Abstract:

It is of definite importance to measure the velocity of detonation of condensed explosives with a charge having a low density, where the products of the explosion are not governed by the equation of the state of ideal gases, but the elastic component of the pressure is small compared to the total pressure. To this zone correspond pressures resulting from a detonation of explosives whose density is less than 0.8 gramscubic centimeter. In the majority of cases, however, the lower value of the density at which the detonation velocity of explosives is determined amounts to 0.5-0.6 gramscubic centimeter. It is a fact that it is difficult to determine the detonation velocity of the majority of explosives at lower densities. In this work, the relationship between the detonation velocity and the density of explosives was investigated by using nitrocellulose 13.3 N2 which can provide charges of low density. Because the detonation velocity of nitrocellulose was not measured before, tests included a wide range of densities of the charge.
