Nag (ATGM)
The Nag missile (IAST: ''Nāga''; en: Cobra), also called "Prospina" for the land-attack version, is an Indian third-generation, all-weather, fire-and-forget, lock-on after launch, anti-tank guided missile (ATGM) with an operational range of 500m to 20km depending on variant. It has a single-shot hit probability of 90% and a ten-year, maintenance-free shelf life. The Nag has five variants under development: a land version, for a mast-mounted system; the helicopter-launched Nag (HELINA) also known as Dhruvastra; a "man-portable" version (MPATGM); an air-launched version which will replace the current imaging infra-red (IIR) to millimetric-wave (mmW) active radar homing seeker; and the Nag Missile Carrier (NAMICA) "tank buster", which is a modified BMP-2 infantry fighting vehicle (IFV) produced under license in India by Ordnance Factory Medak (OFMK). Development of the Nag is part of the Integrated Guided Missile Development Program (IGMDP), run by Defence Research and Developme ...

Anti-tank Guided Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave lig ...

Extremely High Frequency
Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ten to one millimetre, so it is also called the millimetre band and radiation in this band is called millimetre waves, sometimes abbreviated MMW or mmWave. Millimetre-length electromagnetic waves were first investigated by Indian physicist Jagadish Chandra Bose, who generated waves of frequency up to 60GHz during experiments in 18941896. Compared to lower bands, radio waves in this band have high atmospheric attenuation: they are absorbed by the gases in the atmosphere. Absorption increases with frequency until at the top end of the band the waves are attenuated to zero within a few meters. Absorption by humidity in the atmosp ...

Imaging Infrared
Infrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become ea ...

Lock-on After Launch
Lock-on after launch (LOAL) is an ability of missile systems to lock-on to a target after being launched from a carrier vehicle. The term is normally used in reference to airborne weapons, especially air-to-air missiles. LOAL is an important part of modern weapon systems as it allows a weapon to be carried internally to increase stealth and then acquire a target once it has left a launching aircraft. LOAL systems normally rely on cuing from a helmet mounted sight or onboard sensors like radar or forward-looking infrared (FLIR), and use a simple strapdown inertial guidance system to know where to look after launch. Examples of LOAL weapons include the Advanced Short Range Air-to-Air Missile (ASRAAM) and later versions of the AGM-114 Hellfire anti-tank missile An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a Missile guidance, guided missile primarily designed to hit and destroy Armoured fighting vehicle, hea ...

Fire-and-forget
Fire-and-forget is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, a laser designator) is vulnerable to attack and unable to carry out other tasks. Generally, information about the target is programmed into the missile just prior to launch. This can include coordinates, radar measurements (including velocity), or an infrared image of the target. After it is fired, the missile guides itself by some combination of gyroscopes and accelerometers, GPS, onboard active radar homing, and infrared homing optics. Some systems offer the option of either continued input from the launch platform or fire-and-forget. Fire-and-forget missiles can be vulnerable ...

Nāga
The Nagas (IAST: ''nāga''; Devanāgarī: नाग) are a divine, or semi-divine, race of half-human, half-serpent beings that reside in the netherworld (Patala), and can occasionally take human or part-human form, or are so depicted in art. A female naga is called a Nagi, or a Nagini. According to legend, they are the children of the sage Kashyapa and Kadru. Rituals devoted to these supernatural beings have been taking place throughout South Asia for at least 2,000 years. They are principally depicted in three forms: as entirely human with snakes on the heads and necks, as common serpents, or as half-human, half-snake beings in Hinduism, Buddhism, and Jainism. ''Nagaraja'' is the title given to the king of the nagas. Narratives of these beings hold cultural significance in the mythological traditions of many South Asian and Southeast Asian cultures, and within Hinduism and Buddhism, they are the ancestral origins of the Nagavanshi Kshatriyas.

International Alphabet Of Sanskrit Transliteration
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Brahmic family, Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the nineteenth century from suggestions by Sir Charles Trevelyan, 1st Baronet, Charles Trevelyan, William Jones (philologist), William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva International Congress of Orientalists, Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars. Usage Scholars commonly use IAST in publications that cite textual material in Sanskrit, Pāḷi and other classical Indian languages. IAST is also used for major e-te ...

Mil Mi-24
The Mil Mi-24 (russian: Миль Ми-24; NATO reporting name: Hind) is a large helicopter gunship, attack helicopter and low-capacity troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with 48 other nations. In NATO circles, the export versions, Mi-25 and Mi-35, are denoted with a letter suffix as "Hind D" and "Hind E". Soviet pilots called the Mi-24 the "flying tank" (russian: летающий танк, letayushchiy tank, links=no), a term used historically with the famous World War II Soviet Il-2 ''Shturmovik'' armored ground attack aircraft. More common unofficial nicknames were "Galina" (or "Galya"), "Crocodile" (russian: Крокодил, Krokodil, links=no), due to the helicopter's camouflage scheme, and "Drinking Glass" (russian: Стакан, Stakan, links=no), because of the flat glass plates that surround earlier Mi-24 variants' cockpits. ...

HAL Prachand
The HAL Prachand (IPA: prəcəɳɖ, lit.''"Fierce"'') is an Indian multi-role, light attack helicopter designed and manufactured by the Hindustan Aeronautics Limited (HAL) under project LCH. It has been ordered by the Indian Air Force and the Indian Army. Its flight ceiling is the highest among all attack helicopters in the world. The true impetus for the development of the LCH Prachand came in the form of the Kargil War, a conflict fought between India and neighbouring Pakistan in 1999, which revealed the Indian armed forces lacked a suitable armed rotorcraft capable of operating unrestricted in the high-altitude theatre. Accordingly, both HAL and the Indian armed forces commenced exploratory efforts towards the conceptualisation of a combat helicopter to perform in this role. During 2006, the company announced that it had launched a development programme to produce such a rotorcraft, referred to simply as the LCH or Light Combat Helicopter. Originally, the LCH was anticipate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HAL Rudra
The HAL Rudra, also known as ALH-WSI, is an armed version of the HAL Dhruv utility helicopter which is designed and produced by the Indian aerospace manufacturer Hindustan Aeronautics Limited (HAL). The Rudra was developed in parallel to the HAL Light Combat Helicopter (LCH), a more extensive attack helicopter developed from the Dhruv. Extensive changes from the Dhruv were avoided to produce the Rudra with the express purpose of providing an indigenous armed helicopter faster than the LCH programme could do so. The Mark III variant features the sensors and mission equipment, but lacked weaponry; the Rudra Mark IV is provisioned with various armaments. The Rudra is equipped with forward looking infrared (FLIR), day-and-night optical cameras, and a Thermal Imaging Sights Interface; armed models feature a 20 mm turret gun, 70 mm rocket pods, anti-tank guided missiles and air-to-air missiles. Work on the programme started in December 1998, and the prototype Rudra conducted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
