Ngô Quyền
Ngô Quyền ( vi-hantu, 吳權) (April 17, 898 – February 14, 944), often referred to as Tiền Ngô Vương (前吳王; "First King of Ngô"), was a warlord who later became the founding king of the Ngô dynasty of Vietnam. He reigned from 939 to 944. In 938, he defeated the Southern Han dynasty at the Battle of Bạch Đằng River north of modern Haiphong. The battle is usually remembered in Vietnamese national history as it ended 1,000 years of Chinese rule over Vietnam dating back to 111 BC under the Western Han dynasty. A central district in modern Haiphong is named after him. Early life and career Ngô Quyền was born in 898 AD in Đường Lâm (modern-day Sơn Tây District, Hanoi of northern Vietnam) during the Tang dynasty. He was the son of Ngô Mân, an influential official in Phong, Annan (today Phu Tho province). Ngô Mân's ancestor was Wu Ridai (Ngô Nhật Đại), a local tribal chief from Fuluzhou, Annan (Modern-day Ha Tinh Province). In 722, Wu Ri ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile ().

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] |
Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Motor Torpedo Boat Tender
Motor torpedo boat tender is a type of ship used by the U.S. Navy during World War II and Vietnam War. The motor torpedo boat tender's task was to act as a tender in remote areas for patrol boats (PT-boats) and to provide the necessary fuel and provisions for the torpedo boats she was responsible for. The type finds its root in the torpedo boat tender The torpedo boat tender was a type of warship developed at the end of the 19th century to help bring small torpedo boats to the high seas, and launch them for attack. During the Turko-Russian war in 1877, the Russians requisitioned 19 trade ve ..., developed in the 19th century. This type of ship was classified as "AGP" and is sometimes called a "patrol craft tender."

Seaplane Tender
A seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War. Terminology In maritime parlance a tender is a vessel that is used to support the operation of other vessels. In British usage, the term tender was used for small craft, with the term depot ship being used for large seagoing vessels. Flying boats and float planes even when based at home in ports and harbour had a need for small support vessels to operate.p British tenders were small craft of launch to pinnace size. These were used to ferry crews, stores and supplies between shore and the aircraft, to maintain the buoys used to mark out "taxiways" and "runways" and to keep these clear of debris to prevent foreign object damage, and in the case of ...

Barnegat Class Seaplane Tender
The ''Barnegat'' class was a large class of United States Navy small seaplane tenders (AVP) built during World War II. Thirty were completed as seaplane tenders, four as motor torpedo boat tenders, and one as a catapult training ship.''Conway's All the World's Fighting Ships 1922–1946'', p. 157 Design Before World War II, the United States Navy foresaw a need for a large force of seaplane tenders in the event of a war in the Pacific, to allow air operations from undeveloped islands and atolls. Full-size seaplane tenders (AVs) were designed to support two squadrons of flying boats each, but they were more expensive to build and had a deep draft, precluding their use in shallow harbors. The U.S. Navy therefore also planned for "small seaplane tenders" (AVPs), with a shallower draft, capable of supporting only one squadron each, but cheaper to build and able to operate in shallow waters. The AVPs were not the descendants of the "seaplane tenders (destroyer)" (AVDs); those had be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Officer
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of ''captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO rank sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregorio Del Pilar
Gregorio Hilario del Pilar y Sempio (; ; November 14, 1875 – December 2, 1899) was a Filipino general of the Philippine Revolutionary Army during the Philippine–American War. As one of the youngest generals in the Revolutionary Army, he was known for the successful assault on the Spanish barracks in the municipality of Paombong, his victory on the first phase Battle of Quingua and his last stand at the Battle of Tirad Pass during the Philippine–American War. Because of his youth, he became known as the "Boy General". He was also known as a ladies man and was described by National Artist for Literature Nick Joaquin as the "Byron of Bulacan". Early life and education Born on November 14, 1875 to Fernando H. del Pilar and Felipa Sempio of Bulacan, Bulacan, the fifth among six siblings.
