Abstract:
This paper presents a new look at the structure of the radiance signal recorded by an optical pyrometer in measuring the brightness temperature of the detonation front of an emulsion explosive with glass microballoons as a sensitizer. The structure of the optical signal is typical of heterogeneous explosives: first a short temperature spike of up to 2500–3400 K occurs related to the formation of a layer of hot spots igniting the matrix capable of releasing energy, after which the radiance decreases to the quasi-equilibrium level corresponding to a temperature of 1880–2370 K at a detonation pressure of 0.7–11 GPa. There is satisfactory agreement between the experimental data and the results of independent calculations.
Keywords:
