Synchronization Gear
A synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning Propeller (aeronautics), propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon. Design and experimentation with gun synchronization had been underway in French Third Republic, France and German Empire, Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounti ...

Bundesarchiv Bild 146-2006-0002, Flugzeug Messerschmitt Me 109, Justieren Des MGs
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior (Germany), Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest docum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parabellum MG 14/17
The Parabellum MG 14 was a 8x57 mm IS, 7.92 mm caliber World War I machine gun built by Deutsche Waffen und Munitionsfabriken. It was a redesign of the MG 08, Maschinengewehr 08 machine gun (itself an adaptation of the Maxim gun) system intended for use on aircraft and zeppelins. Design Like the earlier Vickers machine gun, it used a toggle action that broke upwards rather than downwards, the opposite way to the MG 08, making for a much more compact receiver. The fusee spring was replaced with an internal spring design, the breech block was completely different and the spent cartridges dropped out the bottom of the receiver, rather than being ejected forward through a hole under the breech from the receiver. There appear to be no action or receiver parts interchangeable with the MG 08. The MG 08's belt-style ammunition feed was enclosed in a drum, the recoil casing was lightened and the cooling jacket was modified for air- instead of water-cooling. The rate of fire was 700 roun ...

Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm ( fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, and allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger p ...

Open Bolt
A firearm is said to fire from an open bolt or open breech if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that cartridge in the same movement. Like any other self-loading design, the action is cycled by the energy released from the propellant, which sends the bolt back to the rear, compressing the mainspring in readiness for firing the next round. In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns, the trigger and sear do not affect the movement of the bolt directly. Generally, an open-bolt firing cycle is used for fully automatic weapons and not for semi-automatic weapons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiat–Revelli Modello 1914
The Fiat–Revelli Modello 1914 was an Italian water-cooled medium machine gun produced from 1914 to 1918. It was the standard machine-gun of the Italian Army in World War I, and was used in limited numbers into World War II. The ammunition was fed from an awkward large box magazine, which could hold 50 rounds and fired the same 6.5mm round issued for the Carcano rifle. Like many machine guns of that period, it was water cooled and somewhat cumbersome. Overview It was very similar to the Maxim Maxim or Maksim may refer to: Entertainment *Maxim (magazine), ''Maxim'' (magazine), an international men's magazine ** Maxim (Australia), ''Maxim'' (Australia), the Australian edition ** Maxim (India), ''Maxim'' (India), the Indian edition *Maxim ... in appearance (it had a similar-looking water-cooling jacket and tripod), even though its internal workings were entirely different.

Closed Bolt
A semi or full-automatic firearm which is said to fire from a closed bolt or closed breech is one where, when ready to fire, a round is in the chamber and the bolt and working parts are forward ''in battery''. When the trigger is pulled, the firing pin or striker fires the round; the action is cycled by the energy of the shot, sending the bolt to the rear, which extracts and ejects the empty cartridge case; and the bolt goes forward, feeding a fresh round from the magazine into the chamber, ready for the next shot. World War I aircraft When World War I era machine guns were being tried for use on aircraft, the Lewis gun was found not to be usable with a gun synchronizer for forward firing through the propeller, due to its firing cycle starting with an open bolt. Maxim style arms fired with a cycle starting with a closed bolt, and since the bullet firing from the gun started the firing cycle, it was much easier to set the synchronizer to trigger the gun only when the prope ...
