Research is reported on 1 high resolution photomicrographs of the propellant surface during burning and 2 thermocouple traverses of the flame zone. In the program of high resolution photomicrography, emphasis was divided between the design and construction of a suitable pressure vessel and a mathematical examination of the factors which limit the minimum size particle which can be resolved. The thermocouple traverse studies were concerned with selection of the best instrumentation for read-out of the temperature-time record from imbedded thermocouples. For purposes of instrumentation development, relatively coarse thermocouples 0.5 mil wire were used, so that the records obtained were only qualitative in nature and their reproduction in the report was not justified.
