Beyond-visual-range Missile
A beyond-visual-range missile (BVR missile) or beyond-visual-range air-to-air missile (BVRAAM) is an air-to-air missile that is capable of engaging at ranges around or beyond. This range has been achieved using dual pulse rocket motors or booster rocket motor and ramjet sustainer motor. Medium-range, long-range, and very-long-range air-to-air missiles fall under the category of beyond-visual-range missiles. Older BVR missiles generally used the semi-active radar homing, and modern BVR missiles use the active radar homing missile guidance, guidance. In addition to the range capability, the missile must also be capable of tracking its target at this range or of acquiring the target in flight. Systems in which a mid-course correction is transmitted to the missile have been used. History Early air-to-air missiles used semi-active radar homing guidance, that is the missile used the radiation produced by the launching aircraft to guide it to the target. The latest generation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity Fuze
A Proximity Fuse (also VT fuse or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuses are designed for elusive military targets such as aircraft and missiles, as well as ships at sea and ground forces. This sophisticated trigger mechanism may increase lethality by 5 to 10 times compared to the common contact fuse or timed fuse. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch, or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching the target or after passing it. At the start of the Bl ...

Mikoyan MiG-29K
The Mikoyan MiG-29K (; NATO reporting name: Fulcrum-D) is a Russian all-weather carrier-based multirole fighter aircraft developed by the Mikoyan Design Bureau. The MiG-29K was developed in the late 1980s from the MiG-29M. Mikoyan describes it as a 4+ generation aircraft. The production standard MiG-29Ks differ from prototypes in features such as a multi-function radar and several new cockpit displays, the integration of RVV-AE (also known as R-77) air-to-air missiles, along with missiles for anti-ship and anti-radar operations, and several ground/strike precision-guided weapons. In the early 1990s only two MiG-29K prototypes were built because the Russian Navy preferred the Su-27K (later re-designated Su-33). Mikoyan continued its MiG-29K development despite the lack of financing since 1992. The programme received a boost in the late 1990s with India's requirement for a ship-borne fighter following the purchase of a former Soviet aircraft carrier. India received its firs ...

Solid Fuel
Solid fuel refers to various forms of solid material that can be burnt to release energy, providing heat and light through the process of combustion. Solid fuels can be contrasted with liquid fuels and gaseous fuels. Common examples of solid fuels include wood, charcoal, peat, coal, hexamine fuel tablets, dry dung, wood pellets, corn, wheat, rice, rye, and other grains. Solid fuels are extensively used in rocketry as solid propellants. Solid fuels have been used throughout human history to create fire and solid fuel is still in widespread use throughout the world in the present day. Solid fuel from biomass is regarded as a renewable energy source which can contribute to climate change mitigation efforts. Solid fuel from fossil fuels (i.e. coal) is not a renewable energy. Types Biomass Biomass that is used for energy production can be processed into solid fuels but also into liquid or gaseous fuels. In comparison, the term biofuel is nowadays mainly (but not exclusively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Radar Homing
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a passive radar, receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox (code word), Fox Three. Advantages There are two major advantages to active radar homing: * As the missile is tracking the target it is going to be much closer to the target than the launching platform during the terminal phase, thus the missile's tracking can be much more accurate and better resistant to electronic countermeasures. Active radar homing missiles have some of the best kill probability, kill probabilities, along with missiles employing track-via-missile guidance. * Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, an ...

Datalink
A data link is a means of telecommunications link, connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex (telecommunications), Duplex communications, communications in both directions simultaneously.

Mid-course Update
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
