Otaman 6x6
The Otaman 6x6 is an armoured fighting vehicle produced by the Ukrainian manufacturer NGO Practika and presented for the first time at the Indian Defexpo in 2016, followed by the Otaman 8x8 in the Arms and Security Exhibition held in Kyiv in 2017. This armoured fighting vehicle (AFV) can also be used as an armoured personnel carrier (APC), an infantry fighting vehicle (IFV), and as an ambulance. Description The Otaman 6x6 is based on the BTR-60 APC. It is powered by a single 320 hp engine and has a torque of 1250 N⋅m. It has a length of and it weighs 16 tons. It can carry three members of the crew (commander, driver and gunner) and ten army personnel. The 6x6 is mainly produced for the Ukrainian army, but is also exported. It is an agile APC, like the BTR-80 but with more firepower, because of the 122 mm howitzer that it has as the primary armament. This gun has an operational range of about and can also heavily damage tanks while moving with precision, allowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otaman 6x6 1
Ataman (variants: ''otaman'', ''wataman'', ''vataman''; Russian: атаман, uk, отаман) was a title of Cossack and haidamak leaders of various kinds. In the Russian Empire, the term was the official title of the supreme military commanders of the Cossack armies. The Ukrainian version of the same word is '' hetman''. ''Otaman'' in Ukrainian Cossack forces was a position of a lower rank. Etymology The etymologies of the words ''ataman'' and '' hetman'' are disputed. There may be several independent Germanic and Turkic origins for seemingly cognate forms of the words, all referring to the same concept. The ''hetman'' form cognates with German '' Hauptmann'' ('captain', literally 'head-man') by the way of Czech or Polish, like several other titles. The Russian term ''ataman'' is probably connected to Old East Slavic ''vatamanŭ,'' and cognates with Turkic ''odoman'' (Ottoman Turks). The term ''ataman'' may had also a lingual interaction with Polish ''hetman'' and German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Wheeled Armoured Fighting Vehicles
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word ''wheel'' comes from the Old English word , from Proto-Germanic , from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armoured Personnel Carriers Of The Post–Cold War Period
Armour (British English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some mostly ground attack combat aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat". The word originates from the Old French , itself der ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

122 Mm Howitzer 2A18 (D-30)
The 122-mm howitzer D-30 ( GRAU index 2A18) is a Soviet howitzer that first entered service in 1960. It is a robust piece that focuses on the essential features of a towed field gun suitable for all conditions. The D-30 has a maximum range of 15.4 kilometers, or over 21 km using rocket-assisted projectile ammunition. With its striking three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the nations of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces. The barrel assembly of the 2A18 gun is used by the 2S1 self-propelled howitzer. There are also Egyptian, Chinese, Serbian and Syrian self-propelled variants and conversions. The Syrian conversion utilizes the hull of a T-34 tank. History The 122 mm (originally 48 lines) calibre was adopted by Russia in the early 20th century, becoming very important to Soviet artil ...

Tank Destroyer
A tank destroyer, tank hunter, tank killer, or self-propelled anti-tank gun is a type of armoured fighting vehicle, armed with a direct fire artillery gun or missile launcher, designed specifically to engage and destroy enemy tanks, often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a tracked tank chassis, while others are wheeled. Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the first two decades of the 21st century has s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BTR-80
The BTR-80 (russian: бронетранспортёр, bronyetransportyor, literally "armoured transporter") is an 8×8 wheeled amphibious armoured personnel carrier (APC) designed in the USSR. It was adopted in 1985 and replaced the previous vehicles, the BTR-60 and BTR-70, in the Soviet Army. It was first deployed during the Soviet–Afghan War. The BTR-80 was developed into the larger BTR-90. Description The Soviets based the BTR-80 on the BTR-70 APC, which itself was based on the BTR-60. It has a single 260-hp V-8 turbocharged water-cooled diesel engine, an improvement over the twin gasoline engines installed in the BTR-60 and BTR-70 vehicles. The reconfigured rear portion of the hull accommodates the new, single engine. The Soviets removed the roof chamfers of the modified BTR-70, raised the rear, and squared off the rearward-sloping engine compartment. Standard equipment includes TNPO vision blocks, TNP-B and TKN-3 optical devices for the driver and commander, an OU ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infantry Fighting Vehicle
An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit. Infantry fighting vehicles are distinct from armored personnel carriers (APCs), which are transport vehicles armed only for self-defense and not specifically engineered to fight on their own. IFVs are designed to be more mobile than tanks and are equipped with a rapid-firing autocannon or a large conventional gun; they may include side po ...
