Type 2 Rifle Grenade Launcher
The Type 2 rifle grenade launcher was an attachment for the Japanese Type 38 and Type 99 rifles that allowed them to fire special hollow charge grenades. It was a version of the German Schiessbecher grenade launcher. Two grenades were produced for the launcher: a 30 mm calibre grenade and a larger 40 mm calibre grenade, both designated Type 2. The launcher sits over the end of the barrel, held in place with a clamping device. A special crimped blank cartridge or wooden bullet is used to fire the grenades. The rear of the grenades is pre-rifled to mate with the 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 pro ... in the launcher. The rifling ensures that the grenade is spun in flight, giving it stability and arming the rotational fuze. Both grenades use a largely id ...

Type 38 Rifle
The is a bolt-action service rifle that was used by the Empire of Japan predominantly during the Second Sino-Japanese War and Second World War. The design was adopted by the Imperial Japanese Army in 1905 (the 38th year of the Meiji period, hence "Type 38"). Due to a lack of power in its 6.5×50mmSR Arisaka cartridge, it was partially replaced during the war with the Type 99 rifle, but both rifles saw usage until the end of the war. History and development The Imperial Japanese Army introduced the Type 30 rifle in 1897. However, the weapon had numerous shortcomings, which were highlighted by combat experience in the early stages of the Russo-Japanese War. These included bursting cartridges, a poorly designed lock in which excess gunpowder tended to accumulate, burning the face of the shooter, frequent misfires, jamming, difficulty in cleaning, and cartridge extraction. Major Kijiro Nambu undertook a redesign of the Type 30, which was introduced in 1906. Nambu reduced the number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 99 Rifle
The was a bolt-action rifle of the Arisaka design used by the Imperial Japanese Army during World War II. History During the Second Sino-Japanese War in the 1930s, the Japanese soon found that the 7.7mm cartridge being fired by their Type 92 heavy machine gun in China was superior to the 6.5×50mm cartridge of the Type 38 rifle. This necessitated the development of a new weapon to replace the outclassed Type 38, and finally standardize on a single rifle cartridge. The Imperial Japanese Army (IJA) developed the Type 99 based on the Type 38 rifle but with a caliber of 7.7mm. The Type 99 was produced at nine different arsenals. Seven arsenals were located in Japan, with the other two located at Mukden in Manchukuo and Jinsen in Korea. The IJA had intended to completely replace the Type 38 with the Type 99 by the end of the war. However, the outbreak of the Pacific war never allowed the army to completely replace the Type 38 and so the IJA used both rifles extensively during the w ...

Hollow Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significa ...

Grenades
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a 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 striker to trigger the detonator, and a safety lever secured by a 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 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, anti-tank and stun grenades), chemical aerosols (smoke and gas grenades) or fire (incendiary grenades). Fragmentation grenades ("frags") are probably the most common in modern armies, and when the word ''gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schiessbecher
The Schiessbecher (alternatively: ''Schießbecher'') - literally "shooting cup" - was a German grenade launcher of World War II. A ''Gewehrgranatgerät'' ("rifle grenade device") based on rifle grenade launcher models designed during World War I it fitted to the end of a rifle, the grenade being propelled by a special rifle cartridge. The ''Schiessbecher'' was introduced in 1942 and intended to replace all previous rifle grenade launcher models in use by German armed forces. The ''Schiessbecher'' rifle grenade launcher could be used against infantry, fortifications and light armored vehicles up to a range of . For these differing tasks several specialized grenades with accompanying special propelling cartridges were developed for the ''Schiessbecher''. The rifle grenade propelling cartridges fired a wooden projectile through the barrel to the rifle grenade that upon impact automatically primed the rifle grenade. The ''Schiessbecher'' had a short rifled barrel with a caliber of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Trinitrotoluene
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive that i ...

World War II Infantry Weapons Of Japan
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ...
