This report contains test results from propellant and insulation materials obtained from three Minuteman Stage 2 dissected motors and their corresponding propellant cartons. Testing was performed in accordance with Service Engineering General Test Directive GTD -2 Dissect dated 28 June 1974 and Project M83258C. Statistical analysis includes data from both inner ANP 2864 and outer ANP 2862 propellant from the dissected motors and where available, associated propellant cartons. A computer program was utilized to test for common populations of individual dissected motors. Linear regression plots using unique symbols to identify the different relationships between motor and carton data were used to establish general trends. Where a change has taken place and where comparisons could be made, the majority of the regression trend lines are flatter. Therefore, the data are not exceeding the previous sigma limitations. In addition, as more specimens are tested, the trends become more realistic. Most of the test specimens were prepared and tested in the axial orientation, that is, parallel to the longitudinal axis of the motor from which specimens were obtained. Author
