Panzerwurfkörper 42
The Panzerwurfkörper 42 was a HEAT grenade that was developed by Germany and used by the Wehrmacht during World War II. The Panzerwurfkörper 42 was designed to be fired from a ''Leuchtpistole'' or flare gun in English. Design The Panzerwurfkörper 42 was an anti-tank grenade that could be fired from the Leuchtpistole 34, Leuchtpistole 42, or Sturmpistole giving German troops a small and lightweight anti-tank weapon for engaging enemy armor from close range which could not be engaged satisfactorily by infantry weapons or artillery without endangering friendly troops. The Panzerwurfkörper 42's layout was similar to the Wurfkorper 361 its primary components were a nose cap, internal steel cone, steel upper body, steel stem, rifled driving band, explosive filling, and a graze fuze. The Leuchtpistole was a break action gun and a rifled brass or aluminum shell casing A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, sho ...

HEAT
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sturmpistole
The ''Sturmpistole'' ("assault-pistol") was an attempt by Germany during World War II to create a multi-purpose weapon which could be used by any infantryman. It consisted of a modified flare gun (''Leuchtpistole'') which could fire a variety of grenades, including a shaped charge Panzerwurfkörper 42 which could penetrate of rolled homogeneous armor. The idea was not pursued wholeheartedly, and took second stage to the then current anti-tank rifles and later weapon developments, such as the ''Panzerfaust'' recoilless and ''Panzerschreck'' rocket. Service use The ''Sturmpistole'' was a multi-purpose weapon for signaling, illumination, target marking, or concealment with a smoke grenade. Later during World War II, explosive rounds were developed to give German troops a small and lightweight grenade launcher for engaging targets from close range which could not be engaged satisfactorily by infantry weapons or artillery without endangering friendly troops.

Rifle Grenades
A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand. The practice of projecting grenades with rifle-mounted launchers was first widely used during World War I and World War II and continues to the present, with the term "rifle grenade" now encompassing many different types of payloads including high explosive, fragmentation, anti-tank warheads, concussion, smoke, incendiary, and flare missiles. Rifle grenades have largely been supplanted in the infantry fire support role by a combination of grenade launchers (typically affixed to rifles) and disposable anti-armor rockets. History Early use Adaptation of grenades for use in rifles began around the 18th century, when cup-shaped dischargers were fitted to the barrels of flintlock muskets, with the grenades propelled by the force of a blank cartridge. During the early 20th century a Japanese Colonel Amazawa experimented ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grenade Launchers
A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, Smoke screen, smoke or tear gas, gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade Cartridge (firearms), cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces. Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 grenade launcher, Mk 19 are mounted on tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense. History Early precursors The earliest devices which could be referred to as grenade launchers were Sling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grenades Of Germany
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a Shell (projectile), shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal Firing pin, striker to trigger the detonator, and a safety lever secured by a split pin, cotter pin. The user removes the safety pin before throwing, and once the grenade leaves the hand the safety lever gets released, allowing the striker to trigger a Percussion cap, primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (High explosive, high-explosive, Anti-tank grenade, anti-tank and stun grenades), chemical aerosols (Smoke grenade, smoke and gas grenades) or fire (incendiary grenades).

Superplasticity
In materials science, superplasticity is a state in which solid Crystallinity, crystalline material is deformed well beyond its usual breaking point, usually over about 600% during tensile deformation. Such a state is usually achieved at high homologous temperature. Examples of superplastic materials are some fine-grained metals and ceramics. Other non-crystalline materials (amorphous) such as silica glass ("molten glass") and polymers also deform similarly, but are not called superplastic, because they are not crystalline; rather, their deformation is often described as Newtonian fluid. Superplastically deformed material gets thinner in a very uniform manner, rather than forming a "neck" (a local narrowing) that leads to fracture. Also, the formation of microvoids, which is another cause of early fracture, is inhibited. In metals and ceramics, requirements for it being superplastic include a fine grain size (less than approximately 20 micrometres) and a fine dispersion of therma ...

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

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 ...

Break Action
Break action is a type of firearm action in which the barrel or barrels are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barrelled shotguns, double-barrelled rifles, combination guns, and are also common in single shot pistols (especially derringers), rifles, shotguns, and can also be found in flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions. Description Break action The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. A substantial hinge pin joins the two parts of the rifle or shotgun; the stock with its firing mechanism and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leuchtpistole 42
The Leuchtpistole 42 or flare gun in English was introduced into German service in 1943 and served throughout World War II. Design The Leuchtpistole 42 was a single shot, break action, smoothbore, flare gun that was a successor to the earlier Leuchtpistole 34. The Leuchtpistole 42 which was made from stamped mild steel components, was galvanized to stop corrosion and used bakelite for the pistol grips. The focus of the Leuchtpistole 42 was to reduce the consumption of light alloys, reduce reliance on machined components, reduce production time, and reduce production costs. Despite being made from mild steel and stamped components it was considered rugged and its rough appearance didn't hinder its functionality. However, the Leuchtpistole 42 was nearly heavier than its predecessor. Variants * Sturmpistole - The Sturmpistole was a conversion of either Leuchtpistole 34's or Leuchtpistole 42's that added a padded buttstock and sights for firing both lethal and non-lethal roun ...

Anti-tank Grenade
An anti-tank grenade is a specialized hand-thrown grenade used to defeat armored targets. Although their inherently short range limits the usefulness of grenades, troops can lie in ambush or maneuver under cover to exploit the limited outward visibility of the crew in a target vehicle. Hand launched anti-tank grenades became redundant with the introduction of standoff rocket propelled grenades. Grenades were first used against armored vehicles during World War I, but it wasn't until World War II when more effective shaped charge anti-tank grenades were produced. AT grenades are unable to penetrate the armor of modern tanks, but may still damage lighter vehicles. History The first anti-tank grenades were improvised devices. During World War I the Germans were the first to come up with an improvised anti-tank grenade by taking their regular "potato masher" stick grenade and taping two or three more high explosive heads to create one larger grenade. In combat, after arming, the gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
