Abstract:

A study of the detonation performance of the insensitive explosive filling, PBXW-115 Aust., has been undertaken and the results compared to those from its American counterpart, PBXW-115 USAPBXN-111, an explosive of the same nominal composition but formulated with bimodal RDX of different type and somewhat differing particle size distribution. The limiting value of the velocity of detonation at infinite diameter, D, of PBXW-115 Aust. is in the range 5.64 to 5.91 kms, the actual value depending on the assumed relationship between the experimental V of D and the diameter of the charge. This range of values is slightly less than that calculated for PBXW-115 USA, 5.76 - 6.19 kms, using experimental data reported by Forbes et al. 1989. MM
