Pyrotechnic Countermeasures: V. Performance of Spectral Flare Compositions Based on Aromatic Compounds

Abstract: The radiometric performance and burn rate of four spectral flare compositions (R-X) based on 1,4-dicyanobenzene (1), 3,5-dinitrobenzonitrile (2), E-stilbene (3) and 9,10-dihydroanthracene (4), potassium perchlorate and polyacrylate binder are described. The burn rates, spectral efficiencies, Eλ, in both α- and β-band have been determined. The composition R-4 displays the highest efficiency in both α- and β-band as well as lowest color ratio, θB/A. R-1 yields the highest color ratio and second highest spectral efficiency in β-band. For part IV see Ref. [1]
