This report includes results of several ongoing efforts a Modifications were made in the computer codes for 2-D diffusion flames to reduce the computation times. A reduction by about 50 was achieved. b A survey of the literature on combustion of AP-HC sandwiches was made. c A study of catalysis of burning rate of sandwiches with Fe203 in the binder lamina was extended to the case where fine AP was added to the binder lamina. The results showed that catalysis of reactions in the region of the burning surface are important contrary to earlier results with catalysts plus binder alone. d Studies of melting and decomposition were run on several oxidizers, binders, and combinations using a hot-stage microscope results are included. e Preliminary studies were made of mechanisms that cause plateau burning in AP-HC binder propellants. Results indicate that binder melt flow over the AP surfaces is a major factor confirming past speculation. f Revisions were made in the laboratory facilities to permit testing at higher pressures and with more hazardous materials.
