MM2 LRSLA Testing Stage III Propellant.

Abstract

Data in this report is a continuation of LRSLA testing on Stage III Dissected Motors. Problems in testing C-7 bonds were not alleviated by changing specimen size as previously suggested. The data variation that has been observed has prompted a closer analysis of testing for variance. The plotted points used on the regression plots are a combined average of test results at a designated test period. The data variance within test periods is now demonstrated with the addition of separating the test results into individual plotted points on the regressions for each test period. Data variance between motors is demonstrated by the use of unique motor plot symbols in the multi-motor regressions. These unique symbols are data mean values and the number of samples per mean can be found with its minimum and maximum values in the sample size summary. Additional keywords: Solid propellant rocket engines, Linear regression analysis, Stress relaxation, Hardness, Fracture toughness, Tensile testers, MINUTEMAN. (Author)
