PROJECT SOPHY. SOLID PROPELLANT HAZARDS PROGRAM

Abstract

A correlation is reported that evaluates the use by the detonation model of the modified Jones model, to describe nonideal detonation characteristics of solid-composite propellant. An analysis of the perturbation of the detonation process in hollow cylindrical charges is presented. The critical geometries of triangular and rectangular columns have been found to be 95 and 94% of the critical diameter, respectively. The pseudocritical geometries (defined in this report) for circular-core and cross-core hollow cylinders both are 88% of the critical diameter. The Hugoniot of AAB-3225 propellant (adulterated propellant containing 7.1% RDX) is reported. A generalized expression for the effectice grain radius has been developed. Corrected values of the peak overpressure data from the two large critical-diameter tests of unadulterated propellant (72-in. diameter and 60-in. diameter) are reported. Progress has been made in determining the effect of several processing parameters on the quality of cast porous propellant. Techniques to measure the surface area of cracked propellant samples are being evaluated.
