K2 Black Panther
The K2 Black Panther (Hangul: K2 '흑표'; Hanja: K2 '黑豹') is a South Korean main battle tank designed by the Agency for Defense Development and manufactured by Hyundai Rotem. The tank was designed to meet the strategic requirements of the Republic of Korea Army's reform for three-dimensional high-speed maneuver warfare based on use of network-centric warfare began in the 1990s. Mass production commenced in 2013 and the first K2s were deployed with the armed forces in July 2014. Development South Korea has been accumulating tank development and production technology to increase self-reliance in producing arms. In 1976, South Korea managed to increase tank production during the M48 Patton upgrade. In 1987, the K1 88-Tank, designed by General Dynamics Land Systems, was commissioned for service, which South Korea participated in the development and gained tank development capability. However, K1 was basically an American designed M1 Abrams derivative produced in South Korea, ... [...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, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter-weight composite armor allowed the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. Through 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 armored fighting vehicles. Main battle tanks are a key component of modern armies.#House1984, House (1984), ''Toward Combined Arms Warfare: A Survey of 20th-Century Tactics, Doctrine, and Organization'' Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in inf ...

CN08 120 Mm Gun
The CN08 is a 120 mm 55-caliber smoothbore gun produced by Hyundai WIA. It is incorrectly known as the licensed production of the Rheinmetall Rh-120 L/55, but it was indigenously developed by the Agency for Defense Development and WIA (now Hyundai WIA) from 2003 to 2008 for the XK2 development project started in 1995. The development was completed after the operational test ended in September 2008. Description The CN08 is the main armament of the K2 Black Panther, and the gun barrel is applied with internal chrome plating technology for the large-caliber gun. The gun barrel can endure a high explosive force as a result of the increased stiffness and wear resistance provided by this internal chromium surface. The main components, including the breech ring, breech block and thermal sleeve, are simplified and designed lightly, the gun barrel weighs 1324 kg and the gun mount weighs 3103 kg. The gun mount consists of a hydro-pneumatic recoil system and is complemented by a bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hanja
Hanja (Hangul: ; Hanja: , ), alternatively known as Hancha, are Chinese characters () used in the writing of Korean. Hanja was used as early as the Gojoseon period, the first ever Korean kingdom. (, ) refers to Sino-Korean vocabulary, which can be written with Hanja, and (, ) refers to Classical Chinese writing, although "Hanja" is also sometimes used to encompass both concepts. Because Hanja never underwent any major reforms, they are mostly resemble to ''kyūjitai'' and traditional Chinese characters, although the stroke orders for some characters are slightly different. For example, the characters and as well as and . Only a small number of Hanja characters were modified or are unique to Korean, with the rest being identical to the traditional Chinese characters. By contrast, many of the Chinese characters currently in use in mainland China, Malaysia and Singapore have been simplified, and contain fewer strokes than the corresponding Hanja characters. In Japan, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hangul
The Korean alphabet, known as Hangul, . Hangul may also be written as following South Korea's standard Romanization. ( ) in South Korea and Chosŏn'gŭl in North Korea, is the modern official writing system for the Korean language. The letters for the five basic consonants reflect the shape of the speech organs used to pronounce them, and they are systematically modified to indicate phonetic features; similarly, the vowel letters are systematically modified for related sounds, making Hangul a featural writing system. It has been described as a syllabic alphabet as it combines the features of alphabetic and syllabic writing systems, although it is not necessarily an abugida. Hangul was created in 1443 CE by King Sejong the Great in an attempt to increase literacy by serving as a complement (or alternative) to the logographic Sino-Korean ''Hanja'', which had been used by Koreans as its primary script to write the Korean language since as early as the Gojoseon period (spanni ...

Hydropneumatic Suspension
Hydropneumatic suspension is a type of motor vehicle suspension system, designed by Paul Magès, invented by Citroën, and fitted to Citroën cars, as well as being used under licence by other car manufacturers, notably Rolls-Royce ( Silver Shadow), Bmw 5-Series e34 Touring, Maserati (Quattroporte II) and Peugeot. It was also used on Berliet trucks and has more recently been used on Mercedes-Benz cars, where it is known as ''Active Body Control.'' The Toyota Soarer UZZ32 "Limited" was fitted with a fully integrated four-wheel steering and a complex, computer-controlled hydraulic ''Toyota Active Control Suspension'' in 1991. Similar systems are also widely used on modern tanks and other large military vehicles. The suspension was referred to as ''oléopneumatique'' 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 surface ...

Stroke Ratio
In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length. 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. A fairly comprehensive yet understandable study of stroke/bore effects was published in ''Horseless Age'', 1916. Conventions In a piston engine, there are two different ways of describing the ''stroke ratio'' of its cylinders, namely: ''bore/stroke'' ratio, and ''stroke/bore'' ratio. Bore/stroke ratio Bore/stroke is the more commonly used term, with usage in North America, Europe, United Kingdom, Asia, and Australia. The diameter of the cylinder bore is divided by the length of the piston stroke to give the rati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
