Abstract : Four different lots of LOVA propellants were analyzed to determine quantitatively the distributive mixing achieved by two continuous and two batch mixing processes. The degree of mixing distribution technique based on wide-angle x-ray diffractometry, which was developed with earlier funding of U.S. Army Production Base Modernization Activity, was successfully applied to assess and compare the four LOVA lots and the four processing methodologies applied. The quantitative degree-of-mixing parameters obtained through this work were also found to be amenable for prediction the propellant performance, i.e., the LOVA lot that failed the burn test in the field exhibited the lowest degree of mixing, whereas the LOVA lot that passed the burn test exhibited one of the highest degree of mixing in this investigation. The new technique has also been applied successfully in evaluation of other multi-component energetics and its potential for applicability as an on-line and on-site technique is suggested.
