encompasses tanks produced up to the Leopard 2A4 standard and are characterised by their vertically faced turret armour. The second tranche, from Leopard 2A5 onwards, has an angled, arrow-shaped, turret appliqué armour, together with other improvements. The main armament of all Leopard 2 tanks is a smoothbore 120 mm cannon made by Rheinmetall. This is oper ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank or simply tank,Ogorkiewicz 2018 p222 is a tank that fills the role of armour-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter composite armour allowed for the design of a tank that had the firepower of a super-heavy tank, the armour protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. The first ''designated'' MBT was the British Chieftain (tank), Chieftain tank, which during its development in the 1950s was re-designed as an MBT. Throughout the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles. Main battle tanks are a key component of modern armies.Main battle tank#House1984, House (1984), ''Toward Combined Arms Warfare: A Surve ...

Rheinmetall Rh-120
The Rheinmetall Rh-120 is a 120 mm smoothbore tank gun designed and produced in former West Germany by the Rheinmetall Waffe Munition GmbH company. It was developed in response to Soviet advances in armour technology and development of new armoured threats. Production began in 1974, with the first version of the gun, known as the ''L/44'' as it was 44 calibres long, used on the German Leopard 2 tank and soon produced under license for the American M1A1 Abrams and other tanks. The L/44 gun has a length of , and the gun system weighs approximately . By 1990, the L/44 was not considered powerful enough to defeat future Soviet armour, which stimulated an effort by Rheinmetall to develop a better main armament. This first involved a tank gun named ''Neue Panzerkanone 140'' ('new tank gun 140'), but later turned into a compromise which led to the development of an advanced 120 mm gun, the L/55, based on the same internal geometry as the L/44 and installed in the same breech ...

German Army
The German Army (, 'army') is the land component of the armed forces of Federal Republic of Germany, Germany. The present-day German Army was founded in 1955 as part of the newly formed West German together with the German Navy, ''Marine'' (German Navy) and the German Air Force, ''Luftwaffe'' (German Air Force). , the German Army had a strength of 63,047 soldiers. History Overview A German army equipped, organized, and trained following a single doctrine and permanently unified under one command was created in 1871 during the unification of Germany under the leadership of Prussia. From 1871 to 1919, the title ''German Army (German Empire), Deutsches Heer'' (German Army) was the official name of the German land forces. Following the German defeat in World War I and the end of the German Empire, the main army was dissolved. From 1921 to 1935 the name of the German land forces was the ''Reichswehr, Reichsheer'' (Army of the Realm) and from 1935 to 1945 the name ''German Army (We ...

Leopard 1
The Kampfpanzer Leopard, subsequently Leopard 1 following the introduction of the successive Leopard 2, is a main battle tank designed by Porsche and manufactured by Krauss-Maffei Wegmann, Krauss-Maffei in West Germany, first entering service in 1965. Developed in an era when HEAT warheads were thought to make conventional heavy armour of limited value, the Leopard design focused on effective firepower and mobility instead of heavy protection. It featured moderate armour, only effective against low caliber autocannons and heavy machine guns, giving it a high power-to-weight ratio. This, coupled with a modern suspension and drivetrain, gave the Leopard superior mobility and cross-country performance compared to most other main battle tanks of the era, only being rivaled by the French AMX-30 and Swedish Strv 103. The main armament of the Leopard consisted of a German license-built version of the United Kingdom, British Royal Ordnance L7 105 mm rifled gun, one of the most eff ...

List Of Main Battle Tanks By Generation
Main battle tanks are often classified as belonging to a particular generation, although the actual definition and membership in these generations are not defined. Soviet military planners organize tanks with the first generation of tanks up to 1950, and four generations of tanks (with the first main battle tank being the third-generation T-64), while American strategists organize main battle tanks into three generations."The Canadian Directorate of Land Strategic Concept defines three generations of Main Battle Tanks. The first generation of post World War II Main Battle Tanks includes the U.S. M48/M60, the German Leopard 1 and the British Centurion and Chieftain. The second generation includes most of the 120 mm Main Battle Tanks such as the American M1A1, the German Leopard 2 and the British Challenger. As for the third generation Main Battle Tank, they include the latest 'digital' tank such as the French Leclerc and perhaps the American M1A2 and the German Leopard 2A5." T ...

Torsion Bar Suspension
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M46/M47/M48 Patton, M60 and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Twin-turbo
Twin-turbo is a type of turbo layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. The ga70 1ggte was the first inline 6 twin turbo in the world. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel In a parallel configuration, two equally-sized turbochargers each receive half of the exhaust gases. Some designs combin ...

V12 Engine
A V12 engine is a twelve-Cylinder (engine), cylinder Internal combustion engine#Reciprocating engines, piston engine where two banks of six cylinders are arranged in a V engine, V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in Boat racing, racing boats. Due to the balanced nature of the engine and the smooth delivery of Engine power, power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, after which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars.

Radiator (engine Cooling)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plants or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called '' engine coolant'' through the engine block and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid ( coolant) is pumped by a coolant pump. This liquid may be water (in climates ...
