Abstract

This paper describes the experimental setup for estimation of pyrotechnic smoke composition for anti-infrared roles using thermal imager operating in the wavelengtt range of 8-12 l . Several pyrotechnic compositions based on thoroughly mixes maleic acid, potassium chlorate, calcium silicide, calcium carbonate, sodiurr carbonate, naphthalene, anthracene, ammonium chloride and commercial boiled of have been tested. Hot plate of temperature ranging between 101 °C and 120 °C way used to represent the source of emitted infrared radiation. The temperature of the ho source was traced during the generation of the pyrotechnic smoke inside a specially designed smoke testing laboratory tunnel. The effect of both the pyrotechnic composition and the amount of each sample on the attenuation of the hot source temperature was shown and discussed. The experimental work was done in ar ambient temperature of 38 °C during June month in the afternoon period.
