M270 Multiple Launch Rocket System
The M270 Multiple Launch Rocket System (M270 MLRS) is an American armored self-propelled multiple launch rocket system. The U.S. Army variant of the M270 is based on the chassis of the Bradley Fighting Vehicle. The first M270s were delivered in 1983, and were adopted by several NATO and non-NATO militaries. The platform first saw service with the United States in the 1991 Gulf War. It has received multiple improvements since its inception, including the ability to fire guided missiles. M270s provided by the United Kingdom have seen use in the Russian invasion of Ukraine. Description Background In the early 1970s, the Soviet Union had a clear advantage over U.S. and NATO forces in terms of rocket artillery. Soviet doctrine dictated large-scale bombardment of a target area with large numbers of truck-mounted multiple rocket launchers (MRLs), such as the BM-21 "Grad". By contrast, U.S. artillerists favored conventional large-caliber artillery for its relative accuracy and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

5083 Aluminum Alloy
5083 aluminium alloy is an aluminium–magnesium alloy with magnesium and traces of manganese and chromium. It is highly resistant to attack by seawater and industrial chemicals. Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65 °C. Alloy 5083 is also commonly used in cryogenic applications due to it being able to be cooled to -195°C. At this temperature, the alloy has an increase in ultimate tensile strength of 40% and in yield strength of 10% as well as exhibiting excellent fracture toughness at such temperatures. Anodizing For AA 5083 alloy, the stages of porous structure development are substantially identical with that of pure aluminium, although an increase in oxide growth rate and high conductance of the oxide film were observed. ...

Guided Missiles
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Member States Of NATO
The North Atlantic Treaty Organization (NATO) is an international military alliance consisting of 32 member states from Europe and North America. It was established at the signing of the North Atlantic Treaty on 4 April 1949. Of the 32 member countries, 30 are in Europe and two are in North America. Between 1994 and 1997, wider forums for regional cooperation between NATO and its neighbours were set up, including the Partnership for Peace, the Mediterranean Dialogue initiative, and the Euro-Atlantic Partnership Council. All members have militaries, except for Iceland, which does not have a Military of Iceland, typical army (but it does have a Icelandic Coast Guard, coast guard and a small unit of civilian specialists for NATO operations). Three of NATO's members are List of states with nuclear weapons, nuclear weapons states: France, the United Kingdom, and the United States. NATO has 12 original founding member states. Three more members joined between 1952 and 1955, and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradley Fighting Vehicle
The Bradley Fighting Vehicle (BFV) is an American continuous track, tracked armored fighting vehicle of the United States developed by FMC Corporation and now manufactured by BAE Systems Land & Armaments, formerly United Defense. It is named for U.S. General Omar Bradley. The Bradley is designed to transport infantry or scouts with armor protection, while providing covering fire to suppress enemy troops and armored vehicles. Variants include the M2 Bradley infantry fighting vehicle and the M3 Bradley reconnaissance vehicle. The M2 holds a crew of three—a commander, a gunner and a driver—along with six fully equipped soldiers. The M3 mainly conducts scout missions and carries two Cavalry scout, scout troopers in addition to the regular crew of three, with space for additional BGM-71 TOW missiles. In 2014, the U.S. Army selected BAE Systems' Armored Multi-Purpose Vehicle (AMPV) proposal of a turretless variant of the Bradley to replace over 2,800 M113 armored personnel carrier ...

Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of a manufactured object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. Examples Vehicles In the case of vehicles, the term ''rolling chassis'' means the frame plus the "running gear" like engine, transmission, drive shaft, differential, and suspension. The "rolling chassis" description originated from assembly production when an integrated chassis "rolled on its own tires" just before truck bodies were bolted to the frames near the end of the line. An underbody (sometimes referred to as " coachwork"), which is usually not necessary for the integrity of the structure, is built on the chassis to c ...

Multiple Rocket Launcher
A multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple rocket launcher, launchers which are fixed to a single weapons platform, platform, and shoots its rocket (weapon), rocket ordnance in a fashion similar to a volley gun. Rockets are self-propelled in flight and have different capabilities than conventional artillery shell (projectile), shells, such as longer effective range, lower recoil, typically considerably higher payload than a similarly sized gun artillery platform, or even carrying multiple warheads. Unguided rocket artillery is notoriously inaccurate and slow to reload compared to gun artillery. A multiple rocket launcher helps compensate for this with its ability to launch multiple rockets in rapid succession, which, coupled with the large blast radius, kill zone of each warhead, can easily deliver saturation fire over a target area. However, modern rockets can use GPS or inertial guidance t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Artillery
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and self-propelled rocket artillery. They are high-mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar (weapon), mortar, or some form of rocket (weapon), rocket/missile launcher. They are usually used for long-range indirect-fire, indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and tank destroyers, which were typically well-armoured vehicles often based upon the chassis of a tank. In lieu of the standard tank's general-purpose tank gun, main gun that fired both high-explosive and anti-tank ammunition, direct-fire vehicles had specialized roles, with assault guns providing close fire-supp ...

Armoured Fighting Vehicle
An armoured fighting vehicle (British English) or armored fighting vehicle (American English) (AFV) is an armed combat vehicle protected by vehicle armour, armour, generally combining operational mobility with Offensive (military), offensive and defense (military), defensive capabilities. AFVs can be wheeled or Continuous track, tracked. Examples of AFVs are tanks, armored car (military), armoured cars, assault guns, Self-propelled artillery, self-propelled artilleries, infantry fighting vehicles (IFV), and armoured personnel carriers (APC). Armoured fighting vehicles are classified according to their characteristics and intended role on the battlefield. The classifications are not absolute; two countries may classify the same vehicle differently, and the criteria change over time. For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role. Successful designs are often ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torsion Bar
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M46/M47/M48 Patton, M60 and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...
