Abstract

Several aspects of pyrotechnic devices used to produce smoke, flash and sound are discussed quantitatively. The main aim of this paper is to demonstrate economical techniques to tailor pyrotechnic formulations to meet specific needs. It is seen that the cloud size is independent of the charge weight in the range of 2-80 gm, a theoretical result that is verified by experimental data. The noise is found to bein good agreement with experimental data, especially after allowance is made for absorption in the atmosphere. Several formulations are tested and the results are presented.

Tailoring of pyrotechnics to achieve specific effects of cloud size, shape and longevity is discussed. Applications of pyrotechnics for gas generation purposes are also mentioned. It is seen that these studies complement more extensive testing; mutually, they introduce great economy and provide insight not possible with empirical approaches.
