Coaxial Machine Gun
A weapon mount is an assembly or mechanism used to hold a weapon (typically a gun) onto a platform in order for it to function at maximum capacity. Weapon mounts can be broken down into two categories: static mounts and non-static mounts. Static mount A static mount is a non-portable weapon support component either mounted directly to the ground, on a fortification, or as part of a vehicle. Turret A gun turret protects the crew or mechanism of a weapon and at the same time lets the weapon be aimed and fired in many directions. A turret is a rotating weapon platform, strictly one that crosses the armour of whatever it is mounted on with a structure called a barbette (on ships) or basket (on tanks) and has a protective structure on top (gunhouse). If it has no gunhouse it is a barbette, if it has no barbette (ie, it is mounted to the outside of the vehicle's armour) it is an installation. Turrets are typically used to mount machine guns, autocannons or large-calibre guns. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanism (engineering)
In engineering, a mechanism is a Machine, device that transforms input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components which may include: * Gears and gear trains; * belt drive, Belts and chain drives; * Cams and cam follower, followers; * Linkage (mechanical), Linkages; * Friction devices, such as brakes or clutches; * Structural components such as a frame, fasteners, bearings, springs, or lubricants; * Various machine elements, such as splines, pins, or keys. The German scientist Franz Reuleaux defines ''machine'' as "a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motion". In this context, his use of ''machine'' is generally interpreted to mean ''mechanism''. The combination of force and movement defines Power (physics), power, and a mechanism manages power to achieve a desired set of forces and ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter-weight composite armor allowed the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. Through the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armored fighting vehicles. Main battle tanks are a key component of modern armies.#House1984, House (1984), ''Toward Combined Arms Warfare: A Survey of 20th-Century Tactics, Doctrine, and Organization'' Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in inf ...

Shoulder Stock
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ball Joint
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. They bionically resemble the ball-and-socket joints found in most tetrapod animals. A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are made of steel. The bearing stud is tapered and threaded, and fits into a tapered hole in the steering knuckle. A protective encasing prevents dirt from getting into the joint assembly. Usually, this is a rubber-like boot that allows movement and expansion of lubricant. Motion-control ball joints tend to be retained with an internal spring, which helps to prevent vibration problems in the linkage. The "offset" ball joint provides means of movement in systems where thermal expansion and contraction, shock, seismic motion, and torsional motions, and forces are present. Theory A ball joint is used for allowing free rotation in two planes at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swivel
A swivel is a connection that allows the connected object, such as a gun, chair, swivel caster, or an anchor rode to rotate horizontally or vertically. Swivel designs A common design for a swivel is a cylindrical rod that can turn freely within a support structure. The rod is usually prevented from slipping out by a nut, washer or thickening of the rod. The device can be attached to the ends of the rod or the center. Another common design is a sphere that is able to rotate within a support structure. The device is attached to the sphere. A third design is a hollow cylindrical rod that has a rod that is slightly smaller than its inside diameter inside of it. They are prevented from coming apart by flanges. The device may be attached to either end. A swivel joint for a pipe is often a threaded connection in between which at least one of the pipes is curved, often at an angle of 45 or 90 degrees. The connection is tightened enough to be water- or air-tight and then tightened f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hardpoint
A hardpoint is an attachment location on a structural frame designed to transfer force and carry an external or internal load. The term is usually used to refer to the mounting points (more formally known as a weapon station or station) on the airframe of military aircrafts that carry weapons (e.g. gun pods and rocket pods), ordnances (bombs and missiles) and support equipments (e.g. flares and countermeasures, targeting pods or drop tanks), and also include hardpoints (also known as pylons) on the wings or fuselage of a military transport aircraft, commercial airliner or private jet where external turbofan jet engines are often mounted. Aircraft In aeronautics, the term ''station'' is used to refer to a point of carriage on the frame of an aircraft. A station is usually rated to carry a certain amount of payload. It is a design number which already has taken the rated g-forces of the frame into account. Therefore, point loads on the structure from externally or internally mo ...

