    • This invention proposes to make use of an already developed set of hardware which dispenses and controls the performance of towed decoys capable of defeating radar guided weapons. Using this same hardware, a new and unique payload, payload control and dispensing mechanism is inserted into a decoy towbody. The payload consists of foils and/or foil packs of a pyrophoric material. This material creates an infrared (IR) signature behind the decoy that is more attractive than the infrared plume emitted by the aircraft engine. The fact that the IR decoy is towed insures that it will be kinematically correct by flying the same profile as the aircraft so as to remain within the field of view of the missile's seeker. Because the pyrophoric material can be metered (dispensed at varying and controllable rates) its radiant intensity can be matched with that of the engine of the towing aircraft. As the burn characteristics of the selected pyrophoric material match the burn profile of hydrocarbon based jet fuels, the towed IR decoy also emits a plume that spectrally matches that of its host aircraft's engine.
    • 本发明提出利用已经开发的一套硬件,可以分配和控制能够击败雷达制导武器的拖曳诱饵的性能。 使用这个相同的硬件,一个新的和唯一的有效载荷,有效载荷控制和分配机构被插入诱饵拖船。 有效载荷由自燃材料的箔和/或箔包组成。 这种材料在诱饵后面产生比由飞机发动机发射的红外线羽毛更有吸引力的红外(IR)签名。 IR诱饵被拖曳的事实确保通过与飞机相同的轮廓飞行而使其运动学正确,以便保持在导弹的寻求者的视野之内。 因为自燃材料可以计量(以不同的和可控的速率分配),所以其辐射强度可以与牵引飞机发动机的辐射强度相匹配。 由于所选择的自燃材料的燃烧特性与基于烃的喷气燃料的燃烧曲线相匹配,拖曳的红外诱饵也会发出与其主机飞机的发动机光谱匹配的羽流。
