Characterisation of novel formulations designed for hail suppression and rain enhancement technologies

Abstract. This paper presents some new polymer bonded pyrotechnical compositions designed for hail suppression and rain enhancement. The chemical composition of the formulations is optimized based on the silver iodide thermal stability and two perchlorate type of oxidizers are evaluated for perspective use. The main combustion parameters combustion temperature and burn rate are presented in conjunction with the resulting aerosols, investigated trough SEM-EDS. The chemical stability of the novel formulations are evaluated by VST studies. The research highlight the potential use of the presented formulations in the fabrication of drone/aviation delivered pyro cartridges aerosol generators.
