SP-350 Denise
The SP-350 ''Denise'', famous as the "Diving saucer" (''Soucoupe plongeante''), is a small submarine designed to hold two people, and is capable of exploring depths of up to . It was invented by Jacques-Yves Cousteau and engineer Jean Mollard at the French Centre for Undersea Research. It was built in the year 1959 and usually operated from Cousteau's ship, the '' Calypso''. Diving Saucer Specifications ''Denise''s propulsion consists of steerable, electrically powered water jets, allowing it to navigate in all directions, as well as turn about its vertical axis. To correct the attitude of the hull, the pilot can shift a liquid mercury ballast mass. The crew members enter the craft through a hatch on the top of the hull and lie prone side-by-side on mattresses to operate it, watching their surroundings through tilted portholes that let them come within a few centimeters of their subject. Electric lamps are fitted for night diving and to provide illumination for photography at ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Jacques-Yves Cousteau
Jacques-Yves Cousteau, (, also , ; 11 June 191025 June 1997) was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful Aqua-Lung, open-circuit SCUBA (self-contained underwater breathing apparatus). The apparatus assisted him in producing some of the first underwater documentaries. Cousteau wrote many books describing his undersea explorations. In his first book, ''The Silent World: A Story of Undersea Discovery and Adventure'', Cousteau surmised the existence of the Animal echolocation, echolocation abilities of porpoises. The book was adapted into an underwater documentary called ''The Silent World''. Co-directed by Cousteau and Louis Malle, it was one of the first films to use underwater photography, underwater cinematography to document the ocean depths color photography, in color. The film won the 1956 Palme d'Or at the Cannes Film Festival and remained the only documentary to do so until 2004, when ''Fahrenheit 9/11'' received the ...

Pump-jet
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.http://www.hamiltonmarine.co.nz/includes/files_cms/file/JetTorque%2008.pdf Design A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle. With the use of a ''reversing bucket'', reverse thrust can also be achieved for faring backwards, quickly and withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Ballast
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ballast "did not cons ...

Crane (machine)
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later developed in the Roman Empire, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Without Sun
''World Without Sun'' (french: Le Monde sans soleil) is a 1964 French documentary film directed by Jacques-Yves Cousteau. The film was Cousteau's second to win an Academy Award for Best Documentary Feature, following ''The Silent World'' in 1956. Content The film chronicles Continental Shelf Station Two, or "Conshelf Two", the first ambitious attempt to create an environment in which men could live and work on the seafloor. In it, a half-dozen oceanauts lived 10 meters down in the Red Sea off Sudan in a star-fish shaped house for 30 days. The undersea living experiment also had two other structures, one a submarine hangar that housed a small, two-man submarine referred to as the "diving saucer" for its resemblance to a science fiction flying saucer, and a smaller "deep cabin" where two oceanauts lived at a depth of 30 meters for a week. The undersea colony was supported by air, water, food, power, all essentials of life, from a large support team above. Men on the bottom perform ...

HMHS Britannic
''Britannic'' () was the third and final vessel of the White Star Line's of steamships and the second White Star ship to bear the name ''Britannic''. She was the youngest sister of the and the and was intended to enter service as a transatlantic passenger liner. She was operated as a hospital ship from 1915 until her sinking near the Greek island of Kea, in the Aegean Sea, in November 1916. At the time she was the largest hospital ship in the world. ''Britannic'' was launched just before the start of the First World War. She was designed to be the safest of the three ships with design changes made during construction due to lessons learned from the sinking of the ''Titanic''. She was laid up at her builders, Harland and Wolff, in Belfast for many months before being requisitioned as a hospital ship. In 1915 and 1916 she served between the United Kingdom and the Dardanelles. On the morning of 21 November 1916 she was shaken by an explosion caused by a naval mine of the Im ...

Deep Star 4000
''Deepstar 4000'' was a U.S. Navy/civilian deep-submergence vehicle designed by Jacques Cousteau and built by Westinghouse. It was built in 1965 and retired in 1972. Some of the explorations of ''Deepstar 4000'' were shown in the January 1971 edition of ''National Geographic''. At the time of the article, ''Deepstar 4000'' had already completed more than 200 dives in the Atlantic, Pacific, and Caribbean. This number of completed dives appears to be understated. In R. Frank Busby's book ''Manned Submersibles'', it is stated on page 53 that the ''Deepstar 4000'' "conducted some 500 dives from June 1966 through June 1968". ''Deepstar 4000'' was designed to take a crew of up to three to a depth of , hence the name ''Deepstar 4000''. History The U.S. Naval Oceanographic Office used ''Deepstar 4000'' for 13 dives during October and November 1967. Marine geology, biology and the physical properties of the water column were studied on the 10 deep dives of this series. These dives were a ...

Research Submarines Of France
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
