Heat seekers on missiles are now able to react to the heat signatures of jet aircraft engines in various run modes.
Hey guys! We’d like to unveil details of the recent improvement in the mechanics of acquiring the thermal signatures of jet engines by missile seekers. The fact is that the picture of the intensity and distribution of heat from an aircraft jet engine directly depends on its operational mode. So, in non-afterburning modes, the intensity of the plumes of hot gasses in the forward hemisphere of an aircraft is low and comparable to the intensity of the glow of a heated fuselage skin. At the same time, the expanding flame of burning fuel in afterburner modes has a significant luminosity not only in the rear, but also in the front hemispheres of the aircraft.
The lock-on range of infrared homing heads in the forwa...
