Cannonball
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball. The cast iron cannonball was introduced by a French artillery engineer Samuel J. Besh after 1450; it had the capacity to reduce traditional English castle wall fortifications to rubble. French armories would cast a tubular cannon body in a single piece, and cannonballs took the shape of a sphere initially made from stone material. Advances in gunpowder manufacturing soon led the replacement of stone cannonballs with cast iron ones. Round shot was made in early times from dressed stone, referred to as gunstone (Middle English: ''gunneston''), but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smoothbore cannon, used to batter the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Cannon Projectiles
A cannon is any large tubular firearm designed to fire a heavy projectile over a long distance. They were first used in Europe and China, and were the archetypical form of artillery. Round shot and grapeshot were the early projectiles used in cannon. Projectiles fired from cannon ; Round shot or solid shot or a cannonball or simply ball: A solid spherical projectile made, in early times, from dressed stone but, by the 17th century, from iron. The most accurate projectile that could be fired by a smooth-bore cannon, used to batter the wooden hulls of opposing ships, forts, or fixed emplacements, and as a long-range anti-personnel weapon. ; Chain shot or Split shot : Two sub-calibre round shot (a good deal smaller than the bore of the barrel) linked by a length of chain or a solid bar, and used to slash through the rigging and sails of an enemy ship so that it could no longer manoeuver. It was inaccurate and only used at close range. Two-headed bullets (angels) were simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star Fort
A bastion fort or ''trace italienne'' (a phrase derived from non-standard French, literally meaning ''Italian outline'') is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield. It was first seen in the mid-fifteenth century in Italy. Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era. The design of the fort is normally a polygon with bastions at the corners of the walls. These outcroppings eliminated protected blind spots, called "dead zones", and allowed fire along the curtain from positions protected from direct fire. Many bastion forts also feature cavaliers, which are raised secondary structures based entirely inside the primary structure. Origins Their predecessors, medieval fortresses, were usually placed on high hills. From there, arrows were shot at the enemies. The enemies' hope was to either ram the gate or c ...

Cannon
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons.

Negro Fort
Negro Fort (African Fort) was a short-lived fortification built by the British in 1814, during the War of 1812, in a remote part of what was at the time Spanish Florida. It was intended to support a never-realized British attack on the U.S. via its southwest border, by means of which they could "free all these Southern Countries tatesfrom the Yoke of the Americans." Built on a site overlooking the Apalachicola River, about 15 miles north of present-day Appalachicola, Florida, it was the largest structure between St. Augustine and Pensacola. Trading posts of Panton, Leslie and Company and then John Forbes and Company, loyalists hostile to the United States, had existed since the late eighteenth century there and at the San Marcos fort, serving local Native Americans and fugitive slaves. The latter, runaway or freed colored slaves from plantations in the American South, used their experience of farming and animal husbandry to set up farms stretching for miles along the river. ...

Smoothbore
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, ...

Shell (projectile)
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles that is properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape ...

Gyroscopic
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. Gyroscopes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ogival
An ogive ( ) is the roundly tapered end of a two-dimensional or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture and woodworking. Etymology The earliest use of the word ''ogive'' is found in the 13th century sketchbook of Villard de Honnecourt, from Picardy in northern France. The ''Oxford English Dictionary'' considers the French term's origin obscure; it might come from the Late Latin , the feminine perfect passive participle of , meaning the one who has met or encountered the other. However, Merriam-Webster's dictionary says it is from the "Middle English stone comprising an arch, from Middle French diagonal arch". Types and use in applied physical science and engineering In ballistics or aerodynamics, an ogive is a pointed, curved surface mainly used to form the approximately streamlined nose of a bullet or other projectile, reducing air resistance or the drag of air. In fact the French word ''ogive'' can be translated as "nose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carcass (projectile)
A carcass was an early form of incendiary bomb or shell, intended to set targets on fire. It comprised an external casing, usually of cast iron, filled with a highly flammable mixture, and having three to five holes through which the burning filling could blaze outward."Carcass". ''Oxford English Dictionary''. Oxford University Press. 2nd edition. 1989. Carcasses were shot from howitzers, mortars, and other cannons to set fire to buildings and defences; on impact, the shell shattered, spreading its incendiary filling around the target. Congreve rockets were also sometimes fitted with carcass heads. They were named ''carcass'' because the circles which pass from one ring, or plate, to the other, were thought to resemble the ribs of a human carcass. History Carcasses were used for the first time by the French and Münsterite troops under Louis XIV and Bernard von Galen in 1672. They were also fired from bomb vessels. The carcass shell as used by the Royal Navy in the 18th and earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Bosworth
The Battle of Bosworth or Bosworth Field was the last significant battle of the Wars of the Roses, the civil war between the houses of Lancaster and York that extended across England in the latter half of the 15th century. Fought on 22 August 1485, the battle was won by an alliance of Lancastrians and disaffected Yorkists. Their leader Henry Tudor, Earl of Richmond, became the first English monarch of the Tudor dynasty by his victory and subsequent marriage to a Yorkist princess. His opponent Richard III, the last king of the House of York, was killed during the battle, the last English monarch to die in combat. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it one of the defining moments of English history. Richard's reign began in 1483 when he seized the throne from his twelve-year-old nephew Edward V. The boy and his younger brother Richard soon disappeared, to the consternation of many, and Richard's support was further eroded ...
