MK 115 Cannon
The MK 115 (German: ''Maschinenkanone 115''—"machine cannon 115") was an autocannon developed in Germany in late World War II by Rheinmetall-Borsig for use in aircraft. It was an unusual development in that although it employed a locked breech, it also used a funnel to allow some of the propellant gases to escape out the rear in order to reduce recoil when firing, essentially being an automatic recoilless rifle. The MK 115 was chambered for a 5.5 cm round (in common with a few other late-war German designs), but used a partially combustible cartridge, leaving only the base of the cartridge to eject. The MK 115 was a gas-operated, belt-fed weapon, and its breechblock used a swinging lock mechanism. It had a rifled barrel with an 8°30′ twist. A single prototype in the late stages of development was captured by the Western allies.George Chinn 1951, The Machine Gun: Development During World War II and Korean Conflict by the United States and their Allies of Full Automatic Machi ...

Rheinmetall
Rheinmetall AG is a German automotive and arms manufacturer, headquartered in Düsseldorf, Germany. Its shares are traded on the Frankfurt stock exchange. History Rheinmetall was founded in 1889. Banker and investor Lorenz Zuckermandel Lorenz Zuckermandel (18 February 1847 – 6 January 1928) was a German banker, investor, founder and translator, among other things, of Dante Alighieri's Divine Comedy. Thanks to his many talents, he worked his way from being the poor son of a ... (1847–1928) was one of the founders and the first chairman of the supervisory board. It manufactured steel products, including armaments. During the post-WWI disarmament of Germany, the company diversified, but by the 1930s armament manufacture resumed. In 1933, it acquired A.

August Borsig
Johann Karl Friedrich August Borsig (23 June 1804 – 6 July 1854) was a German businessman who founded the ''Borsig-Werke'' factory. Borsig was born in Breslau (Wrocław), the son of cuirassier and carpenter foreman Johann George Borsig. After learning his father's trade, he first attended the ''Königliche Provinzial-Kunst- und Bauschule'' (Royal Provincial Art and Building school), then until fall of 1825 the ''Königliche Gewerbe-Institut'' (Royal Institute of Trade). He received his practical training in engine construction at the ''Neue Berliner Eisengießerei'' (New Iron Foundry of Berlin) of F. A. Egells, where one of his first tasks was the assembly of a steam engine in Waldenburg, Silesia. After the successful completion of this task, Borsig was made factory manager for eight years. In 1828, he married Louise Pahl; they had one son, Albert. August Borsig and his company From early on, Borsig was a supporter of railroads. Despite the lack of experience with railroads ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil Recoil (often called knockback, kickback o ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded 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 Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Recoilless Rifle
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] |
Breechblock
A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge. Breechblocks are categorised by the type or design of the mechanism by which it is locked or closed for firing. The firearm action more fully refers to the mechanism by which the operator actuates the opening and closing of the breech. Variants A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm. Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the trigger mechanism. A breechblock is a separate compone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Chinn
George Morgan Chinn (January 15, 1902September 4, 1987) was an American weapons expert and soldier. He attended Centre College, and played on the 1921 Centre Praying Colonels football team, which won the national championship. Chinn then opened a diner in a cave, known as 'The Cave House', which also functioned as an underground gambling center. He served as the bodyguard of Happy Chandler while he was governor of Kentucky. Chinn was also Sergeant of Arms for the Kentucky Legislature. Later he was the production line inspector for several weapons' manufacturers, and eventually, a United States Marine Corps, Marine. He designed the Mk 19 grenade launcher. Eventually one of the United States's premier arms experts, Bill Bright said of him "He did for military weapons what Wozniak and Gates did for computers. He added the right pieces to make them reliable and usable. He was what was then called a garage (in his case, cave) inventor." Chin retired to become director of the Kentucky Hi ...

MK 112 Cannon
The MK 108 (German: ''Maschinenkanone''—"machine cannon") was a 30 mm caliber autocannon manufactured in Germany during World War II by Rheinmetall‑Borsig for use in aircraft. The cannon saw widespread use as an anti-bomber weapon during the second half of the war, first seen in 1943 in the Bf 110G-2 bomber destroyers and Bf 109G-6/U4. Four MK 108's formed the main armament of the Me 262 the next year. It could be found on some versions or optional mountings on practically every other German fighter of the era. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the ''Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allied heavy bombers appearing over German-controlled regions by then. Testing verified that the autocannon was well suited to this role, requiring on average just 4 hits with its 85g RDX-load (in a 330g shell) and a r ...
