Dielectric relaxation in energy condensed systems on the basis of a polyesterrethane elastomer. II. Temperature dependence and ignition

This paper describes the effect of the composition of energy condensed systems, containing glycerol trinitrate, aluminum powder, ammonium perchlorate, and HMX, on their ignition in an electric field with a frequency of 50 Hz. Conditions under which energy condensed systems ignite in an alternating electric field with a frequency of 50 Hz are determined experimentally. Temperature changes of their dielectric characteristics in a frequency range from 20 Hz to 1 MHz are established. The possibilities of an electric breakdown and heating of the samples are theoretically estimated. It is revealed that electrical luminescence is observed in a polymer binder based on glycerol trinitrate and polyetherurethane.
