Barnitzke Machine Gun
The Barnitzke machine gun is a prototype machine gun of late World War II German origin. The weapon uses an unusual delayed blowback operation, where during firing the bolt opening is delayed by the rotational inertia of two flywheels, which are driven by a rack and pinion arrangement on the bolt carrier.

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] |
Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delayed Blowback
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operation. ...

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

MG 42
The MG 42 (shortened from German: ''Maschinengewehr 42'', or "machine gun 42") is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II. Designed to use the standard German 7.92×57mm Mauser rifle round, be low-cost and easier to mass-produce, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges, averaging about 1,200 rounds per minute compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the M1919 Browning, FM 24/29 or Bren gun. This ability made it extremely effective in providing suppressive fire, and its unique sound led to it being ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG 81 Machine Gun
The MG 81 was a German belt fed 7.92×57mm Mauser machine gun which was used in flexible installations in World War II Luftwaffe aircraft, in which capacity it replaced the older drum magazine-fed MG 15. The MG 81 was developed by Mauser as a derivative of their successful MG 34 general-purpose machine gun. Development focus was to reduce production cost and time and to optimize the machine gun for use in aircraft. Developed in 1938/1939, it was in production from 1940 to 1945. A special twin-mount MG 81Z (the Z suffix stands for ''Zwilling'', meaning "twin") was introduced in 1942. It paired up two of the weapons on one mount to provide even more firepower with a maximum cyclic rate of fire of 3,200 rounds per minute without requiring much more space than a standard machine gun. Towards the end of the war many specimens were delivered to the army and equipped for use in ground battles with shoulder rest and bipod. Applications The MG 81Z was found in many unique installations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MGD PM-9
The MGD PM-9 was a French open bolt submachine gun, designed in the late 1940s or early 1950s by Louis Debuit and manufactured in small numbers by French firm Merlin and Gerin in the 1950s. The PM9 was an unusual design in three different ways: it employed off-axis delayed blowback, it had a clock-style spiral mainspring similar to that of the Lewis gun, rather than the cylindrically-coiled spring used in the vast majority of self-loading firearms and, most unconventionally of all, used a rotating flywheel as a delaying mass in conjunction with the bolt. It was furnished with a folding magazine, and some also had folding buttstocks, and this together with its original operating mechanism results in a highly compact weapon, but there is no known record of it being purchased or deployed by any military or police force.

Machine Guns Of Germany
A machine is a physical system using power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and control component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
