Claims25
A composition comprising boron at from about 1 wt % to about 17.5 wt %, potassium ferricyanide at from about 1 wt % to about 8 wt %, potassium perchlorate at from about 30 wt % to about 60 wt %, an energetic binder, and one of dibutyltin dilaurate, triphenylbismuth, magnesium carbonate, or dibutyltin diacetate.
A countermeasure device comprising a casing and a flare composition contained in the casing, the flare composition comprising boron at from about 1 wt % to about 17.5 wt %, potassium ferricyanide at from about 1 wt % to about 8 wt %, potassium perchlorate at from about 30 wt % to about 60 wt %, an energetic binder, and one of dibutyltin dilaurate, triphenylbismuth, magnesium carbonate, or dibutyltin diacetate.
A method of using a countermeasure device, comprising:
- deploying a countermeasure device against a heat-seeking device, the countermeasure device
- comprising a casing and a flare composition contained in the casing, the flare
