Adaptiv
Adaptiv is an active camouflage technology developed by BAE Systems AB to protect military vehicles from detection by far infrared night vision devices, providing infrared stealth. It consists of an array of hexagonal Peltier plates which can be rapidly heated and cooled to form any desired image, such as of the natural background or of a non-target object. Its goal is to develop stealth ground vehicles. Technology In 2011, BAE Systems announced their ''Adaptiv'' infrared military camouflage technology, likening it to "a thermal TV screen". It uses about 1000 hexagonal panels to cover the sides of an armoured vehicle such as a tank or personnel carrier. Infrared cameras continuously gather thermal images of the vehicle's surroundings. The Peltier plate panels are rapidly heated and cooled to match either the temperature of the background, such as a forest, or one of the objects in the thermal cloaking system's "library" such as a truck, car or large rock. The system is able t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Active Camouflage
Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual detection. Active camouflage is used in several groups of animals, including reptiles on land, and cephalopod molluscs and flatfish in the sea. Animals achieve active camouflage both by color change and (among marine animals such as squid) by counter-illumination, with the use of bioluminescence. Military counter-illumination camouflage was first investigated during the Second World War for marine use. More recent research has aimed to achieve crypsis by using cameras to sense the visible background, and by controlling Peltier panels or coatings that can vary their appearance. In animals Active camouflage is used in several groups of animals including cephalopod molluscs, fish, and reptiles. There are two mechanisms of active camouflage in ani ...

Military Camouflage
Military camouflage is the use of camouflage by an armed force to protect personnel and equipment from observation by enemy forces. In practice, this means applying colour and materials to military equipment of all kinds, including vehicles, ships, aircraft, gun positions and battledress, either to conceal it from observation ( crypsis), or to make it appear as something else (mimicry). The French slang word ''camouflage'' came into common English usage during World War I when the concept of visual deception developed into an essential part of modern military tactics. In that war, long-range artillery and observation from the air combined to expand the field of fire, and camouflage was widely used to decrease the danger of being targeted or to enable surprise. As such, military camouflage is a form of military deception. Camouflage was first practiced in simple form in the mid 18th century by rifle units. Their tasks required them to be inconspicuous, and they were issued gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BAE Systems AB
BAE Systems AB is a Swedish defence company and a subsidiary of BAE Systems Land & Armaments, whose ultimate parent is the British defence contractor BAE Systems. The company is a holding company for Land Systems Hägglunds AB and BAE Systems Bofors AB, and has no products of its own. Subsidiaries BAE Systems Hägglunds ''AB Hägglund & Söner'' was founded in 1899 by Johan Hägglund in Gullänget, Örnsköldsvik, Sweden. The company was divided in 1988, one part being ''Hägglunds Vehicle AB'', the military vehicles business. In October 1997 the British company Alvis plc acquired Hägglunds Vehicle AB to form Alvis Hägglunds AB. Alvis expanded its military vehicle business in 1998 with the purchase of GKN's armoured vehicle division in 1998 and Vickers Defence in 2002 to form Alvis Vickers. In September 2004 BAE Systems acquired Alvis Vickers and merged it with its RO Defence ordnance division to form BAE Systems Land Systems. Hägglunds was renamed Land Systems Hägglunds. In ...

Combat Vehicle 90
The Combat Vehicle 90 (CV90; Sw. ''Stridsfordon'' 90, Strf90) is a family of Swedish tracked combat vehicles designed by Sweden's Defence Materiel Administration (''Försvarets Materielverk'', FMV), Hägglunds and Bofors during the mid-1980s to early 1990s, entering service in Sweden in the mid-1990s. The CV90 platform design has continuously evolved in steps from Mk0 to current MkIV with advances in technology and in response to changing battlefield requirements. The Swedish version of the main infantry fighting vehicle (IFV) is fitted with a turret from Bofors that is equipped with a 40 mm Bofors autocannon. Export versions are fitted with Hägglunds E-series turrets, armed with either a 30 mm Mk44 or a 35 mm Bushmaster autocannon. Developed specifically for the Nordic subarctic climate, the vehicle has very good mobility in snow and wetlands while carrying and supporting eight, later versions six, fully equipped dismounted soldiers. Other variants include Forward ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stealth Ground Vehicle
Ground vehicles using stealth technology have come to fruition at various times in history. The Swedish Stridsvagn 103 was designed with a low profile to decrease chances of being detected. The Chieftain SID (Signature Integration Demonstrator) was a first British effort in stealth tank technology. The Challenger 2 features a redesigned hull and turret offering lower radar cross section over its predecessor. More recently, the joint U.S./British Future Scout Cavalry System concept was experimented with and appeared in prototype form before being canceled. Other vehicles, particularly unmanned ground vehicles, may unintentionally have an undetectably low radar signature due to their small size. Various coatings and radar absorbing layers of material are available for combat vehicles. The Armored Gun System program of the 1980s attempted to create a stealth vehicle. One of the competitors, the Stingray light tank later became Thailand's light tank. The M1A2 Abrams was also orig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crypsis
In ecology, crypsis is the ability of an animal or a plant to avoid observation or detection by other animals. It may be a predation strategy or an antipredator adaptation. Methods include camouflage, nocturnality, subterranean lifestyle and mimicry. Crypsis can involve visual, olfactory (with pheromones) or auditory concealment. When it is visual, the term cryptic coloration, effectively a synonym for animal camouflage, is sometimes used, but many different methods of camouflage are employed by animals or plants. Overview There is a strong evolutionary pressure for animals to blend into their environment or conceal their shape, for prey animals to avoid predators and for predators to be able to avoid detection by prey. Exceptions include large herbivores without natural enemies, brilliantly colored birds that rely on flight to escape predators, and venomous or otherwise powerfully armed animals with warning coloration. Cryptic animals include the tawny frogmouth (feather pat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infantry Fighting Vehicle
An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit. Infantry fighting vehicles are distinct from armored personnel carriers (APCs), which are transport vehicles armed only for self-defense and not specifically engineered to fight on their own. IFVs are designed to be more mobile than tanks and are equipped with a rapid-firing autocannon or a large conventional gun; they may include side po ...

Vehicle Armour
Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against impacts from micrometeoroids or fragments of space debris. Modern aircraft powered by jet engines usually have them fitted with a sort of armour in the form of an aramid composite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mimesis
Mimesis (; grc, μίμησις, ''mīmēsis'') is a term used in literary criticism and philosophy that carries a wide range of meanings, including ''imitatio'', imitation, nonsensuous similarity, receptivity, representation, mimicry, the act of expression, the act of resembling, and the presentation of the self. The original Ancient Greek term ''mīmēsis'' ( grc, μίμησις, label=none) derives from ''mīmeisthai'' ( grc, μιμεῖσθαι, label=none, 'to imitate'), itself coming from ''mimos'' ( μῖμος, 'imitator, actor'). In ancient Greece, ''mīmēsis'' was an idea that governed the creation of works of art, in particular, with correspondence to the physical world understood as a model for beauty, truth, and the good. Plato contrasted ''mimesis'', or imitation Imitation (from Latin ''imitatio'', "a copying, imitation") is a behavior whereby an individual observes and replicates another's behavior.
