Nebelkerzenabwurfvorrichtung
The ''Nebelkerzenabwurfvorrichtung'' (abbreviated N.K.A.V.) was a rear mounted grenade dispenser used to disperse the Schnellnebelkerze 39 smoke grenade. It was typically found on German tanks from 1939 through 1942. Operation The device carried five smoke grenades, each grenade being held in position by spring loaded catches. The vehicle commander released the grenades one at a time by wire control which operated a ratchet coupled to a camshaft. Each pull of the control wire rotated the camshaft one fifth of a turn, releasing a smoke grenade, the pin of which was drawn out by a fixed chain, and the ratchet was returned to its original position by a second spring. Five pulls on the control wire would release all five smoke grenades in succession, enabling the vehicle to reverse out of sight into its own smoke screen with the grenades discharging smoke for about 100 to 200 seconds. Later examples of the ''Nebelkerzenabwurfvorrichtung'' were fully enclosed in an armored box (''N. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nahverteidigungswaffe
The ''Nahverteidigungswaffe'' was a roof mounted, breech-loaded, single shot, multi-purpose, 360 ° rotating grenade launcher that could fire a variety of ammunition. It was typically found on German tanks such as the Panzer IV, Panther I, Tiger I, and Tiger II from 1944 until the end of the war and was intended to replace three previous devices: the '' Nebelwurfgerät'', the '' Minenabwurfvorrichtung'', and pistol ports. Operation The ''Nahverteidigungswaffe'' was a simple breech-loaded launcher tube oriented at a 50° angle and fitted in a traversable mounting on the turret roof. Unlike the previous externally mounted launchers, it was not exposed to enemy fire, being reloaded from within the vehicle through a hinged breech. The ''Nahverteidigungswaffe'' was designed to mate with the standard '' Kampfpistole'' flare gun and could be sealed by an armored plug when not in use. Aiming was by periscopes located on the turret and cupola. Ammunition The device could fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minenabwurfvorrichtung
The ''Minenabwurfvorrichtung'' was an anti-personnel mine launcher used to disperse S-Mines. It was typically found on German tanks such as the Panzer III and Tiger I from 1942 through 1943. Operation The ''Minenabwurfvorrichtung'' was a simple device consisting of a small steel tube oriented at a 50 ° angle mounted to the hull roof or track guards of the tank. The tube contained a modified version of the infantry S-mine equipped with the ''Glühzünder'' 28 fuze which allowed it to be electrically fired from the inside of the vehicle using a small control panel labeled ''Minenabwurfschalter'' that was mounted on the engine firewall. The mine itself consisted of a round projectile deep by wide and contained about 360 steel balls. The projectile was fired about into the air, where it would explode, scattering the steel balls in all directions. Starting in June 1942, up to six launchers were mounted on the track guards of an unknown number of Panzerkampfwagen III ''Ausführun ...

Nebelwurfgerät
The ''Nebelwurfgerät'' was a gun turret, turret mounted grenade launcher, launcher used to disperse the ''Schnellnebelkerze'' 39 smoke grenade. It was typically found on Nazi Germany, German Tanks in the German Army, tanks from 1942 through 1943. Operation The ''Nebelwurfgerät'' was mounted in two sets of three, one on each forward side wall of the turret with each launcher being in Caliber, calibre by in length. The uppermost launcher tubes were oriented forward and angle, angled slightly outwards while the middle and lower tubes were set on a progressively lower elevation but increasing angle. Six smoke grenades were carried, one in each launcher tube. They were ejected out of each tube by Zündschraube C 23 primer (firearms), primer which was electricity, electrically fired from six push-buttons labeled ''Nebelkerzen'', these buttons being grouped in two sets of three, located in the turret to the Left (direction), left and Right (direction), right of the Tank#Crew, comman ...

Smoke Screen
A smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft, or ships. Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or a warship). Whereas smoke screens were originally used to hide movement from enemies' line of sight, modern technology means that they are now also available in new forms; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and they are also available for vehicles in a super-dense form used to block laser beams of enemy target designators or range finders. Technology Smoke grenades These are canister-type grenades used as a ground-to-ground or ground-to-air signalling device. The body consists of a steel sheet metal cylinder with a few emission holes on the top and/or bottom to allow smoke release when the smoke composition inside the grenade is ignited ...

Tanks Of Germany
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, an ...

Grenade Launchers Of Germany
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and a safety lever secured by a cotter pin. The user removes the safety pin before throwing, and once the grenade leaves the hand the safety lever gets released, allowing the striker to trigger a primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (high-explosive, anti-tank and stun grenades), chemical aerosols (smoke and gas grenades) or fire (incendiary grenades). Fragmentation grenades ("frags") are probably the most common in modern armies, and when the word ''grenade' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balkenkreuz
The ''Balkenkreuz'' () is a straight-armed cross that was first introduced in 1916–1918 and later became the emblem of the ''Wehrmacht'' (German Armed Forces) and its branches from 1935 until the end of World War II. It was used by the '' Wehrmacht Heer'' (Army), ''Luftwaffe'' (Air Force), and '' Kriegsmarine'' (Navy). History Germany's ''Luftstreitkräfte'' (the army air service of the German Imperial Army) first officially adopted the ''Balkenkreuz'' in mid-April 1918 (about a week before the death of Manfred von Richthofen), and used it from that time until World War I ended in November 1918. The IdFlieg directive of 20 March 1918 to all manufacturers states in the first sentence (translated to English): "To improve the recognition of our aircraft, the following is ordered: ... In paragraph 2, the second sentence specifies: "This alteration is to be carried out by 15 April 1918." The closing sentence reads: "Order 41390 is to be speedily executed." Its use resumed, with ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armour
Armour (British English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some mostly ground attack combat aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat". The word originates from the Old French , itself derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be co ...
