HMS Raven II
HMS ''Raven II'' was a seaplane carrier of the Royal Navy used during the First World War. Converted from the captured German freighter ''Rabenfels'', the ship's aircraft conducted aerial reconnaissance, observation and bombing missions in the Eastern Mediterranean and Red Sea during 1915–17 even though the ship was not commissioned into the Royal Navy until mid-1915. She fruitlessly searched the Indian Ocean for the German commerce raider in mid-1917. ''Raven II'' was decommissioned in late 1917 and became a Merchant Navy collier for the last year of the war. She was sold off in 1923 and had a succession of owners and names until she was sunk during the Second World War while under Japanese ownership. Description ''Raven II'' was long, had a beam of , and a draught of .Layman, p. 41 She was rated at 4,706 GRT. The ship had one propeller shaft powered by one quadruple-expansion steam engine that used steam generated by an unknown number of coal-fired boilers. ''Raven I ...

Swan Hunter & Wigham Richardson
Swan Hunter, formerly known as Swan Hunter & Wigham Richardson, is a shipbuilding design, engineering, and management company, based in Wallsend, Tyne and Wear, England. At its apex, the company represented the combined forces of three powerful shipbuilding families: Swan, Hunter and Wigham Richardson. The company was responsible for some of the greatest ships of the early 20th century, most famously which held the Blue Riband for the fastest crossing of the Atlantic, and which rescued survivors from . In 2006 ''Swan Hunter'' ceased vessel construction on Tyneside, but continues to provide design engineering services. History Swan & Hunter was founded by George Burton Hunter, who formed a partnership with the widow of Charles Sheridan Swan (the owner of a Wallsend Shipbuilding business established in 1852 by Charles Mitchell (shipbuilder), Charles Mitchell) under the name in 1880. In 1903, C.S. Swan & Hunter merged with Wigham Richardson (founded by John Wigham Richards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commerce Raider
Commerce raiding (french: guerre de course, "war of the chase"; german: Handelskrieg, "trade war") is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them. Privateering The first sort of commerce raiding was for nations to commission privateers. Early instances of this type of warfare were by the English and Dutch against the Spanish treasure fleets of the 16th century, which resulted in financial gain for both captain and crew upon capture of enemy vessels ("prizes"). 17th and 18th centuries Privateers formed a large part of the total military force at sea during the 17th and 18th centuries. In the First Anglo-Dutch War, English privateers attacked the trade on which the United Provinces entirely depended, capturing over 1,000 Dutch merchant ships. During the subsequent war with Spain, Spanish and Flemish privateers in the service ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Type 184
The Short Admiralty Type 184, often called the Short 225 after the power rating of the engine first fitted, was a British two-seat reconnaissance, bombing and torpedo carrying folding-wing seaplane designed by Horace Short of Short Brothers. It was first flown in 1915 and remained in service until after the armistice in 1918. A Short 184 was the first aircraft to sink a ship using a torpedo, and another was the only British aircraft to take part in the Battle of Jutland. Design and development Torpedo-dropping trials had been undertaken using a Gnome powered Short Admiralty Type 166 but this had proved insufficiently powerful, and so in September 1914 a new specification was formulated for an aircraft to be powered by the Sunbeam Mohawk engine currently being developed. Design proposals were invited from Sopwith, J. Samuel White and Short Brothers. Horace Short's response when the requirements were explained him by Murray Sueter, the director of the naval air department, wa ...

Floatplane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nieuport VI
The Nieuport VI was a sport monoplane produced in France in the 1910s, a further development by Nieuport along the same general lines as the Nieuport II and Nieuport IV, differing mainly from the Nieuport IV in being slightly larger.Taylor 1989, p.696''The Illustrated Encyclopedia of Aircraft'', p.2597 Like the Nieuport IV, it was used by various military air arms as a reconnaissance aircraft and trainer. Design and development Like its predecessors, the Nieuport VI was a wire-braced, mid-wing monoplane of conventional design, powered by a single engine in the nose driving a tractor propeller. It differed, however, in being a three-seater rather than a single seater (a bench for two passengers fitted in tandem with the pilot's seat) and in using steel for part of its internal structure where earlier designs had used wood only.Sanger 2002, p.25 Produced initially as a seaplane and designated VI.G, it had twin pontoons as undercarriage, with a teardrop-shaped auxiliary float under ...

Seaplanes
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplan ...

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Said
Port Said ( ar, بورسعيد, Būrsaʿīd, ; grc, Πηλούσιον, Pēlousion) is a city that lies in northeast Egypt extending about along the coast of the Mediterranean Sea, north of the Suez Canal. With an approximate population of 603,787 (2010), it is the List of cities and towns in Egypt, fifth-largest city in Egypt. The city was established in 1859 during the building of the Suez Canal. There are numerous old houses with grand balconies on all floors, giving the city a distinctive look. Port Said's twin city is Port Fuad, which lies on the eastern bank of the Suez Canal. The two cities coexist, to the extent that there is hardly any town centre in Port Fuad. The cities are connected by free Ferry, ferries running all through the day, and together they form a metropolitan area with over a million residents that extends both on the African and the Asian sides of the Suez Canal. The only other metropolitan area in the world that also spans two continents is Istanbul. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in hu ...

Boiler (steam Generator)
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is com ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
