20×82mm
The 20×82mm (sometimes 20×82mm Mauser) is a German 20 mm caliber Cartridge (firearms), cartridge developed during World War II for the MG 151/20 cannon. It continues to see usage today with the South-African Vektor GA-1 autocannon and Denel NTW-20 anti-material rifle and some remaining users of the MG 151/20. Usage The cartridge was developed in Nazi Germany during World War II as a necked-up 20 mm variant of the 15×96mm cartridge in use with the MG 151/15 heavy aircraft machinegun. The 15 mm caliber proved to be insufficient for aircraft use and it was thus decided to redevelope the cartridge into 20 mm caliber, by shortening and necking-up the casing, and installing the 20 mm mine shells of the MG FF cannon, MG FF/M. By necking up the existing cartridge, the MG 151/15 guns could easily be converted by a barrel switch, creating the MG 151/20. Beyond the MG 151/20, the 20×82mm was also used in the MG 210 cannon, an attempt by Mauser to improve on the rate of fire ...

Denel NTW-20
The NTW-20 is a South African anti-materiel rifle, developed by Denel Mechem in the 1990s. It is intended for deployment against targets including parked aircraft, telecommunication masts, power lines, missile sites, radar installations, refineries, satellite dishes, gun emplacements, bunkers, and personnel, using a range of specialised projectiles. Development The weapon was designed by Tony Neophytou (co-designer of the Neostead combat shotgun). Development of the system began in August 1995 under the "Aerotek" name and a working prototype was ready for testing four and a half months later. This rapid progress was made possible by Neophytou's expertise in the field of recoil reduction systems, having worked on helicopter turrets in the past. To further reduce the amount of research and development, the project recycled the barrel, bolt and barrel extension of the existing Vektor GA-1, Vektor GA1 automatic cannon. It was put into production by Denel Land Systems in two version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG 151/20
The ''Maschinengewehr'' (MG) 151 is a belt-fed autocannon for aircraft use, developed in Nazi Germany from 1934 to 1940 and produced by Waffenfabrik Mauser during World War II. It was originally produced in 15.1 mm caliber from 1940, with a 15×96mm cartridge, but due to demand for higher effect against aircraft, especially with the introduction of mine shells for the 20 mm MG-FF/M aircraft cannon, the design was rechambered to 20 mm caliber in 1941, using a newly developed 20×82mm cartridge which traded projectile velocity for explosive power. The initial 15 mm variant then became known as the MG 151/15, with the new 20 mm variant becoming the MG 151/20. The MG 151/20 cannon was widely used on German Luftwaffe combat aircraft throughout World War II, mainly as offensive armament, but also seeing some use as defensive guns. Existing MG 151/15 guns saw use as aircraft armament throughout the war, albeit more limited compared to the MG 151/20, but also as a ...

Vektor GA-1
The Denel Vektor GA-1 is an automatic cannon based on the German WWII MG 151/20 automatic cannon. Compared to other rapid-fire 20 mm autocannons, it is lightweight and has low recoil due to its design and the use of the 20×82mm The 20×82mm (sometimes 20×82mm Mauser) is a German 20 mm caliber Cartridge (firearms), cartridge developed during World War II for the MG 151/20 cannon.

Neopup PAW-20
The Neopup PAW-20 (Personal Assault Weapon, 20 mm) is a 20×42mm semi-automatic grenade launcher designed by Tony Neophytou and as of 2015, is produced and marketed by Denel. Overview The PAW-20 is a hand-held, semi-automatic direct fire grenade launcher that fires a 20×42mm point-detonating round. It holds six rounds in a detachable rotary magazine, with an effective range of 300–400 meters. It was designed mainly as an anti-personnel grenade launcher for use against opposition closely grouped together or behind light cover. However, it is also compatible with less-than-lethal ammunition. The PAW-20 is in direct competition with the more complicated and expensive joint German-U.S. XM25 CDTE and Korean S&T Daewoo K11. The PAW-20 has attracted some criticism due to the location of the ejection port. On slow motion footage it can be seen that ejection happens after the hydraulic buffer is fully contracted, which brings the ejection port right to shooters face. Due t ...

Nazi Germany
Nazi Germany, officially known as the German Reich and later the Greater German Reich, was the German Reich, German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a Totalitarianism, totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after 12 years, when the Allies of World War II, Allies defeated Germany and entered the capital, Berlin, End of World War II in Europe, ending World War II in Europe. After Hitler was appointed Chancellor of Germany in 1933, the Nazi Party began to eliminate political opposition and consolidate power. A 1934 German referendum confirmed Hitler as sole ''Führer'' (leader). Power was centralised in Hitler's person, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PETN
Pentaerythritol tetranitrate (PETN), also known as PENT, pentyl, PENTA (''ПЕНТА'', primarily in Russian), TEN (tetraeritrit nitrate), corpent, or penthrite (or, rarely and primarily in German, as ''nitropenta''), is an explosive material. It is the nitrate ester of pentaerythritol, and is structurally very similar to nitroglycerin. Penta refers to the five carbon atoms of the neopentane skeleton. PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive. Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. History Pentaerythritol tetranitrate was first prepared and patented in 1894 by the explosives manufacturer of Cologne, Germany. The production of PETN started in 1912, when the improved method of production was patented by the German government. PETN was used by ...

Blasting Cap
A detonator is a device used to make an explosive or explosive device explode. Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages. Types of detonators include non-electric and electric. Non-electric detonators are typically stab or Pyrotechnics, pyrotechnic while electric are typically "hot wire" (low voltage), exploding bridge wire (high voltage) or explosive foil (very high voltage). The original electric detonators invented in 1875 independently by Julius Smith and Perry Gardiner used mercury fulminate as the primary explosive. Around the turn of the century performance was enhanced in the Smith-Gardiner blasting cap by the addition of 10-20% potassium chlorate. This compound was superseded by others: lead azide, lead styphnate, some aluminium, or other materials such as DDNP (diazo dinitro phenol) to reduce the amount of lead emitted in ...

Lead Azide
Lead(II) azide is an inorganic compound. More so than other azides, it is explosive. It is used in detonators to initiate secondary explosives. In a commercially usable form, it is a white to buff powder. Preparation and handling Lead(II) azide is prepared by the reaction of sodium azide and lead(II) nitrate in aqueous solution. Lead(II) acetate can also be used. Thickeners such as dextrin or polyvinyl alcohol are often added to the solution to stabilize the precipitated product. In fact, it is normally shipped in a dextrinated solution that lowers its sensitivity. Production history Lead azide in its pure form was first prepared by Theodor Curtius in 1891. Due to sensitivity and stability concerns, the dextrinated form of lead azide (MIL-L-3055) was developed in the 1920s and 1930s with large scale production by DuPont Co beginning in 1932. Detonator development during World War II resulted in the need for a form of lead azide with a more brisant output. RD-1333 lead ...
