Uzushio-class Submarine
The ''Uzushio''-class submarine was a series of seven submarines in service with Japanese Maritime Self Defense Force during the Cold War between 1972 and the mid-1990s. They were the first generation of the Teardrop hull, teardrop type submarine that valued the underwater performance against that of the preceding conventional-hull type . Many were converted to training submarines (ATSS) towards the end of their lives. General characteristics The ''Uzushio'' class was the first Japan Maritime Self-Defense Force submarine design to incorporate the teardrop hull. The ''Uzushio''s had a double hull construction which used NS-63 high-tensile steel to allow for a deeper diving depth of . The submarines measured Length between perpendiculars, long between perpendiculars and at the Beam (nautical), beam. They had a maximum Draft (hull), draught of and had a standard displacement of and a displacement when submerged. The submarines were powered by a diesel-electric system composed o ...

Kawasaki Shipbuilding Corporation
is the shipbuilding subsidiary of Kawasaki Heavy Industries. It produces primarily specialized commercial vessels, including LNG carriers, LPG carriers, container ships, bulk carriers, oil tankers, as well as high speed passenger jetfoils. In addition, it is also a producer of warships for the Japan Maritime Self-Defense Force, including submarines. Kawasaki also produces marine machinery, including marine engines, thrusters, steering gears, deck and fishing machinery. History Kawasaki's origins go back to April 1878, when Shozo Kawasaki established Kawasaki Tsukiji Shipyard in Tokyo with the support of fellow Satsuma domain, Satsuma native and Ministry of Finance (Japan), Vice Minister of Finance, Matsukata Masayoshi. In 1886, Kawasaki established a second shipyard in Kobe, Hyōgo prefecture. With the First Sino-Japanese War, the two shipyards were flooded with new orders and ship repair requests. The two shipyards were merged in 1896 as the Kawasaki Dockyard Company, Ltd. Rea ... [...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 sides 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 cora ...

Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, 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 somet ...

3D Projection
A 3D projection (or graphical projection) is a Design, design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on perspective (graphical), visual perspective and aspect analysis to Projection mapping, project a complex object for viewing capability on a simpler plane. 3D projections use the Primary Qualities, primary qualities of an object's basic shape to create a map of points, that are then connected to one another to create a visual element. The result is a graphic that contains conceptual properties to interpret the figure or image as not actually flat (2D), but rather, as a solid object (3D) being viewed on a 2D display. 3D objects are largely displayed on two-dimensional mediums (such as paper and computer monitors). As such, graphical projections are a commonly used design element; notably, in engineering drawing, technical drawing, drafting, and computer graphics. Projections can be calculated through ...