Stridsvagn 103
The Stridsvagn 103 (Strv 103), also known as the Alternative S and S-tank, is a Swedish post-World War II main battle tank, designed and manufactured in Sweden. "Strv" is the Swedish military abbreviation of ''stridsvagn'', Swedish for chariot and tank (literally ''combat carriage''), while the ''103'' comes from being the third tank in Swedish service to be equipped with a 10 cm gun. Developed in the 1950s, it was the first main battle tank to use a gas turbine engine and the only mass-produced tank since World War II to dispense with a turret besides the German Kanonenjagdpanzer. It has an unconventional design with a unique gun laying process: it is turretless with a fixed gun traversed by engaging the tracks (like the 75 mm gun on the 1930s French Char B1) and elevated by adjusting the hull suspension. The result was a very low-profile design with an emphasis on survivability and heightened crew protection level. Strv 103s formed a major portion of the Swedish armoured ...

AC-47 Spooky
The Douglas AC-47 Spooky (also nicknamed "Puff, the Magic Dragon") was the first in a series of fixed-wing gunships developed by the United States Air Force during the Vietnam War. It was designed to provide more firepower than light and medium ground-attack aircraft in certain situations when ground forces called for close air support. Design and development The AC-47 was a United States Air Force (USAF) C-47, (the military version of the DC-3) that had been modified by mounting three 7.62 mm General Electric miniguns to fire through two rear window openings and the side cargo door, all on the left (pilot's) side of the aircraft, to provide close air support for ground troops. Other armament configurations could also be found on similar C-47-based aircraft around the world. The guns were actuated by a control on the pilot's yoke whereby he could control the guns either individually or together, although gunners were also among the crew to assist with gun failures and ...

Schräge Musik
''Schräge Musik'', which may also be spelled ''Schraege Musik'', was a common name for the fitting of an upward-firing autocannon or machine gun, to an interceptor aircraft, interceptor aircraft, such as a night fighter. The term was introduced by the Nazi Germany, German ''Luftwaffe'' during World War II. "''Schräge Musik''" was previously a German language, German colloquialism, meaning music that featured an unusual Musical tuning, tuning and/or time signature. By itself, the word ''Schräge'' has often been translated as "wikt#Adjective, slanting" or "Oblique angle, oblique", although it may instead be rendered into English as "weird" or "strange". The first such systems were developed in World War I. They were also developed and used by the Japanese military during World War II. Like the ''Luftwaffe'', the Imperial Japanese Navy Air Service (IJNAS) and Imperial Japanese Army Air Service (IJAAS) fitted such weapons to twin-engined night fighters. Both the Luftwaffe an ...

Spotting Rifle
A spotting rifle or ranging gun is a small-calibre rifle used as a sighting device for artillery. The ballistics of the spotting rifle are matched to those of the artillery piece, so that if a shot from the spotting rifle lands on the target, it may be assumed that the main weapon will also do so. Anti-tank recoilless rifles Spotting rifles were most commonly used with recoilless rifles as anti-tank artillery, from the 1950s to the 1970s. These weapons are used for direct fire with line-of-sight visibility to the target. As recoilless rifles have a relatively low muzzle velocity and thus a high trajectory, accurate ranging is important An optical sight can measure the bearing to a target, but not easily or accurately measure the range. Optical rangefinders were too large for lightweight portable artillery, and the later development of laser rangefinders would in turn make spotting rifles obsolete. The British BAT series of 120 mm anti-tank recoilless rifles used a variet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mk 153 Shoulder-Launched Multipurpose Assault Weapon
The Mk 153 Shoulder-Launched Multipurpose Assault Weapon (SMAW) is a smoothbore shoulder-fired rocket launcher. It is a portable assault weapon (i.e. bunker buster) and has a secondary anti-armor capability. Developed from the B-300, it was introduced to the United States Armed Forces in 1984. It has a maximum effective range of against a tank-sized target. It can be used to destroy bunkers and other fortifications during assault operations; it can also destroy other designated targets using the dual mode rocket, and main battle tanks using the high-explosive anti-tank rocket. Operations in Afghanistan and Iraq saw a thermobaric rocket added (described as a "Novel Explosive" (NE)), which is capable of collapsing a building. Service history The SMAW system (launcher, ammunition and logistics support) was fielded in 1984 as a United States Marine Corps–unique system. The Mod 0 demonstrated several shortcomings, resulting in a series of modifications in the mid-2000s. These modi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
