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].
