Railway Artillery
A railway gun, also called a railroad gun, is a large artillery piece, often surplus naval artillery, mounted on, transported by, and fired from a specially designed railway wagon. Many countries have built railway guns, but the best-known are the large Krupp-built pieces used by Germany in World War I and World War II. Smaller guns were often part of an armoured train. Only able to be moved where there were good tracks, which could be destroyed by artillery bombardment or airstrike, railway guns were phased out after World War II. Design considerations The design of a railway gun has three firing issues over and above those of an ordinary artillery piece to consider. Namely how the gun is going to be traversed – i.e. moved from side to side to aim; how the horizontal component of the recoil force will be absorbed by the gun's carriage and how the vertical recoil force will be absorbed by the ground. Methods of traverse The first method of traverse is to rely entirel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railgun
A railgun or rail gun is a linear motor device, typically designed as a weapon, that uses Electromagnet, electromagnetic force to launch high velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high speed, mass, and kinetic energy to inflict damage. The railgun uses a pair of parallel conductors (rails), along which a sliding Armature (electrical engineering), armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. It is based on principles similar to those of the homopolar motor. As of 2020, railguns have been researched as weapons utilizing electromagnetic forces to impart a very high kinetic energy to a projectile (e.g. APFSDS) rather than using conventional propellants. While explosive-powered military guns cannot readily achieve a muzzle velocity of more than ≈, railguns can readily exceed . For a similar projectile, the ra ...

Brooke Rifle
The Brooke rifle was a type of rifled, muzzle-loading naval and coast defense gun designed by John Mercer Brooke, an officer in the Confederate States Navy. They were produced by plants in Richmond, Virginia, and Selma, Alabama, between 1861 and 1865 during the American Civil War. They served afloat on Confederate ships and ashore in coast defense batteries operated by the Confederate States Army. Design and production Brookes can be identified by the presence of at least one band of wrought iron at the breech and a rough-finished, tapering barrel. The barrels were made of cast iron for ease of manufacture, but one or more wrought iron bands was welded around the chamber to reinforce it against the high chamber pressure exerted when the gun fired. Because no southern foundries had the capacity to wrap the rifles in a single band like the Parrott design, a series of smaller bands were used, each usually thick and wide. All of Brooke's rifles used the same seven-groove rifling wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US Civil War Railway Gun And Crew
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americans ...

Voenizdat
Voenizdat (russian: Воениздат) was a publishing house in Moscow, Russia that was one of the first and largest publishing houses in USSR. The name is a Russian abbreviation for "Voennoe Izdatelstvo", meaning "Military Publication". Voenizdat was established by Revvoyensoviet on 25 October 1919. The initial aim was to publish literature for the needs of Ministry of Defence. It later published both fiction and non-fiction literature, technical manuals and dictionaries A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologies, p ....

Société De Construction Des Batignolles
The Société de Construction des Batignolles was a civil engineering company of France created in 1871 as a public limited company from the 1846 limited partnership of ''Ernest Gouin et Cie.''. Initially founded to construct locomotives, the company produced the first iron bridge in France, and moved away from mechanical to civil engineering projects in France, North Africa, Europe, and in East Asia and South America. In 1968 the company merged with the electrical engineering company SPIE to form Spie Batignolles. After being briefly owned by the AMEC group (2003) the civil engineering construction activities were split and sold. As of 2011, Spie Batignolles SA is the effective successor of the company. History Ernest Goüin et Cie. On 18 February 1847, Ernest Goüin, having gained experience in England on the manufacture of locomotives and machine tools whilst acting on behalf of the Chemin de fer de Paris à Orléans, founded the company ''Ernest Gouin et Cie.''

BL 12 Inch Railway Howitzer
The British Ordnance BL 12 inch howitzer on truck, railway, a type of railway gun, was developed following the success of the 9.2-inch siege howitzer. It was similar but unrelated to the 12-inch siege howitzers Mk II and IV. Design and development Mark I Mk I was introduced from March 1916. It is identified by its short barrel and recuperator above the barrel. Mark III The longer-barrelled Mk III soon followed, with a heavier breech to balance the gun. It retained the recuperator above the barrel. Mark V Mk V, dating from July 1917, moved the recoil buffer and recuperator into a single housing below the barrel, which was common for all new British artillery developed during World War I. It also had a lighter breech with the gun balanced by the redesigned recoil system and altered gun positioning on the cradle.Hogg & Thurston 1972, page 186 Mk V also relocated the loading platform from the railway wagon to the revolving gun mounting, which now allowed 120° of traverse, ...

Schneider-Creusot
Schneider et Cie, also known as Schneider-Creusot for its birthplace in the French town of Le Creusot, was a historic French iron and steel-mill company which became a major arms manufacturer. In the 1960s, it was taken over by the Belgian Empain group and merged with it in 1969 to form Empain-Schneider, which in 1980 was renamed Schneider SA and in 1999, after much restructuring, Schneider Electric. Origins In 1836, Adolphe Schneider and his brother Eugène Schneider bought iron-ore mines and forges around Le Creusot (Saône-et-Loire). They developed a business dealing in steel, railways, armaments, and shipbuilding. The Creusot steam hammer was built in 1877. Somua, a subsidiary located near Paris, made machinery and vehicles, including the SOMUA S35 tank.

240 Mm St Chamond Railway Gun Diagram
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...
