NMS Elisabeta
NMS ''Elisabeta'' was a small protected cruiser built for the Romanian Navy during the 1880s by Armstrong in Britain as Romania lacked the ability to build the ship itself. Serving mainly as a training ship, she represented Romania at the opening of the Kiel Canal in 1895. She helped protect Romanian interests in Constantinople during the First Balkan War in 1912–1913, but played no significant part in the Second Balkan War and was partially disarmed during World War I. Employed as a barracks ship after the war, the ship was scrapped in 1926. Description ''Elisabeta'' was built of steel and measured long overall.Brook, p. 69 She had a beam of and a draft at the bow of that increased to at the stern. She displaced at full load.Georgescu, p. 167 The ship had a crew of 140 officers and crewmen. ''Elisabeta'' had two vertical triple-expansion steam engines, each driving a single screw propellers. Four cylindrical boilers provided steam to the engines. The engines had a desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elisabeth Of Wied
Pauline Elisabeth Ottilie Luise of Wied (29 December 18432 March 1916) was the first queen of Romania as the wife of King Carol I from 15 March 1881 to 27 September 1914. She had been the princess consort of Romania since her marriage to then-Prince Carol on 15 November 1869. Elisabeth was born into a German noble family. She was briefly considered as a potential bride for the future British king Edward VII, but Edward rejected her. Elisabeth married Prince Carol of Romania in 1869. Their only child, Princess Maria, died aged three in 1874, and Elisabeth never fully recovered from the loss of her daughter. When Romania became a kingdom in 1881, Elisabeth became queen, and she was crowned together with Carol that same year. Elisabeth was a prolific writer under the name Carmen Sylva. Family and early life Born at Castle Monrepos in Neuwied, she was the daughter of Hermann, Prince of Wied, and his wife Princess Marie of Nassau. Elisabeth had artistic leanings; her childhood ...

Romania
Romania ( ; ro, România ) is a country located at the crossroads of Central Europe, Central, Eastern Europe, Eastern, and Southeast Europe, Southeastern Europe. It borders Bulgaria to the south, Ukraine to the north, Hungary to the west, Serbia to the southwest, Moldova to the east, and the Black Sea to the southeast. It has a predominantly Temperate climate, temperate-continental climate, and an area of , with a population of around 19 million. Romania is the List of European countries by area, twelfth-largest country in Europe and the List of European Union member states by population, sixth-most populous member state of the European Union. Its capital and largest city is Bucharest, followed by Iași, Cluj-Napoca, Timișoara, Constanța, Craiova, Brașov, and Galați. The Danube, Europe's second-longest river, rises in Germany's Black Forest and flows in a southeasterly direction for , before emptying into Romania's Danube Delta.

Forced Draft
The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow. Types of draft Drafts are produced by the rising combustion gases in the stack, flue, or by mechanical means. For example, a boiler can be put into four categories: natural, induced, balanced, and forced. *Natural draft: When air or flue gases flow due to the difference in density of the hot flue gases and cooler ambient gases. The difference in density creates a pressure differential that moves the hotter flue gases into the cooler surroundings. * Forced draft: When air or flue gases are maintained above atmospheric pressure. Normally it is done with the help of a forced draft fan. * Induced draft: When air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric p ...

Chimney Draught
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the ''flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term ''smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of a chimn ...

Screw Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Draft (ship)
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] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Barracks Ship
A barracks ship or barracks barge or berthing barge, or in civilian use accommodation vessel or accommodation ship, is a ship or a non-self-propelled barge containing a superstructure of a type suitable for use as a temporary barracks for sailors or other military personnel. A barracks ship, a military form of a dormitory ship, may also be used as a receiving unit for sailors who need temporary residence prior to being assigned to their ship. The United States Navy used to call them Yard Repair Berthing and Messing with designations YRBM and YRBM(L) and now classes them as either Auxiliary Personnel Barracks (APB) or Auxiliary Personnel Lighter (aka barge) (APL). Early use Barrack ships were common during the era of sailing ships when shore facilities were scarce or non-existent. Barrack ships were usually hulks. At times, barrack ships were also used as prison ships for convicts, prisoners of war or civilian internees. Use in World War II ''Barracks ships'' in the comb ...

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 Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Balkan War
The Second Balkan War was a conflict which broke out when Bulgaria, dissatisfied with its share of the spoils of the First Balkan War, attacked its former allies, Serbia and Greece, on 16 ( O.S.) / 29 (N.S.) June 1913. Serbian and Greek armies repulsed the Bulgarian offensive and counter-attacked, entering Bulgaria. With Bulgaria also having previously engaged in territorial disputes with Romania and the bulk of Bulgarian forces engaged in the south, the prospect of an easy victory incited Romanian intervention against Bulgaria. The Ottoman Empire also took advantage of the situation to regain some lost territories from the previous war. When Romanian troops approached the capital Sofia, Bulgaria asked for an armistice, resulting in the Treaty of Bucharest, in which Bulgaria had to cede portions of its First Balkan War gains to Serbia, Greece and Romania. In the Treaty of Constantinople, it lost Adrianople to the Ottomans. The political developments and military preparations f ...

First Balkan War
The First Balkan War ( sr, Први балкански рат, ''Prvi balkanski rat''; bg, Балканска война; el, Αʹ Βαλκανικός πόλεμος; tr, Birinci Balkan Savaşı) lasted from October 1912 to May 1913 and involved actions of the Balkan League (the Kingdoms of Kingdom of Bulgaria, Bulgaria, Kingdom of Serbia, Serbia, Kingdom of Greece, Greece and Kingdom of Montenegro, Montenegro) against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior (significantly superior by the end of the conflict) and strategically disadvantaged Ottoman armies, achieving rapid success. The war was a comprehensive and unmitigated disaster for the Ottomans, who lost 83% of their European territories and 69% of their European population.
