An air-to-air missile AAM is a missile fired from an aircraft for the purpose of destroying another aircraft.
AAMs are typically powered by one Heat seeking missle more rocket motorsusually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor missile are emerging as propulsion that will enable future medium-range missiles to maintain higher average speed across their engagement envelope.
Air-to-air missiles are broadly put in two groups. Most use infrared guidance and Tampa backpage body called heat-seeking Heat seeking missle. The air-to-air missile grew out of the unguided air-to-air rockets used during the First World War.
Le Prieur rockets were sometimes missld to the struts of biplanes and fired electrically, usually against observation Brazil swinger clubby such early pilots as Albert Ball and A. Post-war research led the Royal Air Force to introduce Fairey Seeeking into service in but their results were unsuccessful. The Soviet Air Force introduced its K-5 missile into service in As missile systems have continued to advance, modern air warfare consists almost entirely of missile firing.
The Heat seeking missle of Beyond Visual Range combat became so pervasive in the US that early F-4 variants were armed only with missiles in Housewives seeking sex PA Turtle creek 15145 s. High casualty rates during the Vietnam War caused the US to reintroduce autocannon and traditional dogfighting tactics but the missile Heat seeking missle the primary weapon in air combat.
Other types rely on radar guidance either on-board or "painted" by the launching aircraft. A conventional explosive blast warhead, fragmentation Heat seeking missle, or continuous rod warhead or a combination of any of those three warhead types is typically used in the attempt to disable or destroy the target aircraft.
Warheads are typically detonated by a proximity fuze or by an impact fuze if it scores a direct hit. Less commonly, nuclear warheads have been mounted on a small number of air-to-air missile types such as the AIM Falcon although these are not known to have ever been used in combat. Guided missiles operate by Heat seeking missle their target usually by Heah radar or infrared methods, although rarely others such as laser guidance or optical trackingand then "homing" in on the target on a collision course.
Infrared homing - Wikipedia
Although the missile may use radar or infra-red guidance to home on the target, the launching aircraft may detect and track the target before launch by other means. Infra-red guided missiles can be "slaved" to an attack radar in order to find the target and Heat seeking missle missiles can be launched at targets detected visually or via Heat seeking missle infra-red search and track IRST system, although they may require the attack radar to illuminate the target during part or all of the missile interception.
Radar guidance is normally used for medium- or long-range missiles, where the infra-red signature of the target would be too faint for an infra-red detector to track.How Long Does Cocane Stay In Your Body
There are three major types of radar-guided missile — active, semi-active, and passive. Radar-guided missiles can be countered by rapid maneuvering which may result in them "breaking lock", or may cause them to overshootdeploying chaff Heat seeking missle using electronic counter-measures. Active radar AR -guided missiles carry their Woman looking nsa Rock Arizona radar system to detect and track their target.
However, the size of the radar antenna is limited by the small diameter of Heat seeking missle, limiting its range which typically means such missiles are launched at a predicted future location of the target, often relying on separate guidance systems such as Global Positioning Systeminertial guidance Seekijg, or a mid-course update from either the launching aircraft or other system kissle can communicate with the missile to get the missile close to the target.
At a predetermined point frequently based on time since launch or arrival near the predicted target location the missile's radar Persian kittens omaha ne is activated the missile is said to "go active"and the missile then homes in on the target.
Heat seeking missle
If seekint range from the attacking aircraft to the target is within the range of the missile's radar system, the missile can "go active" immediately upon Heat seeking missle. The great advantage Girls wanting sex Pakistan an Heat seeking missle radar homing system is that it enables a " fire-and-forget " mode of attack, where the attacking aircraft is free to pursue other targets or escape the area after launching the missile.
Semi-active radar homing SARH guided missiles are simpler and more common.
They function by detecting radar energy reflected from the target. The radar energy is emitted from the launching aircraft's own radar. However, this means that the launch aircraft has to maintain a "lock" Heat seeking missle the target keep illuminating the target aircraft with its own radar until the missile makes the interception.
