Whitehead Mark 2 Torpedo
The Whitehead Mark 2 torpedo was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. It was identical to the Whitehead Mark 1 torpedo, except for some mechanical details. Characteristics The Mark 2 was ordinarily assembled into three sections: the warhead, the air flask and the after-body. The warhead's charge of wet guncotton weighed 118 pounds. The Mark 2 was what was known as a "cold-running" torpedo. The three-cylinder reciprocating engine ran on cold, compressed air which was stored in the air flask, which had a capacity of 7.154 cubic feet at 1350 pounds per square inch. The after-body carried the engine and the tail, which contained the propellers. The Mark 2 guidance component included the Pendulum-and-hydrostat control device which was called the "Whitehead Secret". This version of the Whitehead torpedo lacked the gyroscope gear designed by Lu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austria-Hungary
Austria-Hungary, often referred to as the Austro-Hungarian Empire,, the Dual Monarchy, or Austria, was a constitutional monarchy and great power in Central Europe between 1867 and 1918. It was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after its defeat in the First World War. Austria-Hungary was ruled by the House of Habsburg and constituted the last phase in the constitutional evolution of the Habsburg monarchy. It was a multinational state and one of Europe's major powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedoes Of The United States
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 ...

American 18 Inch Torpedo
There have been a number of 18-inch torpedoes in service with the United States. These have been used on ships and submarines of the US Navy. American "18-inch" torpedoes were actually in diameter, beginning with the "Fiume" Whitehead torpedo of 1890. Ship classes that carried 18-inch torpedoes include: * ''Aylwin''-class destroyers * B-class through some R-class submarines * ''Bainbridge''-class destroyers * ''Cassin''-class destroyers * ''Cincinnati''-class cruisers * ''Columbia''-class cruisers * ''Illinois''-class battleships * ''Indiana''-class battleships * ''Kearsarge''-class battleships * ''Maine''-class battleships * ''Montgomery''-class cruisers * ''Paulding''-class destroyers * ''Pennsylvania''-class cruisers * ''Plunger''-class submarines * ''Smith''-class destroyers * ''Truxtun''-class destroyers See also *American 21-inch torpedo There have been a number of 21-inch torpedoes in service with the United States.

USS Holland (SS-1)
USS ''Holland'' (SS-1) was the United States Navy's first modern commissioned submarine, although not the first military submarine of the United States, which was the 1775 submersible ''Turtle''. The boat was originally laid down as ''Holland VI'' at the Crescent Shipyard of Elizabeth, New Jersey for John Philip Holland's Holland Torpedo Boat Company, and launched on 17 May 1897. She was acquired by the USN on 11 April 1900 and commissioned on 12 October 1900, Lieutenant H. H. Caldwell commanding.Friedman, p. 286 Design and construction ''Holland'' was built at former Navy Lieutenant Lewis Nixon's Crescent Shipyard of Elizabeth, New Jersey for John Holland's Holland Torpedo Boat Company, which became the Electric Boat company in 1899. The vessel was built under the supervision of John Philip Holland, who designed the vessel and her details. ''Holland''s keel was laid at Nixon's Crescent Shipyard with both men present. The two men worked together using many of John Holland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitehead Mark 3 Torpedo
The Whitehead Mark 3 torpedo was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. The primary difference between the Mark 3 and the previous versions of the 3.55-meter Whiteheads was the inclusion of the Obry steering gyro for azimuth control. This device reduced the maximum deviation right or left of the target from 24 to 8 yards. About 100 Mark 3s were purchased from the E. W. Bliss Company; in 1913, these were redesignated Torpedo Type A. They were used on submarines of the A, B, C and D classes. These were withdrawn from service use in 1922 when all torpedoes designed before the Bliss-Leavitt Mark 7 torpedo were condemned. Characteristics The Mark 3 was ordinarily assembled into three sections: the warhead, the air flask and the after-body. The warhead's charge of wet guncotton weighed 118 pounds. The Mark 3 was what was known as a "cold-runni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Obry
Ludwig Obry was an Austrian engineer and naval officer of the Austrian Navy who invented a gyroscopic device for steering a torpedo in 1895. The gyroscope was invented by Leon Foucault in 1851 but industry ignored the device for nearly 50 years. In 1895 or 1896, Obry rediscovered Foucault's device and adapted it into a mechanism for steering a torpedo. This increased the weapon's accuracy from hundreds to thousands of yards. Obry then patented his device and sold the rights to Robert Whitehead, who incorporated the mechanism into the Whitehead torpedo. The device consisted of a bronze wheel weighing less than 1.5 pounds that was spun by an air jet. Obry's device was notable for solving many problems; how to get the gyroscope to begin rotating as quickly as possible, how to direct the vertical rudder A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air o ...

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submerged submarine. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes ca ...

Bureau Of Ordnance
The Bureau of Ordnance (BuOrd) was a United States Navy organization, which was responsible for the procurement, storage, and deployment of all naval weapons, between the years 1862 and 1959. History Congress established the Bureau in the Department of the Navy by an act of July 5, 1862 (12 Stat. 510), which transferred the hydrographic functions of the Navy's Bureau of Ordnance and Hydrography (1842–1862) to the newly established Bureau of Navigation. During the early 20th century, BuOrd became involved in the development of aerial weapons. This often led to friction with the Bureau of Aeronautics (BuAer), which had responsibility for the development of Naval aircraft. BuAer's work on "pilotless aircraft," or drones, conflicted with BuOrd's development of guided missiles. After World War II, the Navy examined ways to improve coordination between the two bureaus; ultimately, the decision was made to merge the two organizations into a new bureau, to be known as the Bureau of ...

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] |
