Breechloader
A breechloader is a firearm in which the user loads the ammunition ( cartridge or shell) via the rear (breech) end of its barrel, as opposed to a muzzleloader, which loads ammunition via the front ( muzzle). Modern firearms are generally breech-loading – except for replicas of vintage weapons. Early firearms before the mid-19th century were almost entirely muzzle-loading. Mortars and the Russian GP-25 grenade launcher are the only muzzleloaders remaining in frequent modern usage. However, referring to a weapon specifically as breech loading is mostly limited to single-shot or otherwise non-repeating firearms, such as double-barreled shotguns. Breech-loading provides the advantage of reduced reloading time, because it is far quicker to load the projectile and propellant into the chamber of a gun/cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly an ...

Single-shot
Single-shot firearms are firearms that hold only a single round of ammunition, and must be reloaded manually after every shot. The history of firearms began with single-shot designs, then multi-barreled designs appeared, and eventually many centuries passed before multi-shot repeater designs became commonplace. Compared to repeating firearms, single-shot designs have no moving parts (other than the trigger and hammer/ firing pin or frizzen) and thus do not need a sizable receiver behind the barrel, and are much less complex than revolvers or magazine/belt-fed firearms. Although largely disappeared from military usage due to the slow rates of fire, single-shot designs are still produced by many manufacturers in both cartridge- and non-cartridge varieties, from zip guns to the highest-quality hunting and match guns. History Pre-cartridge era The vast majority of firearms before the introduction of metallic cartridges from the 1860s onwards, were single-shot muzzleloaders. ...

Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end ( muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons, so the pipe (often built from staves of metal) needed to be braced periodically along its length for structural reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name.''A History of Warfare'' - Keegan, John, Vintage 1993.

Breech-loading Swivel Gun
A breech-loading swivel gun was a particular type of swivel gun and a small breech-loading cannon invented in the 14th century. It was equipped with a swivel for easy rotation and was loaded by inserting a mug-shaped device called a chamber or breech block, filled with gunpowder and projectiles. It had a high rate of fire, as several chambers could be prepared in advance and quickly fired in succession and was especially effective in anti-personnel roles. It was used for centuries by many countries of Europe, Asia and Africa. Characteristics Although breech-loading is often considered a modern innovation which facilitated the loading of cannons,Turnbull, p. 105 breech-loading swivel guns were invented in the 14th century, and used worldwide from the 16th century onward by numerous countries, many of them non-European. They have been called by many names, sometimes "Murderer", "Base", "Sling", "Port-Piece", "Serpentine", "Culverin", "Pierrier", "Stock Fowler", and "Patterero" i ...

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamber (firearms)
In firearms, the chamber is the cavity at the back end of a breechloader's barrel or cylinder, where the cartridge is inserted before being fired. The rear opening of the chamber is the breech, and is sealed by the breechblock or the bolt. Function Rifles and pistols generally have a single chamber integral to their barrels, but revolvers have multiple chambers in their cylinder, and no chamber in their barrel. Thus, rifles and pistols can usually still be fired with the magazine removed as long as a cartridge is inserted into the chamber, while a revolver cannot be fired at all with its cylinder swung out. The act of ''chambering'' a cartridge means the insertion of a round into the chamber, either manually or through the action of the weapon, e.g., pump-action, lever-action, bolt action, or Autoloading operation generally in anticipation of firing the weapon, without need to "load" the weapon upon decision to use it (reducing the number of ''actions'' needed to di ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duchy Of Burgundy
The Duchy of Burgundy (; la, Ducatus Burgundiae; french: Duché de Bourgogne, ) emerged in the 9th century as one of the successors of the ancient Kingdom of the Burgundians, which after its conquest in 532 had formed a constituent part of the Frankish Empire. Upon the 9th-century partitions, the French remnants of the Burgundian kingdom were reduced to a ducal rank by King Robert II of France in 1004. Robert II's son and heir, King Henry I of France, inherited the duchy but ceded it to his younger brother Robert in 1032. Other portions had passed to the Imperial Kingdom of Burgundy-Arles, including the County of Burgundy (Franche-Comté). Robert became the ancestor of the ducal House of Burgundy, a cadet branch of the royal Capet dynasty, ruling over a territory that roughly conformed to the borders and territories of the modern region of Burgundy (Bourgogne). Upon the extinction of the Burgundian male line with the death of Duke Philip I in 1361, the duchy reverted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precision Engineering
Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time. These approaches have applications in machine tools, MEMS, NEMS, optoelectronics design, and many other fields. Overview Professors Hiromu Nakazawa and Pat McKeown provide the following list of goals for precision engineering: # Create a highly precise movement. # Reduce the dispersion of the product's or part's function. # Eliminate fitting and promote assembly, especially automatic assembly. # Reduce the initial cost. # Reduce the running cost. # Extend the life span. # Enable the design safety factor to be lowered. # Improve interchangeability of components so that corresponding parts made by other factories or firms can be used in their place. # Improve quality c ...
