SKZ
A recoilless rifle, recoilless launcher or recoilless gun, sometimes abbreviated "RR" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants (which can be fin-stabilized or unstabilized) are recoilless guns. This distinction is often lost, and both are often called recoilless rifles. Though sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alfred Krupp
Alfred Krupp (born ''Alfried Felix Alwyn Krupp''; Essen, 26 April 1812 – Essen, 14 July 1887) was a German steel manufacturer and inventor; the largest arms supplier of his era, which earned him the nickname "The Cannon King". Biography Alfred Krupp, son of Friedrich Krupp and his wife Theresa Helena Johann Wilhelmi (1790-1850), was born in 1812. His father did not manage to put the factory he founded in 1811 on its feet during his lifetime. He died in 1826 when Alfred Krupp was 14 years old and left to his son the secret of making high-quality cast steel, together with a small workshop in which production had come almost to a standstill. At this time, the family lived with the aunt in Metternich. The company, which at that time had only seven jobs and a debt of 10,000 thalers, was inherited by Friedrich's wife Theresa. Together with Friedrich Krupp's sister, Helena von Müller, née Krupp, a steel company was founded. The founding agreement was signed by all the heirs of Fr ...

Leonardo Da Vinci
Leonardo di ser Piero da Vinci (15 April 14522 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, Drawing, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he also became known for #Journals and notes, his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanism, Renaissance humanist ideal, and his List of works by Leonardo da Vinci, collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo. Born Legitimacy (family law), out of wedlock to a successful Civil law notary, notary and a lower-class woman in, or near, Vinci, Tuscany, Vinci, he was educated in Florence by the Italian painter and sculptor ...

Air Resistance
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armbrust
Armbrust (German: ''Crossbow'') is a lightweight unguided anti-tank weapon designed and developed by Messerschmitt-Bölkow-Blohm of Germany, who later sold its manufacturing rights to Chartered Industries of Singapore (the predecessor of ST Kinetics). Overview The Armbrust is a recoilless weapon, and is one of the few weapons of this kind that may safely be fired in an enclosed space. The propellant charge is placed between two pistons with the projectile in front of one and a mass of shredded plastic in the rear. Unlike most recoilless weapons, it is a true counter-shot weapon, as the mass of the projectile is equal to the mass of the counterweight and they are ejected from the barrel at the same initial velocity. When the weapon is fired, the propellant expands, pushing the two pistons out. The projectile is forced out of the front and the plastic out of the back. The plastic disperses on leaving the back of the barrel, and is quickly stopped by air resistance. The pistons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backblast Area
The backblast area is a cone-shaped area behind a rocket launcher, rocket-assisted takeoff unit or recoilless rifle, where hot gases are expelled when the rocket or rifle is discharged. The backblast area is dangerous to ground personnel, who may be burned by the gases or exposed to overpressure caused by the explosion. In confined spaces, common in urban warfare, even the operators themselves may be at risk due to deflection of backblast by walls or sturdier civilian vehicles behind them. Soft launch methods diminish backblast by ejecting the projectile some distance before its main rocket motor ignites. Backblast can also be reduced by adding a countermass that is expelled out the rear of the weapon. For example, the AT4-CS (confined space variant) uses saltwater, along with a lower-velocity projectile.

MATADOR
A bullfighter (or matador) is a performer in the activity of bullfighting. ''Torero'' () or ''toureiro'' (), both from Latin ''taurarius'', are the Spanish and Portuguese words for bullfighter and describe all the performers in the activity of bullfighting as practised in Spain, Portugal, Mexico, Peru, France, Colombia, Ecuador, Venezuela and other countries influenced by Portuguese and Spanish culture. The main performer and leader of the entourage in a bullfight, and who finally kills the bull, is addressed as ''maestro'' (master), or with the formal title ''matador de toros'' (killer of bulls). The other bullfighters in the entourage are called ''subalternos'' and their suits are embroidered in silver as opposed to the matador's gold. They include the ''picadores'', ''rejoneadores'', and ''banderilleros''. Present since the sport's earliest history, the number of women in bullfighting has steadily increased since the late-19 century, both on foot and on horseback. Usua ...

Panzerfaust 3
The Panzerfaust 3 (lit. "armor fist" or "tank fist") is a modern semi-disposable recoilless anti-tank weapon, which was developed between 1978 and 1985 and first entered service with the Bundeswehr in 1987 (although they did not officially adopt it until 1992). It was first ordered in 1973 to provide West German infantry with an effective weapon against contemporary Soviet armor, thereby replacing West Germany's aging PzF 44 Light Lanze launchers and the heavy Carl Gustaf 84 mm anti-tank recoilless rifle manufactured in Sweden. The Panzerfaust 3 is operated by at least 11 countries and has seen combat in Afghanistan and Ukraine. History The Panzerfaust 3's name dates back to the Panzerfaust used by the German army in World War II, which consisted of a small, disposable preloaded launch tube firing a high-explosive anti-tank (HEAT) warhead, operated by one soldier. The introduction of reactive and active armors on combat vehicles of the then Warsaw Pact countries started a de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPG-7
The RPG-7 (russian: link=no, РПГ-7, Ручной Противотанковый Гранатомёт, Ruchnoy Protivotankoviy Granatomyot) is a portable, reusable, unguided, shoulder-launched, anti-tank, rocket-propelled grenade launcher. The RPG-7 and its predecessor, the RPG-2, were designed by the Soviet Union, and are now manufactured by the Russian company Bazalt. The weapon has the GRAU index (Russian armed forces index) 6G3. The ruggedness, simplicity, low cost, and effectiveness of the RPG-7 has made it the most widely used anti-armor weapon in the world. Currently around 40 countries use the weapon; it is manufactured in several variants by nine countries. It is popular with irregular and guerrilla forces. The RPG has been used in almost all conflicts across the world since the mid-1960s from the Vietnam War to the 2022 Russo-Ukrainian War. Widely produced, the most commonly seen major variations are the RPG-7D (десантник – ''desantnik'' – paratro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
