Type 8105 Naval Trawler
Type 8105 naval trawler is a Chinese auxiliary ship of the People's Liberation Army Navy (PLAN).Type 8105 along with Type 792 and Type 8154 naval trawlers have all received NATO reporting name FT-14 AIT class,meaning Fishing Trawler - 14 Auxiliary Intelligence-gathering Trawler. After retiring from their original role of a spy ship, Type 8105 naval trawlers have been converted to auxiliary minesweepers and survey vessels, and kept in operational reserve of the Chinese navy. Type 113 naval trawler The origin of Type 8105 naval trawler is Type 113 naval trawler, which is a development of Shanghai Fishing (Hu-Yu, 沪渔) 401 series fishing trawler designed in 1954 and built in 1954, the first fishing trawler built in the People’s Republic of China (PRC). The 401 series was based on Japanese fishing trawler design, and during its service, some of the design flaws had surfaced, thus in 1956, Qingxin Shipyard (求新造船厂) completed two rounds of major redesign efforts for impro ...

Gross Ton
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces. History The International Convention on Tonnage Measurement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Replenishment Oiler
A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers. The United States Navy's hull classification symbol for this type of ship was AOR. Replenishment oilers are slower and carry fewer dry stores than the U.S. Navy's modern fast combat support ships, which carry the classification AOE. History The development of the "oiler" paralleled the change from coal- to oil-fired boilers in warships. Prior to the adoption of oil fired machinery, navies could extend the range of their ships either by maintaining coaling stations or for warships to raft together with colliers and for coal to be manhandled aboard. Though arguments related to fuel security were made against such a change, the ease with which liquid fuel could be transferred led in part to its adoption by navies worldwide. One of the first ...

South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by the shores of South China (hence the name), in the west by the Indochinese Peninsula, in the east by the islands of Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan (e.g. the Mindoro and Balabac Straits), the Strait of Malacca via the Singapore Strait, and the Java Sea via the Karimata and Bangka Straits. The Gulf of Thailand and the Gulf of Tonkin are also part of the South China Sea. The shallow waters south of the Riau Islands are also known as the Natuna Sea. The South China Sea is a region of tremendous economic and geostrategic importance. One-third of the world's maritime shipping passe ...

Soviet Aircraft Carrier Minsk
''Minsk'' is an aircraft carrier (heavy aircraft cruiser in Russian classification) that served the Soviet Navy and the Russian Navy from 1978 to 1994. She was the second vessel to be built. From 2000 to 2016 it was a theme park known as Minsk World in Shatoujiao, Yantian, Shenzhen, China. In April 2016, ''Minsk'' was towed to Jiangsu for exhibition. History Russian service Named after the capital city of Belarus, ''Minsk'' was laid down in 1972, launched on 30 September 1975, completed on 27 September 1978, and decommissioned on 30 June 1993. ''Minsk'' operated with the Pacific Fleet. Shortly after the Sino-Vietnamese War of 1979, ''Minsk'' was deployed to the South China Sea, making a port of call at Cam Ranh Bay, Vietnam, in September 1980. She visited Vietnam again in 1982 during her second deployment before sailing onto the Indian Ocean. In 1984, ''Minsk'', the landing ship ''Aleksandr Nikolayev'', and Vietnam forces conducted the Soviet Navy's first amphibious lan ...

Environmental Issues In China
Environmental issues in China had risen in tandem with the country's rapid industrialisation, as well as lax environmental oversight especially during the early 2000s. China was ranked 120th out of the 180 countries on the 2020 Environmental Performance Index. The Chinese government has acknowledged the problems and made various responses, resulting in some improvements, but western media has criticized the actions as inadequate. In recent years, there has been increased citizens' activism against government decisions that are perceived as environmentally damaging, and a retired government official claimed that the year of 2012 saw over 50,000 environmental protests in China. Since the 2010s, the government has given greater attention to environmental protection through policy actions such as the signing of the Paris climate accord, the 13th Five-Year Plan and the 2015 Environmental Protection Law reform From 2006 to 2017, sulphur dioxide levels in China were reduced by 70 p ...

