A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust.
The doppler effect only occurs for the component of velocity parallel to the radar beam. To overcome this in use large amounts of chaff are deployed and then the aircraft will turn so that it moves predominantly perpendicular to the radar source. It may also rotate to minimize its cross section exposed to the radar beam.
The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile. Conventional man-portable air defense systems -launched missiles include an infrared sensor that is sensitive to heat, for example the heat emitted from an aircraft engine. The missile is ...
Newly-released footage by the Pentagon shows Chinese military planes flying close to US aircraft in what the US military has called “coercive and risky operational behaviour”. One of the ...
If an aircraft needed to loiter over a high risk area or was flying slowly (as helicopters do), it would require a large number of flares to decoy any missile fired at it. The IRCM provided constant protection against infra-red guided missiles. The ALQ-144 and ALQ-147 were first delivered to the US military in 1981. Currently there are over ...
A Russian fighter jet flew within a few meters of a U.S. drone over Syria and fired flares at it, striking the American aircraft and damaging it, the U.S. military said Tuesday, the latest in a ...
The AN/ALE-47 system can be integrated on a wide range of aircraft, including helicopters, cargo aircraft and fighters. It reached initial operating capability (IOC) in the U.S. Navy in 1998. [4] It has been integrated on 38 different types of aircraft, including the F-16, F/A-18, C-17, CH-47 and UH-60. As of 2008, over 3000 sets have been ...
The Philippine military chief condemned Saturday what he said was the provocative actions of two Chinese air force aircraft that executed a dangerous maneuver and dropped flares in the path of a ...
