Panhard EBR
The Panhard EBR (Panhard ''Engin Blindé de Reconnaissance'', French: Armored Reconnaissance Vehicle) is an armoured car designed by Panhard for the French Army and later used across the globe, notably by the French Army during the Algerian War and by the Portuguese Army during the Overseas War. Development history The EBR is an 8x8 wheeled reconnaissance vehicle based on the previous Panhard AM 40 P/Model 201, a light armored car born before the Second World War, but remained only at prototype level. After the war the new contest for a postwar armored car saw the Panhard proposal as winner against two other French firms. While the two basic concepts developed with the M.201 were retained (8 wheels and oscillating turret), the new armoured car was a new project, much heavier (13 t vs 8), with a larger crew (4 vs 2) and a 75 mm gun (vs 25 mm). Other innovations included new anti-bullet Michelin tyres and Veil-Picard tubes, which feature a series of nitrogen-filled ce ...

Panhard AM 40 P
The Panhard AM 40 P, also known as Model 201, was a prototype French armoured car. History In 1938, the French Army was concerned by the lack of heavily armoured vehicles in their arsenal. In the same year, the French High Command initiated a competition for a "powerful armored car" (''Automitrailleuse Puissante''). Panhard took part in this competition and designed the Panhard AM 40 P under the leadership of Louis Delagarde. Description The Panhard AM 40 P was a groundbreaking armoured car for its time. The prototype had a low profile which made it harder to detect and was perfect for reconnaissance missions. It was manned by a crew of two. It has an uncommon 8x8 wheel configuration. A pair of bulletproof pneumatic steering wheels was located in the front while another pair of bulletproof pneumatic wheels was placed at the rear axle. Two pairs of metal wheels with grousers were attached in the center of the hull to improve cross country performance. They could be raised when ...

France borders Belgium, Luxembourg, Germany, Switzerland, Monaco, Italy, Andorra, and Spain in continental Europe, as well as the Netherlands, Suriname, and Brazil in the Americas via its overseas territories in French Guiana and Saint Martin. Its eighteen integral regions (five of which are overseas) span a combined area of and contain clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grouser
Grousers are devices intended to increase the traction of continuous tracks, especially in loose material such as soil or snow. This is done by increasing contact with the ground with protrusions, similar to conventional tire treads, and analogous to athletes' cleated shoes. On tanks and armoured vehicles, grousers are usually pads attached to the tracks; but on construction vehicles they may take the form of flat plates or bars. Similar traction-improving patterns have been implemented on the surface of the wheels on tractors. These include strakes, where material is removed from the surface of the wheel to achieve protrusion; cleats, with spikes instead of straight bars; and lugs with raised rubber on a tire tread. Variations Developed during World War I, external track extensions – often called "grousers" or "duckbills" – were added to the outside edges of the trackshoes on armored fighting vehicles such as tanks, widening the track for improved performance i ...

Haynes Manuals
The Haynes Owner's Workshop Manuals (commonly known as Haynes Manuals) are a series of practical manuals from the British publisher Haynes Publishing Group. The series primarily focuses upon the maintenance and repair of automotive vehicles, covering a wide range of makes and models (300 models of car and 130 models of motorcycle); the manuals are aimed mainly at DIY enthusiasts rather than professional garage mechanics, as they lack the depth of coverage on particular vehicles or problems. The series includes a range of 'practical lifestyle' manuals in the same style for a range of topics, including domestic appliances and personal computers, digital photography, model railways, sport, animal care, men, babies, sex, and women. They also now publish the Bluffer's Guides collection. Additionally, Haynes have released manuals based on popular fictional series including '' Star Trek'' and ''Thomas and Friends''. History The Haynes manuals are named after John Harold Haynes (1938 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armoured Personnel Carrier
An armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre." Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less armament and are not designed to provide direct fire support in battle. Infantry units which travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units which use APCs and infantry units which use IFVs, with the latter being known as armoured infantry in such militaries.

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Unde ...

AMX-13
The AMX-13 is a French light tank produced from 1952 to 1987. It served with the French Army, as the Char 13t-75 Modèle 51, and was exported to more than 26 other nations. Named after its initial weight of 13 tonnes, and featuring a tough and reliable chassis,''The Complete Guide to Tanks and Armoured Fighting Vehicles'', it was fitted with an oscillating turret built by GIAT Industries (now Nexter) with revolver type magazines, which were also used on the Austrian SK-105 Kürassier. Including prototypes and export versions, over a hundred variants exist, including self-propelled guns, anti-aircraft systems, APCs, and ATGM versions. Development The tank was designed at the Atelier de Construction d'Issy-les-Moulineaux (AMX) in 1946 to meet a requirement for an air-portable vehicle to support paratroopers. The first prototype ran from 1948. The compact chassis had torsion bar suspension with five road-wheels and two return rollers; the engine runs the length of the tank on ...

M24 Chaffee
The M24 Chaffee (officially Light Tank, M24) was an American light tank used during the later part of World War II; it was also used in post–World War II conflicts including the Korean War, and by the French in the War in Algeria and the First Indochina War. In British service it was given the service name Chaffee after the United States Army General Adna R. Chaffee Jr., who helped develop the use of tanks in the United States armed forces. Although the M41 Walker Bulldog was developed as a replacement, M24s were not mostly removed from U.S. and NATO armies until the 1960s and remained in service with some Third World countries. Development and production history British combat experience in the North African campaign identified several shortcomings of the M3 Stuart light tank, especially the performance of its 37 mm cannon. A 75 mm gun was experimentally fitted to a Howitzer Motor Carriage M8 – an M3 tank with a larger turret – and trials indicated that a ...

M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the main 75 mm gun into a fully traversing central turret. One feature, a one-axis gyrostabilizer, was not precise enough to allow firing when moving but did help keep the gun aimed in rou ...

Petrol
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

Octane
Octane is a hydrocarbon and an alkane with the chemical formula , and the condensed structural formula . Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol). As with all low-molecular-weight hydrocarbons, octane is volatile and very flammable. Use of the term in gasoline "Octane" is colloquially used as a short form of " octane rating," particularly in the expression "high octane". "Octane rating" is an index of a fuel's ability to resist engine knock in engines having different compression ratios, which is a characteristic of octane's branched-chain isomers, especially iso-octane. The octane rating of gasoline is not directly related to the power output of an engine. Using gasoline of a higher octane than an engine is designed for canno ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...