Planned Economy
A planned economy is a type of economic system where investment, production and the allocation of capital goods takes place according to economy-wide economic plans and production plans. A planned economy may use centralized, decentralized, participatory or Soviet-type forms of economic planning. The level of centralization or decentralization in decision-making and participation depends on the specific type of planning mechanism employed. Socialist states based on the Soviet model have used central planning, although a minority such as the former Socialist Federal Republic of Yugoslavia have adopted some degree of market socialism. Market abolitionist socialism replaces factor markets with direct calculation as the means to coordinate the activities of the various socially-owned economic enterprises that make up the economy. More recent approaches to socialist planning and allocation have come from some economists and computer scientists proposing planning mechanisms based on ...

Chinese Economic Reform
The Chinese economic reform or reform and opening-up (), known in the West as the opening of China, is the program of economic reforms termed " Socialism with Chinese characteristics" and "socialist market economy" in the People's Republic of China (PRC). Led by Deng Xiaoping, often credited as the "General Architect", the reforms were launched by reformists within the Chinese Communist Party (CCP) on December 18, 1978, during the "Boluan Fanzheng" period. The reforms went into stagnation after the military crackdown on 1989 Tiananmen Square protests, but were revived after Deng Xiaoping's Southern Tour in 1992. In 2010, China overtook Japan as the world's second-largest economy by nominal GDP and in 2017 overtook the United States by becoming the world's largest economy by GDP (PPP). Prior to the reforms, the Chinese economy was dominated by state ownership and central planning. From 1950 to 1973, Chinese real GDP per capita grew at a rate of 2.9% per year on average, albei ...

Anchor Windlass
A windlass is a machine used on ships that is used to let-out and heave-up equipment such as a ship's anchor or a fishing trawl. On some ships, it may be located in a specific room called the windlass room. An anchor windlass is a machine that restrains and manipulates the anchor chain on a boat, allowing the anchor to be raised and lowered by means of chain cable. A notched wheel engages the links of the chain or the rope. A trawl windlass is a similar machine that restrains or manipulates the trawl on a commercial fishing vessel. The trawl is a sort of big fishing net that is wound on the windlass. The fishermen either let-out the trawl or heave-up the trawl during fishing operations. A brake is provided for additional control. The windlass is usually powered by an electric or hydraulic motor operating via a gear train. Horizontal or vertical Technically speaking, the term "windlass" refers only to horizontal winches. Vertical designs are correctly called capstans. Horizon ...

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 ...

V6 Engine
A V6 engine is a six-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and Delahaye. Engines built after World War II include the Lancia V6 engine in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special. The V6 layout has become the most common layout for six-cylinder automotive engines. Design Due to their short length, V6 engines are often used as the larger engine option for vehicles which are otherwise produced with inline-four engines, especially in transverse engine vehicles. A downside for luxury cars is that V6 engines produce more vibrations than straight-six engines. Some sports cars use flat-six engines instead of V6 engines, due to their lower centre of gravity (which improves the handling). The displacement of modern V6 engines is typically between , though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Afterdeck
In naval architecture an afterdeck or after deck, or sometimes the aftdeck, aft deck or a-deck, is the open deck area toward the stern or aft back part of a ship or boat. The afterdeck can be used for a number of different purposes. Not all ships have an afterdeck. In place of the afterdeck a ship may be built with a poop deck, that is a deck that forms the roof of a cabin built in the rear, or "aft", part of the superstructure of a ship. A poop deck usually is higher up than an afterdeck. A ship may have its superstructure or aftercastle located in the stern and thus not have an afterdeck. The stern and afterdeck of a ship are usually more smooth and stable than the bow (front) of the ship in motion. A taffrail is the handrail around the open afterdeck or poop deck. On wooden sailing ships like man-of-war or East Indiaman the taffrail is usually a hand carved wood rail and often highly decorated. Afterdeck uses * Navy war ships may use the afterdeck to mount deck guns. * M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
