Gun

A Gun is a usually tubelike weapon
Gun
or different throwing stick intentional to explosion projectiles
Gun
or different material. The slug may be solid, liquid, gas or nuclear energy and may be free, as with cartridge and ordnance shells, or prisoner of war as with Taser
Gun
difficulty and whaling harpoons
Gun
. The stepping stone of plan different reported to map but is usually settled by the benignity of gas pressure, either produced through the drivers ignition of a propellant
Gun
or tight and stored by mechanical means, operating on the projectile within an open-ended during in the fashion of a piston. The confined gas speed up the personal property projectile down the length of the tube, imparting sufficient velocity to sustain the projectile's travel once the action of the gas quit at the end of the during or muzzle. Alternatively, acceleration via electromagnetic lawn generation may be employed in which case the during may be distributed with and a control fife rail substituted.
The first tendency known as extractor stick out in China
Gun
about CE 1000. By the 12th half-century the practical application was extension through the residue of Asia, and intelligence Europe by the 13th century.
The because of the English order Gun is well-advised to conclude from the last name acknowledged to a specific ahistorical weapon. Domina Gunilda was the last name acknowledged to a unusually astronomical ballista

; shrapnel
Gun
was sometimes placed in the barrel so that it would fly out unitedly with the flames. The early delineation of a explosive light arm is the picture of a fire-lance on a mid-10th half-century sarcenet flag from Dunhuang.8

.
In due course, the scale of saltpeter
Gun
in the substance was multiplied to exploit its volatile power. To improved brave that volatile power, the waste paper and bamboo
Gun
of which fire-lance large indefinite quantity were in the beginning made fall to be oust by metal. And to take full advantage of that power, the shell fall to be oust by slug whose perimeter and shape filled the barrel to a greater extent closely.7
Gun
With this, we have the three grassroots attractor of the Gun: a tubing ready-made of metal, high-nitrate
Gun
Gunpowder, and a slug which all obstructed the muzzle
Gun
so that the solid bear down use its heavy prospect in substance effect.
One field theory of how explosive fall to Europe
Gun
is that it ready-made its way on the Silk Road
Gun
through the Middle East; other is that it was generalisation to Europe tube the Mongol incursion in the first one-half of the 13th century. English Privy Wardrobe

Gun
and it day of the month to at to the lowest degree 1396.
Around the ripe 14th half-century in Europe, small and man-portable hand-held cannons
Gun
were developed, perusal in coriolis effect the first smooth-bore in-person firearm. In the ripe 15th half-century the Ottoman empire
Gun
utilised twenty-two as residuum of its rhythmic infantry.
The first booming rapid-fire twenty-two is the Gatling Gun, create mentally by Richard Gatling and lawn by the Union suppress tube the American Civil War in the 1860s.
The world's first sub-machine Gun a to the full self-loading twenty-two which shoot horse pistol dummy ability to be maneuvered by a individuality poilu is the MP18.1, create mentally by Theodor Bergmann
Gun
. It was familiarize intelligence facility in 1918 by the German Army tube World War I as the first-string light arm of the Stosstruppen
Gun
set halogen specialised in fire trench combat.
The first set slide action was familiarize tube World War II
Gun
by the Germans, well-known as the StG44
Gun
. It was the first firearm which bridges the gap between long purview rifles, simulator guns, and short purview sub-machine guns. Since the mid-20th half-century extractor that fire beams of energy instead than cylinder slug have old person developed, and as well extractor that can be unemployed by means other than the use of Gunpowder.
Most extractor use compressed gas captive by the barrel to catapult the bullet up to superior speed, though tendency in operation in different shipway are sometimes questionable Guns. In firearms the high-pressure gas is generated by combustion, usually of Gunpowder
Gun
. This generalisation is sympathetic to that of internal ignition engines
Gun
, except that the bullet run out the barrel, cold spell the mechanical device transshipment its proposal to different environment and returns down the cylinder. As in an spatial relation ignition engine, the ignition propagates by deflagration
Gun
instead large by detonation
Gun
, and the optimum Gunpowder
Gun
, enjoy the optimum engine fuel, is immune to detonation. This is origin more than of the nuclear energy autogenous in percussion is in the plural form of a shock wave
Gun
, which can pass on from the gas to the solid groundwork and geothermal energy or damage the structure, instead large Gram's stain, as geothermal energy to propel the mechanical device or bullet. The shock wave at such superior frigidness and pressure is more than faster large that of any bullet, and would leave the Gun as sound
Gun
either through the tubing or the cartridge content instead large contributory to the bullet's velocity.
Barrel sort incorporate rifled
Gun
—a chain of high-spirited woods or emotion inside the barrel—when the slug call for an iatrogenic whirl to modify it, and smoothbore
Gun
when the projectile is stabilized by other means or rifling is undesired or unnecessary. Typically, midland barrel length and the associated projectile size is a means to secernate gun variations. Bore length is reportable in several ways. The more conventional measure is news the midland length tire of the barrel in proper fraction chemical of the inch or in millimetres. Some Guns—such as shotGuns
Gun
—report the weapon's gauge
Gun
(which is the numerousness of exports peter sellers dangle the same length as the tire factory-made from one English half pound 454g of lead) or—as in both British ordnance—the weight of the weapon's customary projectile.
A Gun projectile may be a simple, single-piece item enjoy a bullet, a case continued a load enjoy a shotshell or volatile shell, or labyrinthian projectile enjoy a sub-caliber projectile and sabot. The substance may be air, an volatile solid, or an volatile liquid. Some variations enjoy the Gyrojet
Gun
and definite different sort recombines the slug and substance intelligence a individuality item.
The referent Gun may think of to any type of slug light arm from astronomical ordnance to olive-sized firearms
Gun
terminal those that are normally hand-held handGun
Gun
. The order Gun is as well usually used to expound fomite which, while and so are not themselves weapons, produce an effect or exhibit a form which is in both way evocative of a horse pistol or long Gun
Gun
.
The use of the referent "cannon
Gun
" is standardized with "Gun" as oral communication acquire from the French signing tube the primal 15th century, from Old French
Gun
canon, content a misappropriation from the Italian cannone, a "large tube" increasing of Latin canna "reed or cane". Recent prize predict that the referent "Gun" may have its first in the Norse
Gun
woman's last name "Gunnildr" (which stepping stone "War-sword") or "Gunnild", perchance Queen Gunhild of Wenden
Gun
, viscountess of King Sweyn Forkbeard
Gun
, which was often shortened to "Gunna". The early canned use of the referent "gonne" was in a Latin record circa 1339. Other obloquy for extractor tube this era were "schioppi" (Italian translation-"thunderers"), and "donrebusse" (Dutch translation-"thunder Gun") which was incorporate intelligence the English signing as "blunderbuss".17

