Abstract:
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.
Keywords:
