Doris Miller
Doris Miller (October 12, 1919November 24, 1943) was a United States Navy cook third class who was killed in action during World War II. He was the first Black American to be awarded the Navy Cross, the highest decoration for valor presented by the US Navy, and the second highest in the United States after the Medal of Honor. Miller served aboard the battleship , which was sunk by Japanese torpedo bombers during the surprise attack on Pearl Harbor on December 7, 1941. During the attack, he helped several sailors who were wounded, and while manning an Anti-aircraft warfare, anti-aircraft machine gun for which he had no training, he shot down 4-6 Japanese planes. Miller's actions earned him the medal, and the resulting publicity for Miller in the Black press made him an iconic emblem of the fight for civil rights for Black Americans. In November 1943, Miller was killed while serving aboard the escort carrier when it was sunk by a Japanese submarine during the Battle of Makin in th ...

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 ...

Amidships
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water (mostly though not necessarily on the sea). Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin ''nauticus'', from Greek ''nautikos'', from ''nautēs'': "sailor", from ''naus'': "ship". Further information on nautical terminology may also be found at Nautical metaphors in English, and additional military terms are listed in the Multiservice tactical brevity code article. Terms used in other fields associated with bodies of water can be found at Glossary of fishery terms, Glossary of underwater diving terminology, Glossary of rowing terms, and Glossary of meteorology. This glossary is split into two articles: * terms starting with the letters A to L are at Glossary of nautical terms (A-L) * terms starting with the letters M to Z are at Glossary of nautical terms (M-Z). __N ...

Gyrodyne QH-50
The Gyrodyne QH-50 DASH (''Drone Anti-Submarine Helicopter'') is a small drone helicopter built by Gyrodyne Company of America for use as a long-range anti-submarine weapon on ships that would otherwise be too small to operate a full-sized helicopter. It remained in production until 1969. Several are still used today for various land-based roles. Design and development DASH was a major part of the United States Navy's Fleet Rehabilitation and Modernization (FRAM) program of the late 1950s. FRAM was started because the Soviet Union was building submarines faster than the US could build anti-submarine frigates. Instead of building frigates, the FRAM upgrade series allowed the US to rapidly update by converting older ships that were less useful in modern naval combat. The navy could upgrade the sonar on World War II-era destroyers but needed a stand-off weapon to attack at the perimeter of the sonar's range. The old destroyers had little room for add-ons such as a full flight d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 32 Surface Vessel Torpedo Tubes
Mark 32 Surface Vessel Torpedo Tubes (Mk 32 SVTT) is a torpedo launching system designed for the United States Navy. History The Mark 32 has been the standard anti-submarine torpedo launching system aboard United States Navy surface vessels since its introduction in 1960, and is in use aboard the warships of several other navies. During the FRAM Program, , and destroyers were modernized and fitted with two Mark 32 torpedo tubes on each side of their midship. The torpedo tubes' service extended to multiple other countries such as Mexico, South Korea, Taiwan, Turkey, Egypt and many more due to the fact that decommissioned American ships were bought or transferred over to them throughout the years, notably s. Japan uses the HOS-301 torpedo tubes which are redesignated version of the Mark 32. Design Most versions (referred to as modifications or mods) are triple-tube sets that can be rotated or trained to face a target. The exception is the Mod 9 sets, which only have two ...

3-inch/50-caliber Gun
The 3"/50 caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through to 1994 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3"/50 caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Merchant Ships.

Boiler
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 common ...

Combustion Engineering
Combustion Engineering (C-E) was a multi-national American-based engineering firm that developed nuclear steam supply power systems in the United States. Originally headquartered in New York City, C-E moved its corporate offices to Stamford, Connecticut in 1973. C-E owned over three dozen other companies including Lummus Company, National Tank Company and the Morgan Door Company. The company was acquired by Asea Brown Boveri in early 1990. The boiler and fossil fuel businesses were purchased by Alstom in 2000, and the nuclear business was purchased by Westinghouse Electric Company also in 2000. History Founding Combustion Engineering was organized in 1912 through the merger of the Grieve Grate Company and the American Stoker Company, two well-known manufacturers of fuel burning equipment. The company was originally headquartered on 11 Broadway and at 43 ''-'' 5 ''-'' 7 Broad Street (Manhattan), both in Lower Manhattan. The city block was leased from the Alliance Realty Compa ...

Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westinghouse Combustion Turbine Systems Division
The Westinghouse Combustion Turbine Systems Division (CTSD), part of Westinghouse Electric Corporation's Westinghouse Power Generation group, was originally located, along with the Steam Turbine Division (STD), in a major industrial manufacturing complex, referred to as the South Philadelphia Works, in Lester, PA near to the Philadelphia International Airport. Before first being called "CTSD" in 1978, the Westinghouse industrial and electric utility gas turbine business operation progressed through several other names starting with Small Steam & Gas Turbine Division (SSGT) in the 1950s through 1971, then Gas Turbine Systems Division (GTSD) and Generation Systems Division (GSD) through the mid-late 1970s. The name CTSD came with the passage of energy legislation by the US government in 1978 which prohibited electric utilities from building new base load power plants that burned natural gas. Some participants in the industry decided to use the name "combustion turbine" in an attempt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
