T92 Light Tank
The T92 Light Tank, or 76-mm Gun Tank, T92, was an American light tank developed in the 1950s by Aircraft Armaments. It was designed as an airborne/airdropped replacement for the heavier M41 Walker Bulldog while retaining the mobility, protection level, and firepower of the latter. The unveiling of the Soviet PT-76 amphibious light tank pointed out that the future US light tank should be able to swim as well. Making the T92 amphibious was deemed impractical and the light gun tank program was cancelled in June 1958. Design Armament The T92 had an unusual large cleft, low-profile, turret mounting a high-velocity 76 mm T185E1 rifled gun in a cradle housing between two armored cupolas. The T185E1 was ballistically identical to the 76 mm gun M32 of the M41 light tank but it had a quick change tube and was mounted upside down to accommodate the semi-automatic loader. Empty cartridges were automatically ejected outside the vehicle through a small hatch in the rear of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Tank
A light tank is a tank variant initially designed for rapid movements in and out of combat, to outmaneuver heavier tanks. It is smaller in size with thinner armor and a less powerful main gun, tailored for better tactical mobility and ease of transport and logistics. They are primarily employed in the screening, armored reconnaissance, skirmishing, artillery observation, and supplementing landing operations in a fire support role of expeditionary forces where larger, heavier tanks are unavailable or have difficulties operating safely or efficiently. The fast light tank was a major feature of the pre-World War II army buildup, where it was expected they would be used to exploit breakthroughs in enemy lines created by slower, heavier tanks, with the goal of disrupting communications and supply lines. Numerous small tank designs and "tankettes" were developed during this period and known under a variety of names, including the " combat car". Early light tank designs were gen ...

Aluminium Alloy
An aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Arnold, 1995 Allo ...

Light Tanks Of The United States
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particles ...

Cold War Tanks Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjectivity, subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical physics, classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy ...

LVTP-5
The LVTP-5 (landing vehicle, tracked, personnel 5) is a family of amphibious armored fighting vehicles used by the Philippine Marine Corps and, formerly, the United States Marine Corps. It was designed by the BorgWarner company and built by FMC (Food Machinery Corporation) along with a few other companies. It was first accepted into service in 1956. Some 1,124 basic units were produced, plus the specialist variants, and many saw action in the Vietnam War. History The LVTP-5 was an evolution of the ''LVT-1'' to ''LVT-4'' World War II-era landing vehicle tracked The Amphibious Vehicle, Tracked (LVT) is an amphibious warfare vehicle and amphibious landing craft, introduced by the United States Navy and United States Marine Corps.

M50 Ontos
Ontos, officially the Rifle, Multiple 106 mm, Self-propelled, M50, was a U.S. light armored tracked anti-tank vehicle developed in the 1950s. It mounted six 106 mm manually loaded M40 recoilless rifles as its main armament, which could be fired in rapid succession against single targets to increase the probability of a kill. Although the actual caliber of the main guns was 105 mm, it was designated 106 mm to prevent confusion with the ammunition for the 105 mm M27 recoilless rifle, which the M40 replaced. It was produced in limited numbers for the U.S. Marines after the U.S. Army cancelled the project. The Marines consistently reported excellent results when they used the Ontos for direct fire support against infantry in numerous battles and operations during the Vietnam War. The American stock of Ontos was largely expended towards the end of the conflict and the Ontos was removed from service in 1969. Development The ''Ontos'' (Greek for "thing") proje ...

Goodrich Corporation
The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Benjamin Goodrich, the company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001. Originally a rubber manufacturing company known for automobile tires, the company diversified its manufacturing businesses throughout the twentieth century and sold off its tire business in 1986 to focus on its other businesses, such as aerospace and chemical manufacturing. The BFGoodrich brand name continues to be used by Michelin, who acquired the tire manufacturing business in 1988. Following the acquisition by United Technologies in 2012, Goodrich became a part of UTC Aerospace Systems. In 1869, Benjamin Goodrich purchased the Hudson River Rubber Company, a small business in Hastings-on-Hudson, New York. The ...

Firewall (construction)
A firewall is a fire-resistant barrier used to prevent the spread of fire. Firewalls are built between or through buildings, structures, or electrical substation transformers, or within an aircraft or vehicle. Applications Firewalls can be used to subdivide a building into separate fire areas and are constructed in accordance with the locally applicable building codes. Firewalls are a portion of a building's passive fire protection systems. Firewalls can be used to separate-high value transformers at an electrical substation in the event of a mineral oil tank rupture and ignition. The firewall serves as a fire containment wall between one oil-filled transformer and other neighboring transformers, building structures, and site equipment. Types There are three main classifications of ''fire rated walls'': fire walls, fire barriers, and fire partitions. *A ''firewall'' is an assembly of materials used to separate transformers, structures, or large buildings to prevent the ...

Fiberglass Reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, World War 1, Supermarine Nighthawk, an anti-Zeppelin night fighter.Andrews and Morgan 1987, p. 21.
