|発明の名称||LIGHT EMISSION DEVICE HAVING HIGH INFRARED RAY RADIATING FUNCTION|
PROBLEM TO BE SOLVED: To improve the radiation of infrared ray of the plume produced from an exhaust device of an infrared ray emitting device releasing the infrared ray when the infrared ray induction flying object comes, so that the radiation of infrared ray is increased when it is observed from a rear part of the exhaust device, and the deceptive effect is increased.
SOLUTION: In this infrared ray emitting device for protecting an aircraft from the flying object by the induction of infrared ray, a member having an air inlet hole 3 is mounted on the exhaust device, whereby the secondary combustion effect of the released infrared ray radiative product can be increased, and a combustion temperature is raised, and further the high infrared ray is radiated by enlarging a diameter of the plume. As a straightening device for controlling the shape of the plume is mounted on a rear part of an injection hole of the exhaust device, the shape of the plume produced by releasing the infrared ray radiative product can be arbitrarily changed, whereby the infrared ray radiating characteristic same as the plume of the aircraft can be obtained.