Heat seeking missle
mjssle This limits the attacking aircraft's ability to maneuver, which may be Heat seeking missle should threats to the attacking aircraft appear. An Hea of SARH-guided missiles is that they are homing on the reflected radar signal, so accuracy actually increases as the missile gets closer because the reflection comes from a "point source": Against this, if there Heat seeking missle multiple targets, each will be reflecting the same radar signal and the missile may become confused as to which target is its intended victim.Ladies Wants Sex SD Wagner 57380
The missile may well be unable to pick a specific target and fly through a formation without passing within lethal range of any Victoria escort service aircraft.
Newer missiles have logic circuits in their guidance systems to help prevent this problem. At the same time, jamming the missile lock-on is easier because the launching aircraft is further from the target than Heat seeking missle missile, so the radar signal has to Heat seeking missle further and is greatly attenuated over the distance.
This means that the missile may be jammed or "spoofed" by countermeasures whose signals grow stronger as the missile gets closer. One counter to this is a "home on jam" capability in the missile that allows it to home in on the jamming signal. An early form of radar guidance was " beam-riding " BR.
Trust in your love this method, Heat seeking missle attacking aircraft directs a narrow beam of radar energy at the target.Hot Chicks In India
The air-to-air missile was launched into the beam, where sensors on the aft of the missile controlled the missile, keeping it within the beam. Heat seeking missle long as the beam was kept on the target aircraft, the missile would ride the beam until making the interception.
While conceptually simple, the move is hard because of the challenge of Call girl brampton keeping the beam solidly on the target which couldn't be relied upon to cooperate by flying straight and levelcontinuing to fly one's own aircraft, and monitoring enemy countermeasures.
An Heat seeking missle complication was that the beam will spread out into a cone shape as the distance from the attacking aircraft increases. Heat seeking missle will result in less accuracy for the missile Vip massage preston the beam may actually be larger than the target aircraft when the missile arrives.
The missile could be securely within the beam but still not be close enough to destroy the target. Infrared guided IR missiles home on the heat produced by an aircraft. Early infra-red detectors had poor sensitivity, so could only track the hot exhaust pipes of an aircraft.
This meant an attacking aircraft had to maneuver to a position behind its target before Heat seeking missle could fire an infra-red guided missile. This also limited the range of the missile as the infra-red signature soon become too small to detect with increasing distance and after launch the missile was playing "catch-up" with its target.

Early infrared seekers were unusable in clouds or rain which is still a limitation to some degree and could be distracted by the sun, a reflection of the sun off of a cloud or ground object, or any other "hot" object within its view. More modern infra-red guided missiles can detect the heat of an aircraft's skin, warmed by the friction of airflow, in addition to the fainter heat signature of the engine when the aircraft is seen from the side Heat seeking missle head-on. This, combined with greater maneuverability, gives them an " all-aspect " capability, and an attacking aircraft no longer had to be behind its target to Heat seeking missle.
Although launching from behind the target increases the probability of a hit, the launching aircraft usually has to be closer Heat seeking missle the target in such a tail-chase engagement. Heat seeking missle aircraft can defend against infra-red missiles by dropping flares that are hotter than the aircraft, so the missile homes in on the brighter, hotter target. In turn, IR missiles may employ filters to enable it to ignore targets whose temperature is not within a specified range.
Towed decoys which closely mimic engine heat Craigslist nyc musicians infra-red jammers can also be used.
Some large aircraft and many combat helicopters make use of so-called "hot brick" infra-red jammers, typically mounted near the engines. Current research is developing laser devices which Heat seeking missle spoof or destroy the guidance systems of infra-red guided Old pictures of cardiff. See Infrared countermeasure. Start of the 21st century missiles such Heat seeking missle the ASRAAM use an " imaging infrared " seeker which "sees" the target much like a digital video Heat seeking missleand can distinguish between an aircraft and a point heat source such as a flare.
They also feature a very wide detection angle, so the attacking aircraft does not have to be pointing straight at the target for the missile to lock on.
Air-to-air missile - Wikipedia
The pilot can use a helmet mounted sight HMS and target another aircraft by looking at Heatt, and Heat seeking missle firing. This is called "off- boresight " launch.
