How effective are flares against heat seeking missiles?

Flares are one effective and simple way to deflect heat-seeking missiles, but military fleets rely far more on infrared jamming systems. Safer over populated areas than burning flares and perhaps a bit more effective, jamming devices deflect manpads by exploiting the way that the missiles track their targets.

How hot are flare countermeasures?

Those pellets are so hot — more than 2,000 degrees Fahrenheit — that the temperature exceeds that of the aircraft’s engine or exhaust, tricking an infrared-guided missile about the path of the aircraft.

Do flares work against modern missiles?

Traditional flares—burning pyrotechnics that are dropped from aircraft to fool incoming missiles—will not be effective against the latest missile infrared guidance technology, he said.

How hot are aircraft flares?

2,000 degrees Fahrenheit
Self-protection flares are magnesium pellets that, when ignited, burn for a short period of time (less than 10 seconds) at 2,000 degrees Fahrenheit. The burn temperature is hotter than the exhaust of an aircraft and therefore attracts and decoys heat-seeking weapons targeted on the aircraft.

Why do fighter jets use flares?

A flare or decoy flare is an aerial infrared countermeasure used by a plane or helicopter to counter an infrared homing (“heat-seeking”) surface-to-air missile or air-to-air missile. The aim is to make the infrared-guided missile seek out the heat signature from the flare rather than the aircraft’s engines.

Do flares work against amraams?

Basically – flares are very effective against older SAM/AAM models like Strela or Red Eye, not so against dual IR/UV or high-def IR homing heads.

Do flares stop homing missiles?

These decoy flares, which are also called pyrophoric flares, because they burn up the moment they ‘touch’ the air, work to prevent a heat-seeking missile from hitting its (intended) target in a rather brilliant way. The missile that has been fired is ‘heat-seeking’, i.e., it works on the principle of infrared homing.

How does a heat-seeking missile work?

Its a passive weapon systen which uses infrared emissions from a target to follow it. Infrared emissions are released and radiated strongly by Hot Bodies such as the engine of the jet. These missiles when fired track the heat signature and follow it.

What type of warhead does the amraam AAM have?

AIM-120 AMRAAM
Warhead	High explosive blast-fragmentation • AIM-120A/B: WDU-33/B, 50 pounds (22.7 kg) • AIM-120C-5: WDU-41/B, 40 pounds (18.1 kg)
Detonation mechanism	Active RADAR Target Detection Device (TDD) Quadrant Target Detection Device (QTDD) in AIM-120C-6 – lots 13+.
Engine	Solid-fuel rocket motor

How many Gs can an amraam pull?

For example the AMRAAM can pull 30 Gs max and probably turns tightest at Mach 3 speed. The AIM-9X Sidewinder can pull 60 Gs etc.

The missile that has been fired is ‘heat-seeking’, i.e., it works on the principle of infrared homing. Essentially, the missile is programmed to ‘seek’ the heat released from the exhaust of your fighter jet. You’d be doomed, if not for the decoy flares that your aircraft has onboard.

How effective are MTV flares against missiles?

The MTV flares are quite effective against older type missiles that seek heat in a single IR band. Many attempts have been made in the past two decades to increase the intensity of IR decoys and to modify the spectral distribution of the radiation they emit. These attempts have not met with significant success.

Why do missiles flare up when they burn up?

The burning MTV emits IR radiation that is essentially a spectral continuum attenuated by atmospheric absorption. It is intended that the falling flare will cause a missile seeker head to turn away from the target aircraft.

What is the difference between a jet engine and an IR missile?

Flares burn at thousands of degrees Celsius, which is much hotter than the exhaust of a jet engine. IR missiles seek out the hotter flame, believing it to be an aircraft in afterburner or the beginning of the engine’s exhaust source.
