B-class Destroyer (1913)
The B class as designated in 1913 was a heterogeneous group of torpedo boat destroyers (TBDs) built for the Royal Navy in the late 1890s. They were constructed to the individual designs of their builders to meet Admiralty specifications, the uniting feature being a specified top speed of and four funnels, although the funnel spacings differed between ships. All "30 knotter" vessels with four funnels were classified by the Admiralty as the B class in 1913 to provide some system to the naming of HM destroyers. At the same time all "30 knotter" vessels with three funnels were classified by the Admiralty as the and those with two funnels became the . Fourteen vessels were built by Laird Brothers at Birkenhead (in 1903 to become part of Cammell Laird, Birkenhead), seven by Palmers Shipbuilding and Iron Company at Hebburn-on-Tyne, and one each by Armstrong Whitworth at Walker-on-Tyne, William Doxford and Sons at Sunderland, and J & G Thomson (later to become John Brown and Co ...

A-class Destroyer (1913)
The A class as designated in 1913 was a heterogeneous group of torpedo boat destroyers (TBDs) built for the Royal Navy in the mid-1890s. Some 42 vessels were constructed to the individual designs of their builders to meet Admiralty specifications, the only uniting feature being a specified top speed of . In fact the initial six vessels were generally differentiated by a slightly lower speed and were often referred to as "26-knotters" to distinguish them from the following batch of thirty-six vessels; all fifteen surviving "27-knotter" vessels were classified by the Admiralty as the A class in 1913 to provide some system to the naming of HM destroyers. All of the "26-knotters" and most of the "27-knotters" had been lost or scrapped before the 1913 classification (and so – strictly speaking – never survived to become 'A' class), but for convenience all 42 ships are listed below. The number of funnels varied from one to four. All vessels had a distinctive "turtleback" foreca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birkenhead
Birkenhead () is a town in the Metropolitan Borough of Wirral, Merseyside, England. The town is on the Wirral Peninsula, along the west bank of the River Mersey, opposite Liverpool. It lies within the Historic counties of England, historic county boundaries of Cheshire, and became part of Merseyside in 1974. At the 2021 United Kingdom census, 2021 census, the built up area as defined by the Office for National Statistics had a population of 109,835. Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution, leading to a shipbuilding firm which became Cammell Laird. A Great Float, seaport was established. As the town grew, Birkenhead Park and Hamilton Square were laid out. The first street tramway in Britain was built, followed by the Mersey Railway which connected Birkenhead and Liverpool through the world's first railway tunnel beneath a tidal estuary. In the sec ...

Palmers Shipbuilding And Iron Company Limited
Palmers Shipbuilding and Iron Company Limited, often referred to simply as "Palmers", was a United Kingdom of Great Britain and Ireland, British shipbuilder, shipbuilding company. The company was based in Jarrow, County Durham, in north-eastern England, and had operations in Hebburn and Willington Quay on the River Tyne. History Early history and growth The company was established in 1852 by Sir Charles Palmer, 1st Baronet, Charles Mark Palmer as Palmer Brothers & Co. in Jarrow. Later that year it launched the ''John Bowes (Steamship), John Bowes'', the first Screw steamer, iron screw Collier (ship type), collier. By 1900, the business was known as Palmers Shipbuilding and Iron Company. At that time, besides building ships, it manufactured and processed its own steel and other metals, and its products included Reed water tube boilers and marine steam engines. By 1902, Palmers' base at Jarrow occupied about 100 acres (41 hectares) and included 0.75 miles (1.2&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fife Ness
Fife Ness () is a headland forming the most eastern point in Fife, Scotland. Anciently the area was called Muck Ross, which is a corruption of the Scottish Gaelic ''Muc-Rois'' meaning "Headland of the Pigs". It is situated in the area of Fife known as the East Neuk, and forms the muzzle of the dog-like outline of the latter when viewed on a map. ''Ness'' is a Scots (language), Scots word meaning "headland". Fife Ness was home to a Her Majesty's Coastguard, Coastguard station until 2012 and an important Northern Lighthouse Board lighthouse built in 1975 on project by P. H. Hyslop, warning shipping of the headland and the North Carr shoals. The lighthouse was built to replace the last in a series of lightvessels that guarded the treacherous rocks, as it had proved impossible to build a permanent lighthouse on the rocks themselves. Fife Ness is also surrounded by the links terrain of Crail Golfing Society. See also * List of lighthouses in Scotland * List of Northern Lighthouse ...

Sunderland, Tyne And Wear
Sunderland () is a port City status in the United Kingdom, city and metropolitan borough in Tyne and Wear, England. It is a port at the mouth of the River Wear on the North Sea, approximately south-east of Newcastle upon Tyne. It is the most populous settlement in the Wearside conurbation and the second most populous settlement in North East England after Newcastle. Sunderland was once known as 'the largest shipbuilding town in the world' and once made a quarter of all of the world's ships from its famous yards, which date back to 1346 on the River Wear. The centre of the modern city is an amalgamation of three settlements founded in the Anglo-Saxons, Anglo-Saxon era: Monkwearmouth, on the north bank of the Wear, and Sunderland and Bishopwearmouth on the south bank. Monkwearmouth contains St Peter's Church, Monkwearmouth, St Peter's Church, which was founded in 674 and formed part of Monkwearmouth–Jarrow Abbey, a significant centre of learning in the seventh and eighth cent ...

William Doxford & Sons
William Doxford & Sons Ltd, often referred to simply as Doxford, was a United Kingdom of Great Britain and Ireland, British shipbuilder, shipbuilding and marine engineering company. History William Doxford founded the company in 1840. From 1870 it was based in Pallion, City of Sunderland, Sunderland, on the River Wear in England, Northeast England. The Company was managed by William Doxford's four sons following his death in 1882. It was acquired by Northumberland Shipbuilding Company in 1918. It was renamed ''Doxford & Sunderland Shipbuilding & Engineering Co Ltd'' in 1961 and ''Doxford & Sunderland Ltd'' in 1966. Court Line took it over in 1972 and renamed it ''Sunderland Shipbuilders Ltd''. In the 1970s a new all-weather Pallion yard was built which could build two ships of up to 30,000 tons deadweight side-by-side. The steel came in at one end, and the completed ship left from the other with engines installed and sometimes with the machinery running. Court Line collapse ...

Quarterdeck
The quarterdeck is a raised deck behind the main mast of a sailing ship. Traditionally it was where the captain commanded his vessel and where the ship's colours were kept. This led to its use as the main ceremonial and reception area on board, and the word is still used to refer to such an area on a ship or even in naval establishments on land. Many such facilities have areas decorated like shipboard quarterdecks. In the 20th century the word came to be applied to the area at the stern of the ship, often (on naval vessels) used for secondary weapons and (on battleships) seaplane catapults. Ceremonial use There are ancient traditions of offering special deference to the quarterdeck. Greek, Roman, and Carthaginian warships all carried shrines which were given special respect. This continued into Christian times, and in medieval British warships, the religious shrine was set up on the quarterdeck. All hands were required to salute it by taking off their hats or caps.

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armoured, from which an officer in charge can conn (nautical), conn (conduct or control) the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as is practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruiser, armoured cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield j ...

Reciprocating Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, e ...

Steam Turbine
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work utilising a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884. It revolutionized marine propulsion and navigation to a significant extent. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The largest steam turbine ever built is the 1,770 MW Arabelle steam turbine built by Arabelle Solutions (previously GE Steam Power), two units of which will be installed at Hinkley Point C Nuclear Power Station, England. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity. Some iron and steel-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engine
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...
