SA-14
The 9K34 Strela-3 (russian: 9К34 «Стрела-3», 'arrow', NATO reporting name: SA-14 Gremlin) is a man-portable air defense missile system ( MANPADS) developed in the Soviet Union as a response to the poor performance of the earlier 9K32 Strela-2 (SA-7 Grail) system. The missile was largely based on the earlier Strela 2, and thus development proceeded rapidly. The new weapon was accepted into service in the Soviet Army in January 1974. Description The most significant change over the Strela 2 was the introduction of an all-new infra-red homing seeker head. The new seeker worked on FM modulation (con-scan) principle, which is less vulnerable to jamming and decoy flares than the earlier AM (spin-scan) seekers, which were easily fooled by flares and even the most primitive infrared jammers. The new seeker also introduced detector element cooling in the form of a pressurized nitrogen bottle attached to the launcher. The effect of cooling was to expand the seeker's lead sulp ...

Man-portable Air-defense Systems
Man-portable air-defense systems (MANPADS or MPADS) are portable surface-to-air missiles. They are guided weapons and are a threat to low-flying aircraft, especially helicopters. Overview MANPADS were developed in the 1950s to provide military ground forces with protection from jet aircraft. They have received a great deal of attention, partly because armed groups have used them against commercial airliners. These missiles, affordable and widely available through a variety of sources, have been used successfully over the past three decades both in military conflicts, as well as by terrorist organizations. Twenty-five countries, including the United Kingdom, the United States, Poland, Sweden, Russia, and Turkey, produce man-portable air defense systems.CRS RL31741 page 1 Possession, export, and trafficking of such weapons is officially tightly controlled, due to the threat they pose to civil aviation, although such efforts have not always been successful.

Baghdad International Airport
Baghdad International Airport , previously Saddam International Airport ( ar, مطار بغداد الدولي, Maṭār Baġdād ad-Dawaliyy) is Iraq's largest international airport, located in a suburb about west of downtown Baghdad in the Baghdad Governorate. It is the home base for Iraq's national airline, Iraqi Airways. History Pre-1982 The airport was developed under a consortium led by French company Spie Batignolles under an agreement made in 1979. The Iran-Iraq war delayed full opening of the airport until 1982. It opened as Saddam International Airport, bearing the name of then-Iraqi President Saddam Hussein. 1991–2003 Most of Baghdad's civilian flights stopped in 1991, when the United Nations imposed restrictions on Iraq after its invasion of Kuwait. After the Persian Gulf War, a no-fly zone imposed on Iraq by the United States and the United Kingdom meant that Iraqi Airways was only able to continue domestic flights for limited periods. Internationally, Baghda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2003 Baghdad DHL Attempted Shootdown Incident
On 22 November 2003, shortly after takeoff from Baghdad, Iraq, an Airbus A300B2-200F cargo plane, registered OO-DLL and owned by European Air Transport (doing business as DHL Express), was struck on the left wing by a surface-to-air missile while on a scheduled flight to Muharraq, Bahrain. Severe wing damage resulted in a fire and complete loss of hydraulic flight control systems. Because outboard left wing fuel tank 1A was full at takeoff, no fuel-air vapour explosion occurred. Liquid jet fuel dropped away as 1A disintegrated. Inboard fuel tank 1 was pierced and leaking. Returning to Baghdad, the three-man crew made an injury-free landing of the seriously damaged A300, using differential engine thrust as the only pilot input. This was despite major damage to a wing, total loss of hydraulic control, a faster-than-safe landing speed, and a ground path that veered off the runway surface and onto unprepared ground.

Jamming (physics)
Jamming is the physical process by which the viscosity of some mesoscopic materials, such as granular materials, glasses, foams, polymers, emulsions, and other complex fluids, increases with increasing particle density. The jamming transition has been proposed as a new type of phase transition, with similarities to a glass transition but very different from the formation of crystalline solids. While a glass transition occurs when the liquid state is cooled, the jamming transition happens when the density, or the packing fraction of the particles, is increased. This crowding of the constituent particles prevents them from flowing under an applied stress and from exploring phase space, thus making the aggregate material behave as a solid. The system may be able to unjam if volume fraction is decreased, or external stresses are applied such that they exceed the yield stress. This transition is interesting because it is nonlinear with respect to volume fraction. The jamming phas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flare
A flare, also sometimes called a fusée, fusee, or bengala in some Latin-speaking countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes. History The earliest recorded use of gunpowder for signaling purposes was the 'signal bomb' used by the Chinese Song Dynasty (960–1279) as the Mongol-led Yuan Dynasty (1271–1368) besieged Yangzhou in 1276. These soft-shelled bombs, timed to explode in midair, were used to send messages to a detachment of troops far in the distance. Another mention of the signal bomb appears in a text dating ...

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming. There are two general classes of radar jamming, mechanical and electronic. Mechanical jamming entails reflecting enemy radio signals in various ways to provide false or misleading target signals to the radar operator. Electronic jamming works by transmitting additional radio signals towards enemy receivers, making it difficult to detect real target signals, or take advantage of known behaviors of automated systems like radar lock-on to confuse the system. Various counter-countermeasures can sometimes he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
