Bliss-Leavitt Mark 3 Torpedo
The Bliss-Leavitt Mark 3 torpedo was a Bliss-Leavitt torpedo adopted by the United States Navy in 1906 for use in an anti-surface ship role. Characteristics The Bliss-Leavitt Mark 3 was very similar to the Bliss-Leavitt Mark 2 torpedo. The primary difference was a longer range of 4000 yards. Approximately 200 Mark 3s were produced for the US Navy. The Bliss-Leavitt Mark 3 was launched from battleships, torpedo boats and cruisers. See also *American 21 inch torpedo There have been a number of 21-inch torpedoes in service with the United States. These have been used on ships and submarines of the U.S. Navy.

Anti-surface Warfare
Anti-surface warfare (ASuW or ASUW) is the branch of naval warfare concerned with the suppression of surface combatants. More generally, it is any weapons, sensors, or operations intended to attack or limit the effectiveness of an adversary's surface ships. Before the adoption of the submarine and naval aviation, all naval warfare consisted of anti-surface warfare. The distinct concept of an anti-surface warfare capability emerged after World War II, and literature on the subject as a distinct discipline is inherently dominated by the dynamics of the Cold War. Categories of anti-surface warfare Anti-surface warfare can be divided into four categories based on the platform from which weapons are launched: * Air (or aviation): Anti-surface warfare conducted by aircraft. Historically, this was conducted primarily through level- or dive-bombing, strafing runs or air-launching torpedoes (and in some cases by suicide attacks). Today, air ASuW is generally conducted by stand-off at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
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 ...

Frank McDowell Leavitt
Frank McDowell Leavitt (1856–1928) was an American engineer and inventor. Leavitt devised one of the earliest machines for manufacturing tin cans and later invented the Bliss-Leavitt torpedo, the chief torpedo used by United States Navy in World War I. Leavitt was part of an emerging cadre of American engineers whose design feats were putting United States manufacturing might on the map at the dawn of the twentieth century. Early life and career beginnings Frank M. Leavitt was born at Athens, Ohio, on March 3, 1856, the son of Rev. John McDowell Leavitt, later president of Lehigh University, and his wife Bethia (Brooks) Leavitt of Cincinnati, Ohio. Leavitt married Ohio-born Gertrude Goodsell at Brooklyn, New York, on November 8, 1893, and settled in Brooklyn Heights, New York, where he pursued his career as an engineer. Within a decade of his marriage, Leavitt had patented an early – and lucrative – process to manufacture tin cans. Bliss-Leavitt torpedo By 1 ...

Guncotton
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. Production The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses. In precise chemical terms, nitrocellulose is not a nitro compound, but a nitrate ester. The glucose repeat unit (anhydroglucose) within t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine Engine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller ( turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission ( turboshaft), marine propeller or electrical generator (power turbine). Grea ...

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. Gyrosco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bliss-Leavitt Torpedo
The Bliss-Leavitt torpedo was a torpedo designed by Frank McDowell Leavitt and manufactured by the E. W. Bliss Company of Brooklyn, New York. It was put into service by the United States Navy in 1904 and variants of the design would remain in its inventory until the end of World War II. History The E. W. Bliss Company secured manufacturing rights to the Whitehead torpedo in 1892 and thereafter supplied the US Navy with this weapon. In 1904, an engineer with E. W. Bliss, Frank M. Leavitt, designed a torpedo with a "single-stage vertical turbine engine" that utilized compressed air preheated by alcohol. This design became the Bliss-Leavitt Mark 1 torpedo, the first non-Whitehead design after the Howell torpedo. The Mark 1 had a tendency to roll, affecting its directional stability. This was remedied by Lieutenant Gregory C. Davison who proposed a two-stage turbine design that drove contra-rotating propellers. This cancelled the torque effect of the single-stage design, improvin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bliss-Leavitt Mark 2 Torpedo
The Bliss-Leavitt Mark 2 torpedo was a Bliss-Leavitt 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, which had been building Whitehead torpedoes for the US Navy, began designing and manufacturing their own torpedoes in 1904. It was the first American-built torpedo to feature counter-rotating turbines, each driving a propeller. This design eliminated the unbalanced torque that contributed to the tendency of its predecessor (the Bliss-Leavitt Mark 1 torpedo) to roll. Characteristics The design of the Bliss-Leavitt Mark 1 torpedo was revolutionary, but not without problems. The single-stage turbine engine drove a single propeller, which had a tendency to develop unbalanced torque and thus to roll in the water, affecting its accuracy. This problem was corrected by Navy Lieutenant Gregory Davison in the Mark 2 by using a twin-turbine engine driving twin propellers, thus steadying the torpedo's trajector ...
