C Class Destroyer (1913)
The C 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 of the class was a top speed of 30 knots, a "turtleback" forecastle and that they all had three funnels. The funnels were spaced equidistantly and were of equal height, but the central one was thicker. In 1913 all "30 knotter" vessels with 3 funnels were classified by the Admiralty as the "C" class to provide some system to the naming of HM destroyers (at the same time, the 4-funnelled, "30 knotters" became the "B" class and the 2-funnelled ships the "D" class). All vessels had the distinctive turtleback that was intended to clear water from the bows but actually tended to dig the bow in to anything of a sea, resulting in a very wet conning position and poor seaboats that were unable to reach top speed in anything but perfe ...

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" forecastle t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engine
A steam engine is a heat engine that performs 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. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines 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 boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunderland, Tyne And Wear
Sunderland () is a port city in Tyne and Wear, England. It is the City of Sunderland's administrative centre and in the historic county of Durham. The city is from Newcastle-upon-Tyne and is on the River Wear's mouth to the North Sea. The river also flows through Durham roughly south-west of Sunderland City Centre. It is the only other city in the county and the second largest settlement in the North East after Newcastle upon Tyne. Locals from the city are sometimes known as Mackems. The term originated as recently as the early 1980s; its use and acceptance by residents, particularly among the older generations, is not universal. At one time, ships built on the Wear were called "Jamies", in contrast with those from the Tyne, which were known as "Geordies", although in the case of "Jamie" it is not known whether this was ever extended to people. There were three original settlements by the River's mouth which are part of the modern-day city: Monkwearmouth, settled in 674 ...

William Doxford & Sons
William Doxford & Sons Ltd, often referred to simply as Doxford, was a British shipbuilding and marine engineering company. History William Doxford founded the company in 1840. From 1870 it was based in Pallion, Sunderland, on the River Wear in 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 collapsed in 1974 and the company was nationalised. It was privatised in 1986 when it was me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingston Upon Hull
Kingston upon Hull, usually abbreviated to Hull, is a port city and unitary authority in the East Riding of Yorkshire, England. It lies upon the River Hull at its confluence with the Humber Estuary, inland from the North Sea and south-east of York, the historic county town. With a population of (), it is the fourth-largest city in the Yorkshire and the Humber region after Leeds, Sheffield and Bradford. The town of Wyke on Hull was founded late in the 12th century by the monks of Meaux Abbey as a port from which to export their wool. Renamed ''Kings-town upon Hull'' in 1299, Hull had been a market town, military supply port, trading centre, fishing and whaling centre and industrial metropolis. Hull was an early theatre of battle in the English Civil Wars. Its 18th-century Member of Parliament, William Wilberforce, took a prominent part in the abolition of the slave trade in Britain. More than 95% of the city was damaged or destroyed in the blitz and suffered a perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earle's Shipbuilding
Earle's Shipbuilding was an engineering company that was based in Hull, East Riding of Yorkshire, England from 1845 to 1932. Earle Brothers The company was started in Hull in 1845 by two brothers, Charles and William Earle. The firm was made up of engineers and focussed on shipbuilding and repair. Its most notable association was with the Wilson Line, for whom the yard produced many ships. Earle's also built vessels for many other British shipping firms, especially those operating on North Sea routes such as the Great Eastern Railway and the Hull & Netherlands Steamship Co. Ltd. In 1871, Earle's was restructured as a joint-stock company and for a short time Sir Edward James Reed served as its chairman and managing director. Earle's built two steam yachts for Tsarevitch Alexander: ''Slavanka'' in 1873 and ''Czarevna'' in 1874. Also in 1874 Earle's built the unsuccessful , Sir Henry Bessemer's experimental swinging-cabin paddle steamer, which made its maiden (and only) publi ...

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. In modern military designs the stern has been roofed over by the helicopter deck but a large space remains underneath which is typically used for sonar equipment or small boats and which is still referred to as the quarterdeck in Commonwealth navies. Ceremonial use There are ancient traditions of offering special deference to the quarterdeck. Greek, Roman, and Carthaginian warships all c ...

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn 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 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 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 just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandstand
A bandstand (sometimes music kiosk) is a circular, semicircular or polygonal structure set in a park, garden, pier, or indoor space, designed to accommodate musical bands performing concerts. A simple construction, it both creates an ornamental focal point and also serves acoustic requirements while providing shelter for the changeable weather, if outdoors. In form bandstands resemble ornamental European garden gazebos modeled on outdoor open-sided pavilions found in Asian countries from early times. Origins During the 18th and 19th centuries this type of performance building was found in the fashionable pleasure gardens of London and Paris where musicians played for guests dining and dancing. They were later built in public spaces in many countries as practical amenities for outdoor entertainment. Many bandstands in the United Kingdom originated in the Victorian era as the British brass band movement gained popularity. Smaller bandstands are often not much more than gaze ...

Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically 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 intr ...