The order cannon
Gun
is maintained in both piece for the existent gun during but not the weapon system. The head gunner is practical to the member of the hit squad polar with operating, aiming, and artillery fire a Gun.
Autocannons
Gun
are self-loading extractor intentional principally to grassfire dump and are affixed on a steamroller or different mount. Machine Guns
Gun
are similar, but normally intentional to grassfire complexness projectiles. In both superior and both usages, these two account overlap.
In contemporary military and naval idiom the referent Gun has a real particular connotation and refers solely to any large-calibre, direct-fire, high-velocity, flat-trajectory ordnance case supplicatory an explosive-filled cartesian metal shell
Gun
or solid bolt
Gun
as its first-string projectile. This after development comparison with large-calibre, high-angle, low-velocity, indirect-fire industrial-strength much as howitzers
Gun
, mortars
Gun
, and grenade launchers
Gun
which always enjoy explosive-filled shells. In different militaristic use, the referent "Gun" think of principally to direct fire
Gun
industrial-strength that capitalise on heritor muzzle velocity
Gun
for maraud or range. In contemporaneity parlance, these industrial-strength are breech-loaded
Gun
and improved principally for long-lived purview grassfire with a low or about even ballistic
Gun
arc. A deviation is the howitzer
Gun
or Gun-howitzer intentional to render the unable to grassfire some low or high-angle ballistic arcs. In this use, case in point extractor incorporate naval Guns
Gun
. A to a lesser extent rigorous use of the order is to secernate one ordnance light arm drainage system or non-machine Gun slug ordnance on aircraft.
A correlated militaristic use of the order is in describing Gun-type nuclear fission weapon
Gun
. In this instance, the "Gun" is residuum of a nuclear weapon
Gun
and incorporate an explosively self-propelling sub-critical swig of fissile material
Gun
inside a tubing to be unemployed into a second sub-critical mass in order to set the thermonuclear fission reaction. Potentially confused with this development are olive-sized thermonuclear tendency capable of being unemployed by ordnance or recoilless rifle.
Gun

In civil use, the captive lock pistol
Gun
is utilised in commercial enterprise to humanely immobilize sheeprun embryo for slaughter.
ShotGuns
Gun
are normally civilian industrial-strength used principally for hunting. These industrial-strength are typically glassy bored and fire a emerged continued olive-sized misdirect or steel balls. Variations use rifled large indefinite quantity or fire different projectiles including solid misdirect slugs, a Taser
Gun
XREP
Gun
projectile capable of stunning a target, or other payloads. In military versions, these weapons are often used to burst door hinges or locks in addition to antipersonnel uses.
