Altay (tank)
Altay ''(English: Red foal/colt or Altai)'' is a Turkish fourth generation main battle tank designed by Otokar based on South Korean K2 Black Panther to be produced by BMC under design assistance and technology transfer by Hyundai Rotem. It is named in honor of Army General Fahrettin Altay who commanded the 5th Cavalry Corps in the final stage of the Turkish War of Independence. With a unit cost of 13.75 million dollars, the tank design cost is on par with and competitive when compared with relative projects. The first mass production of Altay will be combined with MKE made 55 calibre 120 mm main gun, Roketsan made both advanced composite and reactive armor package along with Aselsan made electronics such as active protection, remote controlled weapon and fire control systems while using HD Hyundai Infracore engine and SNT Dynamics transmission. The tank is in production according to the Turkish media. According to the latest information published on Januar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Composite Armor
Composite armour is a type of vehicle armour consisting of layers of different materials such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles. HEAT had posed a serious threat to armoured vehicles since its introduction in World War II World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers.

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 ...

Hydropneumatic Suspension
Hydropneumatic suspension is a type of motor vehicle suspension system, invented by Paul Magès, produced by Citroën, and fitted to Citroën cars, as well as being used under licence by other car manufacturers. Similar systems are also widely used on modern tanks and other large military vehicles. The suspension was referred to as ' in early literature, pointing to oil and air as its main components. The purpose of this system is to provide a sensitive, dynamic and high-capacity suspension that offers superior ride quality on a variety of surfaces. A hydropneumatic system combines the advantages of hydraulic systems and pneumatic systems so that gas absorbs excessive force and liquid in hydraulics directly transfers force. The suspension system usually features both self-leveling and driver-variable ride height, to provide extra clearance in rough terrain. This type of suspension for automobiles was inspired by the pneumatic suspension used for aircraft landing gear, which wa ...

Stroke Ratio
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place ''outside'' the working cylinders of the engine. Conventions The contemporary convention for describing the ''stroke ratio'' of a piston engine‘s cylinders is its ''bore/stroke'' ratio. ''Stroke/bore'' ratio is an obsolete expression dating to the early era of reciprocating engine development. Bore/stroke ratio The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio. Square, oversquare and undersquare engines The following terms describe the naming conventions for the configurations of the various bore/stroke ratio: Square A square ...

Coaxial
In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is ''concentric''. Common examples: A coaxial cable has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. Coaxial rotors are a three-dimensional planar structure: a pair of helicopter rotors (wings) mounted one above the other on concentric shafts, with the same axis of rotation (but turning in opposite directions). In loudspeaker design, coaxial speakers are a loudspeaker system in which the individual drivers are mounted close to one another on the same axis, and thus radiate sound along t ...

Remote Controlled Weapon Station
A remote controlled weapon station (RCWS), remotely operated weapon system (ROWS), or remote weapon system (RWS), is a remotely operated light or medium-caliber weapon system, often equipped with a fire-control system, that can be installed on a ground combat vehicle or sea- and air-based combat platform. Such equipment is used on modern military vehicles, as it allows a gunner to remain in the relative protection of the vehicle. It may be retrofitted onto existing vehicles, for example, the CROWS system is being fitted to American Humvees.

MKE 120 Mm Tank Gun
The MKE 120 mm gun is a Turkish 120 mm 55 caliber smoothbore gun based on the CN08 120 mm gun produced by the Turkish company Mechanical and Chemical Industry Corporation, used on the Turkish Altay tank. The gun has a length of . The gun can fire ammunition with high muzzle velocity, and is made of chrome-plated "special steel". Background The MKE 120 mm gun was produced by transferring CN08 120 mm gun production technology from Hyundai WIA in South Korea through the Altay tank development project from 2008 to 2015. MKE modified the design per Altay requirements and produce the gun under license. The design of the tank gun is the same as CN08, but there are two differences: unlike CN08, thermal sleeve is equipped with static muzzle reference system (SMRS), and Altay's turret does not have breech opening motor and automatic feeding magazine system for autoloader mechanism, so ammunition can only be loaded manually by tank crew and can fire up to 6 rounds a minute.
