TAB-71
The BTR-60 is the first vehicle in a series of Soviet eight-wheeled armoured personnel carriers (APCs). It was developed in the late 1950s as a replacement for the BTR-152 and was seen in public for the first time in 1961. BTR stands for ''Bronetransporter'' (БТР, Бронетранспортер, literally "armoured transporter"). History Origins The BTR-152 and BTR-40, the first two Soviet mass-produced APCs developed after the Second World War, gave the Soviet Army useful experience with wheeled armoured personnel carriers. However, even as they were designed, they were not suited for the needs of the Soviet Army as they lacked a roof (which was added in later versions designated BTR-152K and BTR-40B respectively). The low combat values of the BTR-152 and BTR-40 were exposed when the Egyptian Army used them during the Suez Crisis and also when the Soviet Army used them in the fighting on the streets of Budapest during the Hungarian Revolution of 1956. These were among the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BTR-70
The BTR-70 is an eight-wheeled armored personnel carrier (russian: бронетранспортер/ ''Bronetransporter'', or literally "Armoured Transporter") originally developed by the Soviet Union during the late 1960s under the manufacturing code GAZ-4905. On August 21, 1972, it was accepted into Soviet service and would later be widely exported. Large quantities were also produced under license in Romania as the ''TAB-77''. The BTR-70 was developed as a potential successor for the earlier BTR-60 series of Soviet wheeled armored personnel carriers, specifically the ''BTR-60PB'', which it most closely resembled. It evolved out of an earlier, unsuccessful project known as the ''GAZ-50'' to design a new wheeled infantry fighting vehicle on the chassis and drive train of a BTR-60PB. It initially received the NATO reporting name ''BTR M1970''. Development History In 1971, the Soviet Armed Forces began investigating the possibility of an updated BTR-60PB redesigned to make the veh ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Hungarian Revolution Of 1956
The Hungarian Revolution of 1956 (23 October – 10 November 1956; hu, 1956-os forradalom), also known as the Hungarian Uprising, was a countrywide revolution against the government of the Hungarian People's Republic (1949–1989) and the Hungarian domestic policies imposed by the Soviet Union (USSR). The Hungarian Revolution began on 23 October 1956 in Budapest when Student, university students appealed to the civil populace to join them at the Hungarian Parliament Building to protest against the USSR's geopolitical domination of Hungary with the Stalinism, Stalinist government of Mátyás Rákosi. A delegation of students entered the building of Magyar Rádió, Hungarian Radio to broadcast their Demands of Hungarian Revolutionaries of 1956, sixteen demands for political and economic reforms to the civil society of Hungary, but they were instead detained by security guards. When the student protestors outside the radio building demanded the release of their delegation of studen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...

Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Gear Box
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrapnel (fragment)
Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, or autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler. The correct term for these pieces is "fragmentation"; "shards" or "splinters" can be used for non-preformed fragments. Preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and sizes, and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated. The resulting high-velocity fragments produced by either method are the main lethal mechanisms of these weapons, rather than the heat or overpressure caused by detonation, although offensive grenades are often constructed without a frag matrix. These casing pieces are often incorrectly referred to as "shrapnel", particularly by non-military media sources. History The ...

Small Arms
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber (i.e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
