Solid Propellent Burning Rate Theory: Recently Advanced Theories, Their Limitations and Possible Areas for Future Investigation

The progress of solid propellent technology appears to have been retarded by lack of development of a fundamental mechanism of burning. A study of previous work indicates that while experimental techniques used are valid, hypotheses were inadequate; and fresh hypothetical approaches are needed. There is evidence of lack of theory development in the more fundamental field of the combustion of turbulent, pre‐mixed, fuel‐rich flames as it applies to propellent burning. The roles of radiative heat transfer and a physical disintegrative mode of surface dissipation are proposed for consideration. Previous experimental techniques together with new ones are proposed to exploit these hypotheses.
