Abstract
An infrared illuminant composition and flares produced therefrom having increased burn rate and increased infrared intensity while maintaining low visible light intensity. The composition comprises potassium nitrate, cesium nitrate, hexamine, boron, silicon, ferric oxide and a binder. A process to produce infrared illuminant flares prevents or substantially eliminates chunking out of burning pieces of the illuminant at pressing increments in the flares.
Claims26
An infrared illuminant flare which upon burning has a burn rate of from about 0.055 in./sec., an infrared intensity of about 1,060 watts/steradian and visible light intensity of less than about 3000 candlepower.
An infrared illuminant flare comprising a flare casing packed with an infrared illuminant composition in which the illuminant composition comprises:
- ______________________________________ Component Weight percent ______________________________________ Potassium nitrate about 50 to 70%, Cesium nitrate about 9 to 20%, Hexamine about 14 to 18%, Silicon about 5 to 10%, Boron about 1 to 3%, Ferric oxide about 1/2 to 11/2%, Binder about 4 to 8%. ______________________________________
An infrared illuminant composition comprising:
- ______________________________________ Component Weight percent ______________________________________ Potassium nitrate about 50 to 70%, Cesium nitrate about 9 to 20%, Hexamine about 14 to 18%, Silicon about 5 to 10%, Boron about 1 to 3%, Ferric oxide about 1/2 to 11/2%, Binder about 4 to 8%. ______________________________________
In a process for pressing an infrared illuminant composition into a flare case the improvement comprising employing a multi-stepped pressing foot for pressing the composition in the case.
