Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, Instantaneous stability, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outrigger boat, outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. ...

Costa Concordia Disaster
On 13 January 2012, the seven-year-old Costa Cruises vessel ''Costa Concordia'' was on the first leg of a cruise around the Mediterranean Sea when it deviated from its planned route at Isola del Giglio, Tuscany in order to perform a sail-by salute, sailed closer to the island than intended, and struck a rock formation on the sea floor. This caused the ship to angle of list, list and then to partially sink, landing unevenly on an underwater ledge. Although a six-hour rescue effort brought most of the passengers ashore, 32 people died: 27 passengers and five crew. A member of the salvage team also died following injuries received during the recovery operation. An investigation focused on shortcomings in the procedures followed by ''Costa Concordia'' crew and the actions of her captain, Francesco Schettino, who The captain goes down with the ship#Counter-examples, left the ship prematurely. He left about 300 passengers on board the sinking vessel, most of whom were rescued by hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Camel
A ship camel is an external flotation tank that can be fitted to a ship to increase her buoyancy or reduce her draught. Its inner walls may be concave and curve to fit the hull of the ship. The ship camels are partially sunk using water ballast, fitted to the ship in opposed pairs, and the water is then pumped out again. The increased displaced volume provided by the camels allows the system to float at a reduced draught. History The ship camel was invented in 1690 by the Dutchman Meeuwis Meindertsz Bakker to allow large ships of the line to cross shallow banks that isolated the harbour of Amsterdam from the open sea. In April, he tested the device with the large ship of the line ''Princess Maria'', which was sailed over the shallow waters of Pampus in the Zuiderzee. The Admiralty of Amsterdam rewarded Bakker for his invention. The camel was mostly used in the Dutch Golden Age for accessing the shallow waters at Pampus, which were unreachable for large merchant ships. Inste ...

Pan Am Clipper
Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. The first airline to fly worldwide, it pioneered innovations such as Wide-body aircraft, jumbo jets and computerized reservation systems, and introduced the Boeing 707, first American jetliner in 1958. Until its dissolution on December 4, 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. In the 1930s, under the le ...

Shipbuilding
Shipbuilding is the construction of ships and other Watercraft, floating vessels. In modern times, it normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Until recently, with the development of complex non-maritime technologies, a ship has often represented the most advanced structure that the society building it could produce. Some key industrial advances were developed to support shipbuilding, for instance the sawing of timbers by Saw#Mechanically powered saws, mechanical saws propelled by windmills in Dutch shipyards during the first half of the 17th century. The design process saw the early adoption of the logarithm (invented in 1615) to generate the curves used to produce the shape of a hull (watercraft), hull, especially when scaling up these curves accurately in the mould Lofting, loft. Shipbuilding and ship repairs, both commercial an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-torpedo Bulge
The anti-torpedo bulge (also known as an anti-torpedo blister) is a form of defence against naval torpedoes occasionally employed in warship construction in the period between the First and Second World Wars. It involved fitting (or retrofitting) partially water-filled compartmentalized sponsons on either side of a ship's hull, intended to detonate torpedoes, absorb their explosions, and contain flooding to damaged areas within the bulges. Application Essentially, the bulge is a compartmentalized, below the waterline sponson isolated from the ship's internal volume. It is part air-filled, and part free-flooding. In theory, a torpedo strike will rupture and flood the bulge's outer air-filled component while the inner water-filled part dissipates the shock and absorbs explosive fragments, leaving the ship's main hull structurally intact. Transverse bulkheads within the bulge limit flooding to the damaged area of the structure. The bulge was developed by the British Director of ...

Casemate
A casemate is a fortified gun emplacement or armoured structure from which guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see .) In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a protected space for guns in a ship, either within the hull or in the low ...

Princess Of Scandinavia Gothenburg
Princess is a title used by a female member of a regnant monarch's family or by a female ruler of a principality. The male equivalent is a prince (from Latin ''princeps'', meaning principal citizen). Most often, the term has been used for the consort of a prince, or for the daughter of a monarch. A crown princess can be the heir apparent to the throne or the spouse of the heir apparent. Princess as a substantive title Some princesses are reigning monarchs of principalities. There have been fewer instances of reigning princesses than reigning princes, as most principalities excluded women from inheriting the throne. An example of a princess regnant is Constance of Antioch, princess regnant of Antioch in the 12th century. Since the president of France, an office for which women are eligible, is ''ex-officio'' a co-prince of Andorra, then Andorra could theoretically be jointly ruled by a princess. Princess as a courtesy title Descendants of monarchs For many centuries, the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppelin-Lindau Rs
Luftschiffbau Zeppelin GmbH is a German aircraft manufacturing company. It is perhaps best known for its leading role in the design and manufacture of rigid airships, commonly referred to as '' Zeppelins'' due to the company's prominence. The name 'Luftschiffbau' is a German word meaning ''building of airships''. The company was founded by Count Ferdinand von Zeppelin in 1908 as a formal entity to continue advancing his pioneering research into rigid airships. ''Luftschiffbau Zeppelin'' became the leading manufacturer in the field of large lighter-than-air vehicles; its products were used in both military and civilian capacities. The firm founded DELAG, the world's first airline to use an aircraft in revenue service, in 1909 on the back of public interest and using its own airships. During the First World War, Zeppelins were employed as the first long distance strategic bombers, launching numerous raids upon Belgium, France, and the United Kingdom.
