Draft (hull)
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] |
Torpedo Boat Classes
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though some ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

Nasr-1
The Nasr-1 ( fa, نصر-۱) is an Iranian anti-ship cruise missile. According to its export catalog, it can destroy 1,500-tonne targets such as small frigates. Nasr-1 missile can be launched from both inland bases and offshore military vessels, and is being modified to be fired from helicopters and submarines. The missile has a cigarette shaped body with four large foldable fins attached to the middle part and four smaller ones attached to the end of the missile near the exhaust. In December 2008, an Iranian naval force successfully test-fired the surface-to-surface Nasr-1 during the final stage of "Unity 87" wargames in the Persian Gulf waters. Following the successful test firing, on 7 March 2010, Iran's defence minister announced mass-production of Nasr-1 missiles. In early 2012, during Velayet-e 90 wargames, it was tested from land-based TELs. On 10 February 2013, head of Iran Aviation Industries Organization announced that an air-launched version of Qader and Nasr-1 ant ...

Kowsar
Kowsar () is a medium-range, land-based anti-ship missile made by Iran. It can defeat electronic jamming systems and "cannot be thrown off course", according to Iranian officials. The Kowsar designation apparently (Missile Defense Advocacy Alliance 2006) is used to refer to two different missiles: Iranian-produced versions of the PRC C-701 and the TL-10A. Combat history Some news reports indicate that this was the missile used on July 14, 2006 in the 2006 Lebanon War when Hezbollah fired two at Israeli warships. One of the missiles hit the corvette INS ''Hanit'', causing heavy damage and the deaths of four Israeli servicemen. The other missile hit an Egyptian merchant ship causing heavy damage; it is reported that all the crew survived.

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 (ship), 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 ... [...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 ...

Jane's Fighting Ships
''Jane's Fighting Ships'' by Janes Information Services is an annual reference book of information on all the world's warships arranged by nation, including information on ships' names, dimensions, armaments, silhouettes and photographs, etc. Each edition describes and illustrates warships of different national naval and paramilitary forces, providing data on their characteristics. The first issue was illustrated with Jane's own ink sketches--photos began to appear with the third volume in 1900. The present title was adopted in 1905. It was originally published by Fred T. Jane in London in 1898 as ''Jane's All the World's Fighting Ships'', in order to assist naval officers and the general public in playing naval wargames. Its success eventually launched a number of military publications carrying the name "Jane's". It is a unit of Jane's Information Group, which is now owned by IHS. Ten early editions of Jane's (those of 1898, 1905-06, 1906-07, 1914, 1919, 1924, 1931, 1939, 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
