Type 63 (light Tank)
The Norinco Type 63 () is a Chinese amphibious light tank. First fielded in 1963, it is in many ways similar to the earlier Soviet PT-76. However, contrary to the popular belief, it does have some essential differences from the PT-76 in the vehicle's waterjet propulsion system, etc. It is also known under its industrial designation, the WZ-211. Type 63 is being replaced by Type 63A. Development history The Chinese obtained a few PT-76 amphibious light tanks from the Soviet Union in the mid-1950s. In October 1958, the PLA decided to develop an indigenous amphibious tank based on the PT-76 design. The development program was carried out by 201 Institute and the 615 Factory. A prototype known as WZ-211 (Type 60) was built and tested in 1959, but the design suffered from a number of problems including engine overheating. The PLA wasn't satisfied with the performance of the vehicle, which led to the development of an improved version. It was jointly developed by Military Engineeri ...

Coaxial
In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is ''concentric''. Common examples: A coaxial cable is a three-dimensional linear structure. It has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. Coaxial rotors are a three-dimensional planar structure: a pair of helicopter rotors (wings) mounted one above the other on concentric shafts, with the same axis of rotation (but turning in opposite directions). In loudspeaker design, coaxial speakers A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate s ...

Taiwan Strait
The Taiwan Strait is a -wide strait separating the island of Taiwan and continental Asia. The strait is part of the South China Sea and connects to the East China Sea to the north. The narrowest part is wide. The Taiwan Strait is itself a subject of international dispute over its political status. As the People's Republic of China claims to enjoy "sovereignty, sovereign rights and jurisdiction over the Taiwan Strait" and regards the waterway as " internal territorial waters" instead of being international waters, this means that the Chinese government denies any foreign vessel having the freedom of navigation in the strait. This position has drawn strong objections from the United States, Australia, France and Taiwan. Names Former names of the Taiwan Strait include the or from a dated name for Taiwan; the or Fujian, from the Chinese province forming the strait's western shore; and the , a calque of the strait's name in Hokkien and Hakka.

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named ''Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, scale an ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