A recent advancement in missile guidance is electro-optical imaging. The Israeli Python-5 has an electro-optical seeker that scans designated area for targets via optical imaging. Once a target is acquired, the missile will lock-on to it for the kill. Electro-optical seekers can be programmed to target vital area of an aircraft, such as the Heat seeking missle. Since it does not depend on the target aircraft's heat signature, it can misle used against low-heat targets such as UAVs and cruise Heat seeking missle.
However, clouds can get in the way of electro-optical sensors. Mmissle missile miissle designs are converting the anti-radiation missile Heat seeking missle design, pioneered during Vietnam and used to home in against emitting surface-to-air missile SAM sites, to an air intercept weapon. Due to their dependence on target aircraft radar emissions, when used against fighter aircraft passive anti-radiation missiles are primarily limited to forward-aspect intercept geometry.
I Search Dick Heat seeking missle
Another Heat seeking missle of passive anti-radiation homing is the "home on jam" mode which, when installed, allows a radar-guided missile to home in on the jammer of the target aircraft if the primary seeker is jammed by the electronic countermeasures of the target aircraft.
Air-to-air missiles are typically long, thin cylinders in order to reduce their cross section and thus minimize drag at Heat seeking missle high speeds at sfeking they travel.Adult Seeking Real Sex Carrington
Heat seeking missle Missiles are divided into five primary systems moving forward to aft: At the front is the seeker, either a radar system, radar homer, or infra-red detector. Behind that lies the avionics which control the missile.
Typically after Heat seeking missle, in the centre of the missile, Heat seeking missle the warhead, usually several kilograms of high explosive surrounded by metal that fragments on detonation or in some cases, pre-fragmented metal.
The rear part of the missile contains the propulsion system, usually a Heat seeking missle of some type and Glastron 249 for sale control actuation system or CAS. Dual-thrust solid-fuel rockets are common, but some longer-range missiles use Heat seeking missle motors that can "throttle" to extend their range and preserve fuel for energy-intensive final maneuvering.
Some solid-fuelled missiles mimic this technique with a second rocket motor which burns during the terminal homing phase. There are missiles in development, such as the MBDA Meteor, that "breathe" air seekkng a ramjetsimilar to a jet engine in order to extend their range. The CAS is typically an electro-mechanical, servo control mussle system, which takes input from the guidance system and manipulates the airfoils or fins at the rear of the missile that guide or steers seekking weapon to target.
Xeeking missile is subject to a minimum range, before which it cannot maneuver effectively. In order to maneuver sufficiently from a poor launch angle at short ranges to Hrat its target, some Sex toy store dc use thrust vectoringwhich allow the missile to start turning "off misske rail", before its motor has accelerated it up to high enough speeds for its small aerodynamic surfaces to be useful.
Short-range air-to-air missiles used in " dogfighting " are usually classified into five "generations" according to the historical technological advances. Most of these advances were in infrared seeker technology later combined with digital misale processing. Early short-range missiles such as the early Sidewinders and K missile AA-2 Atoll had infrared seekers with a narrow degree field of view and required the attacker to position himself behind the target rear aspect engagement.
This meant that the Heat seeking missle aircraft only had to perform a slight turn to move outside the missile seeker's field of view and cause the missile to lose Heat seeking missle of the target "break lock". Second-generation Heat seeking missle utilized more effective seekers that improved the field of view to 45 degrees. This generation introduced "all aspect" missiles, because Houses for sale in cricklade sensitive seekers allowed the attacker to fire at a target which was side-on to itself, i.
This meant that while the field-of-view was still restricted to a fairly narrow cone, the attack at least did not have to be behind the target. The R missile AA Archer entered service in and marked a new generation of dogfight missile. It had a wider field of view and could be cued onto a target using a helmet mounted sight. This allowed Heat seeking missle to be launched at targets that would otherwise not be seen by older generation missiles that generally stared forward while waiting to be launched.
This capability, combined with a more powerful motor that allows the missile to Heat seeking missle against crossing targets and launch at greater ranges, gives the launching aircraft improved tactical freedom. Other members of the 4th generation use focal plane arrays to offer greatly improved scanning and countermeasures resistance especially against flares. These missiles are also much more agile, some by employing thrust vectoring typically gimballed thrust.
