Railway Gun
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 railroad car, railway wagon. Many countries have built railway guns, but the best-known are the large Krupp-built pieces used by German Reich, Germany in World War I and World War II. Smaller guns were often part of an armoured train. They were 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railgun
A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a ranged weapon, that uses Electromagnet, electromagnetic force to launch high-velocity Projectile, projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage. The railgun uses a pair of parallel rail-shaped Electrical conductor, conductors (simply called rails), along which a sliding projectile called an 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, dart ammunition) rather than using conventional propellants. While explosive-powered milita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunnion
A trunnion () is a cylinder, cylindrical Boss (engineering), protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. In mechanical engineering (see the Trunnion#Trunnion bearings, trunnion bearing section below), it is one part of a rotating joint where a shaft (the trunnion) is inserted into (and turns inside) a full or partial cylinder. Medieval history In a cannon, the trunnions are two projections cast just forward of the center of mass of the cannon and fixed to a two-wheeled movable gun carriage. With the creation of larger and more powerful siege guns in the early 15th century, a new way of mounting them became necessary. Stouter gun carriages were created with reinforced wheels, axles, and “trails” which extended behind the gun. Guns were now as long as in length and they were capable of shooting iron projectiles weighing from . When discharged, these wrought iron balls were comparable in range ...

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 (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 Compagnie du chemin de fer de Paris à Orléans, Chemin de fer de Paris à Or ...

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 Compagnie, also known as Schneider-Creusot for its birthplace in the French town of Le Creusot, was a historic 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 at 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 a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character fo ...

BL 12 Inch Railway Gun
The British Ordnance BL 12 inch gun Mk IX on truck, railway mounted surplus 12 inch Mk IX W naval guns, manufactured by Woolwich Arsenal in 1906, on various railway platforms to provide mobile long-range heavy artillery for the British Army on the Western Front in World War I. History Vickers mounted two Mk IX W guns on slightly different railway mountings, Mk I, from September 1915. They are both identified by the open-frame appearance, recoil buffers above the barrel and the bogies with frames between the wheels similar to locomotive bogies. One mounting has a distinctive diamond-shape from the side and has a warping winch on the front; the other's carriage has a more squared-off profile with no warping winch at the front. The weapons on the Mk I mountings were originally reserve guns for HMS ''Cornwallis''. Elswick Ordnance Company (Armstrongs) mounted two more on its own design of Mk II railway mounting, delivered to the Western Front in August 1916. They are id ...
