Paris Gun
The Paris Gun (german: Paris-Geschütz / Pariser Kanone) was the name given to a type of German long-range siege gun, several of which were used to bombard Paris during World War I. They were in service from March to August 1918. When the guns were first employed, Parisians believed they had been bombed by a high-altitude Zeppelin, as the sound of neither an airplane nor a gun could be heard. They were the largest pieces of artillery used during the war by barrel length, and qualify under the (later) formal definition of large-calibre artillery. Also called the "''Kaiser Wilhelm Geschütz''" (" Kaiser Wilhelm Gun"), they were often confused with Big Bertha, the German howitzer used against Belgian forts in the Battle of Liège in 1914; indeed, the French called them by this name as well.For an instance of war-time naming of this gun as "Big Bertha", see They were also confused with the smaller "Langer Max" (Long Max) cannon, from which they were derived; although the famous Krup ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was 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, 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 within the Ottoman Empire and in the 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 France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Projectile
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). In ballistics mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact. Motive force Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder. Light-gas guns use a combination of these mechanisms. Railguns utilize electromagnetic fields to provide a constant acceleration along the entire length of the device, greatly increasing the muzzle velocity. Some projectiles provide propulsion during flight by means of a rocket engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miller Paris Gun Shell Diagrams
A miller is a person who operates a mill, a machine to grind a grain (for example corn or wheat) to make flour. Milling is among the oldest of human occupations. "Miller", "Milne" and other variants are common surnames, as are their equivalents in other languages around the world (" Melnyk" in Russian, Belorussian & Ukrainian, "Meunier" in French, " Müller" or "Mueller" in German, "Mulder" and "Molenaar" in Dutch, "Molnár" in Hungarian, "Molinero" in Spanish, "Molinaro" or "Molinari" in Italian etc.). Milling existed in hunter-gatherer communities, and later millers were important to the development of agriculture. The materials ground by millers are often foodstuffs and particularly grain. The physical grinding of the food allows for the easier digestion of its nutrients and saves wear on the teeth. Non-food substances needed in a fine, powdered form, such as building materials, may be processed by a miller. Quern-stone The most basic tool for a miller was the quern- ...

Project Babylon
Project Babylon was a space gun project commissioned by then Iraqi president Saddam Hussein. It involved building a series of " superguns". The design was based on research from the 1960s Project HARP led by the Canadian artillery expert Gerald Bull. There were most likely four different devices in the program. The project began in 1988; it was halted in 1990 after Bull was assassinated, and parts of the superguns were seized in transit around Europe. The components that remained in Iraq were destroyed by the United Nations after the 1991 Persian Gulf War. Devices Baby Babylon The first of these superguns, "Baby Babylon", was a horizontally mounted device which was a prototype for test purposes. It had a bore of 350 mm (13.8 inches), and a barrel length of 46 metres (151 feet), and weighed some 102 tonnes. After conducting tests with lead projectiles, this gun was set up on a hillside at a 45 degree angle. It was expected to achieve a range of 750 km. Alth ...

V-3 Cannon
The V-3 (german: Vergeltungswaffe 3, ("Vengeance Weapon 3") was a German World War II large-caliber gun working on the multi-charge principle whereby secondary propellant charges are fired to add velocity to a projectile. The Germans planned to use the weapon to bombard London from two large bunkers in the Pas-de-Calais region of northern France, but they were rendered unusable by Allied bombing raids before completion. Two similar guns were used to bombard Luxembourg from December 1944 to February 1945. The V-3 was also known as the ''Hochdruckpumpe'' ("High Pressure Pump," HDP for short), which was a code name intended to hide the real purpose of the project. It was also known as ''Fleißiges Lieschen'' ("Busy Lizzie"). (bottom of page) Description The gun used multiple propellant stages placed along the barrel's length in order to provide an additional boost. These were ignited by the hot gases that propelled the projectile as it passed them. Solid-fuel rocket boosters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaiserliche Marine
{{italic title The adjective ''kaiserlich'' means "imperial" and was used in the German-speaking countries to refer to those institutions and establishments over which the ''Kaiser'' ("emperor") had immediate personal power of control. The term was used particularly in connexion with the Roman-German Emperor as sovereign of the Holy Roman Empire and with the subsequent Empire of Austria. In the Early Modern Period the term is linked with the universal precedence of the ''Kaiser'' over the other princes of the realm. Holders of an imperial or ''kaiserliche'' office were recruited from the whole empire, and had wide-ranging privileges in the territories. Examples of military, political and cultural institutions with ''kaiserliche'' players in the Holy Roman Empire are the: * ''Kaiserliche Armee'' ( Imperial Army) and * ''Kaiserliche Reichspost'' (Imperial Post Office) of the Roman-German Emperor (to 1806) (Habsburg, only 1742–1745 Wittelsbach) * ''kaiserliches Hofgestüt'' (Im ...

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Yaw (rotation)
A yaw rotation is a movement around the yaw axis of a rigid body that changes the direction it is pointing, to the left or right of its direction of motion. The yaw rate or yaw velocity of a car, aircraft, projectile or other rigid body is the angular velocity of this rotation, or rate of change of the heading angle when the aircraft is horizontal. It is commonly measured in degrees per second or radians per second. Another important concept is the yaw moment, or yawing moment, which is the component of a torque about the yaw axis. Measurement Yaw velocity can be measured by measuring the ground velocity at two geometrically separated points on the body, or by a gyroscope, or it can be synthesized from accelerometers and the like. It is the primary measure of how drivers sense a car's turning visually. It is important in electronic stabilized vehicles. The yaw rate is directly related to the lateral acceleration of the vehicle turning at constant speed around a constant radi ...

38 Cm SK L/45 "Max"
The 38 cm SK L/45 "Max",In Imperial German Navy gun nomenclature, "SK" (german: Schnelladekanone) denotes that the gun is quick firing, while the L/45 denotes the length of the gun. In this case, the L/45 gun is 45 calibers, meaning that the gun is 45 times as long as it is in diameter. also called Langer Max (literal translation "Long Max") was a German long-range, heavy siege and coast-defense gun used during World War I. Originally a naval gun, it was also adapted for land service when it became clear that some of the ships for which it was intended would be delayed and that it would be very useful on the Western Front. The first guns saw service in fixed positions (for example at Verdun in February 1916), but the lengthy preparation time required for the concrete emplacements was a severe drawback and a railroad mount was designed to increase the gun's mobility. The latter variants participated in the 1918 German spring offensives and the Second Battle of the Marne. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
