The aerodynamic stand for research of ice-forming characteristics of reagents

Abstract

The installation developed for operative research of efficiency of ice-forming pyrotechnical compositions used for suppression of hailfall is presented. In the work, we describe the variant based on a small aerodynamic stand which makes it possible to control efficiency of ice-formation of full-size generators in the on-line mode and to study nucleation activity of new reagents in dynamic conditions. Elements of the developed technology for research of the pyrotechnic compositions used in practice of active influences of hail-suppression services are described. Experimental data for one of the pyrotechnic compositions based on silver iodide (AgI) are presented.
