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 (USA)/PBXN-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 km/s, 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 km/s, using experimental data reported by Forbes et al. (1989). (MM)
