22.5 Cm Minenwerfer M 15
The 22.5 cm Minenwerfer M 15 was a heavy mortar used by Austria-Hungary in World War I. It was developed by Böhler as an alternative to the German Ehrhardt 25 cm schwere Minenwerfer which Böhler was having problems building under license. It was a muzzle-loading, smooth-bore mortar that had no recoil system whatsoever. The entire mortar had to be levered around to aim at new targets. It was not particularly accurate and bombs often fell over in flight and landed on their sides so they used time instead of contact fuzes. It fired high-explosive and gas shells. For transport two wheels from the Gebirgsgechütz M 99 were used. The M 17 version of this weapon had an elevation screw with a double thread and reinforced trunnion A trunnion (from Old French "''trognon''", trunk) is a cylindrical protrusion used as a mounting or pivoting point.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

Mortar (weapon)
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that ... [...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, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheinmetall
Rheinmetall AG is a German automotive and arms manufacturer, headquartered in Düsseldorf, Germany Germany, officially the Federal Republic of Germany (FRG),, is a country in Central Europe. It is the most populous member state of the European Union. Germany lies between the Baltic and North Sea to the north and the Alps to the sou .... Its shares are traded on the Frankfurt stock exchange. History Rheinmetall was founded in 1889. Banker and investor Lorenz Zuckermandel (1847–1928) was one of the founders and the first chairman of the supervisory board. It manufactured steel products, including armaments. During the post-WWI disarmament of Germany, the company diversified, but by the 1930s armament manufacture resumed. In 1933, it acquired A. Borsig GmbH, which manufactured locomotives.

25 Cm Schwere Minenwerfer
The 25 cm schwerer Minenwerfer (heavy mine launcher), often abbreviated as 25 cm sMW, was a heavy mine shell launching trench mortar developed for the Imperial German Army in the first decade of the 20th century. Design and development It was developed for use by engineer troops after the Siege of Port Arthur during the Russo-Japanese War of 1904–05 illustrated the usefulness of this class of weapon in destroying bunkers and fortifications immune to normal artillery. The 25 cm schwerer Minenwerfer was a muzzle-loading, rifled mortar that had a hydro-spring type recoil system. It fired either a shell or a mine shell; both containing far more explosive filler than ordinary artillery ammunition of the same caliber. The low muzzle velocity allowed for thinner shell walls, hence more space for filler for the same weight shell. The low velocity also allowed the use of explosives like ammonium nitrate–carbon that were less shock-resistant than TNT, which was in shor ...

Contact Fuze
A contact fuze, impact fuze, percussion fuze or direct-action (D.A.) fuze (''UK'') is the fuze that is placed in the nose of a bomb or shell so that it will detonate on contact with a hard surface. Many impacts are unpredictable: they may involve a soft surface, or an off-axis grazing impact. The pure contact fuze is often unreliable in such cases and so a more sensitive graze fuze or inertia fuze is used instead. The two types are often combined in the same mechanism.Fuze, D.A. and Percussion, No. 119, Artillery fuzes The British Army's first useful impact fuze for high-explosive shells was the '' Fuze No. 106'' of World War I. (''illus.'') This used a simple protruding plunger or ''striker'' at the nose, which was pushed back to drive a firing pin into the detonator. Its ability to burst immediately at ground level was used to clear the barbed wire entanglements of no man's land, rather than burying itself first and leaving a deep, but useless, crater.

High-explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunnion
A trunnion (from Old French "''trognon''", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion. In mechanical engineering (see the 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. As they allowed the muzzle to be raised and lowered easily, the integral casting of trunnions is seen by military historians as one of the most important advances in early field artillery. With the creation of larger and more powerful siege guns in the early 15th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
