Light Airborne Multi-Purpose System
The Light Airborne Multi-Purpose System (LAMPS) is the United States Navy's program that develops crewed helicopters to assist the surface fleet in anti-submarine warfare. The purpose of LAMPS is to scout outside the limits of a fleet's radar and sonar range to detect and track enemy submarines or missile-equipped escort ships and feed the real-time data back to their LAMPS mothership. They also have the capability to directly engage enemy targets with depth charges or torpedoes, or indirectly engage the enemy by coordinating fleet assets on site. A Mk II version was planned, but was canceled in favor of the more advanced Mk III. LAMPS III added the capabilities to use anti-ship missile systems (like the AGM-119 Penguin anti-ship missile) and night vision capability. History In October 1970, the UH-2 was selected to be the platform to function as the interim Light Airborne Multi-Purpose System (LAMPS) helicopter.Frawley 2002, p. 100. During the course of the 1960s, LAM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaman SH-2 Seasprite
The Kaman SH-2 Seasprite is a ship-based helicopter originally developed and produced by American manufacturer Kaman Aircraft Corporation. It has been typically used as a compact and fast-moving rotorcraft for utility and anti-submarine warfare missions. Development of the Seasprite had been initiated during the late 1950s in response to a request from the United States Navy, calling for a suitably fast and compact naval helicopter for utility missions. Kaman's submission, internally designated as the ''K-20'', was favourably evaluated, leading to the issuing of a contract for the construction of four prototypes and an initial batch of 12 production helicopters, designated as the ''HU2K-1''. Under the 1962 United States Tri-Service aircraft designation system, the HU2K was redesignated H-2, the HU2K-1 becoming the UH-2A. Beyond the U.S. Navy, the company had also made efforts to acquire other customers for export sales, in particular the Royal Canadian Navy; however, the i ...

5"/54 Caliber Mark 42 Gun
The Mark 42 5"/54 caliber gun (127mm) is a naval gun (naval artillery) mount used by the United States Navy and other countries. It consisted of the Mark 18 gun and Mark 42 gun mount. United States naval gun terminology indicates the gun fires a projectile in diameter, and the barrel is 54 calibers long (barrel length is 5" × 54 = 270" or 6.9 meters.) In the 1950s a gun with more range and a faster rate of fire than the 5"/38 caliber gun used in World War II was needed, therefore, the gun was created concurrently with the 3"/70 Mark 26 gun for different usages. The 5"/54 Mk 42 is an automatic, dual-purpose (air / surface target) gun mount. It is usually controlled remotely from the Mk 68 Gun Fire Control System, or locally from the mount at the One Man Control (OMC) station. The self-loading gun mount weighs about including two drums under the mount holding 40 rounds of semi-fixed case type ammunition. The gun fires projectiles at a velocity of .Baile ...

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 ...

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 Com ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A ...

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 ... [...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 In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...
