Abstract
An illuminating non-metallic pyrotechnic composition is disclosed which consists essentially of, expressed in absolute weight units: (a) from about 51 to 61 parts of strontium nitrate, (b) from about 15 to 25 parts of potassium perchlorate, (c) from about 15 to 25 parts of sulfur, (d) about 3 parts of sodium nitrate, and (e) about 2 parts of uintaite. Optimum flare luminosity is achieved when the composition is essentially free of other fuel constituents, such as dextrin, nitrocellulose charcoal. A flare is disclosed comprising the disclosed pyrotechnic composition.
