British A Class Submarine (1903)
The A class was the Royal Navy's first class of British-designed submarines. Thirteen were built by Vickers at Barrow-in-Furness between 1902 and 1905 as an improvement on the US . Design and construction While there was considerable variation amongst the boats of the class, they were around long and displaced around 200 tons when submerged. The first, ''A1'' (ordered as ''Holland No. 6''), was launched in July 1902, the last, ''A13'', in April 1905. Propulsion All were propelled underwater by battery-powered electric motors and on the surface by shaft-drive Wolseley petrol engines of (''A1''), (''A2-A4'') or (''A5''-''A12''). ''A13'' had an experimental Vickers diesel engine, which proved to be unreliable. Armaments Armament was two torpedo tubes with four torpedoes except for ''A1'', which had 1 tube and 3 torpedoes. Service history This submarine class was plagued by numerous accidents and failures; almost every boat in the class (''A1'', ''A3'', ''A4'' ...

Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.

Ardrossan
Ardrossan (; ) is a town on the North Ayrshire coast in southwestern Scotland. The town has a population of 10,670 and forms part of a conurbation with Saltcoats and Stevenston known as the ' Three Towns'. Ardrossan is located on the east shore of the Firth of Clyde. History Ardrossan's roots can be traced to the construction of its castle 'Cannon Hill', thought to be in around 1140, by Simon de Morville. The castle and estate passed to the Barclay family (also known as Craig) and through successive heirs until the 14th century when it passed to the Eglinton family on the death of Godfrey Barclay de Ardrossan, who died without an heir. Sir Fergus Barclay, Baron of Ardrossan, was said to be in league with the Devil and in one of his dealings, set the task for the Devil to make ropes from sand; on failing to do so, the Devil kicked the castle with his hoof in frustration and left a petrosomatoglyph hoofprint.Ardrossan & Neighbourhood.

HMNB Devonport
His Majesty's Naval Base, Devonport (HMNB Devonport) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Portsmouth) and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest naval base in Western Europe, HMNB Devonport is located in Devonport, in the west of the city of Plymouth, England. The base began as Royal Navy Dockyard in the late 17th century, but shipbuilding ceased at Devonport in the early 1970s, although ship maintenance work has continued. The now privatised maintenance facilities are operated by Babcock International Group, who took over the previous owner Devonport Management Limited (DML) in 2007. DML had been running the Dockyard since privatisation in 1987. From 1934 until the early 21st century the naval barracks on the site was named HMS ''Drake'' (it had previously been known as HMS ''Vivid'' after the base ship of the same name). The name HMS ''Drake'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitsand Bay
Whitsand Bay, situated in south east Cornwall, England, runs from Rame Head in the east to Portwrinkle in the west. It is characterised by sheer, high cliffs, dramatic scenery and long stretches of sandy beaches. The South West Coast Path runs the length of the bay. Geography The bay is overlooked by Rame Head, a conical hill with the ruins of a 14th-century chapel dedicated to St Michael on top. Polhawn Cove is a rough beach, consisting of sharp rocks, shingle and an area of open sand. West of Captain Blake's Point, long stretches of sand are interspersed with rocky headlands and small bays, many inaccessible at high tide. The holiday settlements of Freathy and Tregonhawke are built on terraces on the cliff faces. A National Trust property at Sharrow Point preserves a small cave excavated by hand in 1874 by a hermit called Lugger, who inscribed verses on the ceiling to relieve his boredom. Lugger's Cave is fenced off to the public. The headland forms part of '' Rame Head ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portsmouth
Portsmouth ( ) is a port and city in the ceremonial county of Hampshire in southern England. The city of Portsmouth has been a unitary authority since 1 April 1997 and is administered by Portsmouth City Council.

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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrol
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

Wolseley Motors
Wolseley Motors Limited was a British motor vehicle manufacturer founded in early 1901 by the Vickers Armaments in conjunction with Herbert Austin. It initially made a full range, topped by large luxury cars, and dominated the market in the Edwardian era. The Vickers brothers diedin 1914 and 1919 respectively and, without their guidance, Wolseley expanded rapidly after the war, manufacturing 12,000 cars in 1921, and remained the biggest motor manufacturer in Britain. Over-expansion led to receivership in 1927 when it was bought from Vickers Limited by William Morris as a personal investment. He moved it into his Morris Motors empire just before the Second World War. After that, Wolseley products were "badge-engineered" Morris cars. Wolseley went with its sister businesses into BMC, BMH and British Leyland, where its name lapsed in 1975.

A Class Submarines
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...
