Abstract:
The detonation characteristics of an aluminized EMX with a density of $\approx$ 0.5 g/cm$^3$ and with a mass content of aluminum up to 20% were determined. The addition of aluminum leads to an increase in detonation velocity and detonation pressure in comparison with the parameters of the pure EMX. Replacing aluminum with ground glass leads to a decrease in both detonation velocity and pressure. The increased detonation characteristics of the aluminized EMX can be due to the partial reaction of aluminum before the Chapman-Jouguet plane. The brightness temperature of detonation products of the aluminized EMX was measured. It is shown that it decreases with the addition of aluminum to the EMX. This result demonstrates the complex effect of aluminum addition on the detonation characteristics of the EMX.
