Self-propelled Howitzer
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and self-propelled rocket artillery. They are high-mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and tank destroyers, which were typically well-armoured vehicles often based upon the chassis of a tank. In lieu of the standard tank's general-purpose main gun that fired both high-explosive and anti-tank ammunition, direct-fire vehicles had specialized roles, with assault guns providing close fire-support for infantry and tank destroyers mounting an anti-t ...

Water-cooled
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs and other components. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmosph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

KH178 105 Mm Towed Howitzer
The KH178 ("Korean Howitzer 1 (First) 78") is a South Korean 105 mm 38 caliber towed howitzer. It was designed and developed by the Agency for Defense Development (ADD) for the Republic of Korea Armed Forces and manufactured by Hyundai WIA. History In 1976, the plan for a domestic 105 mm howitzer design was scrapped, and the factories began preparing for mass production of KM101A1 with assistance from the United States. In June, South Korea continued its development work by importing two newly introduced British 105mm L118 light guns (an air-portable towed howitzer) for evaluation. In 1977, the mass production of KM101 began and South Korea quickly boosted manufacturing capacity. In March 1978, South Korea obtained partial blueprints of the West German 105 mm lightweight howitzer and produced an operational sample, which contributed to the further development of the new howitzer. After a series of technical breakthroughs South Korea launched the developed KH178 105 mm howitzer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koksan (artillery)
M-1978 Koksan (), a name used by US military analysts, known by its makers as the Chuch'ep'o (Juche Cannon; ), is a North Korean self-propelled gun based on the Type 59 tank chassis. Some guns were exported to Middle Eastern countries in the late 1980s and used during the Iran-Iraq War. The M-1989 Koksan variant has seen use in the Kursk offensive (2024–present). Development According to former ''Janes'' editor, Christopher F Foss, the Koksan is based on a Chinese Type 59 tank chassis, while Mitzer and Oliemans note the possibility of being a Soviet T-54/T-55 tank chassis instead. The 170 mm gun is in an open mount with no superstructure and is stabilized when firing by two large folding spades at the rear. It also has a multislotted muzzle brake (but no fume extractor) and probably a power rammer. Elevation and traverse appear to be powered, although gun traverse is very limited to avoid overstressing the chassis. The gun has a range that would allow it to strike Seo ...

M109 Howitzer
The M109 is an American 155 mm turreted self-propelled howitzer, first introduced in the early 1960s to replace the M44 and M52. It has been upgraded a number of times, most recently to the M109A7. The M109 family is the most common Western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions. It has a crew of four: the section chief/commander, the driver, the gunner, and the ammunition handler/loader. The British Army replaced its M109s with the AS-90. Several European armed forces have or are currently replacing older M109s with the German PzH 2000. Upgrades to the M109 were introduced by the U.S. (see variants) and by Switzerland (KAWEST). With the cancellation of the U.S. Crusader, non-line-of-sight cannon and M1299 the M109A6 ("Paladin") will likely remain the principal self-propelled howitzer for the U.S. until a replacement enters service. Operational history The M109 was the medium variant of a U.S. program to adopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
