- Abstract
- An extensive series of experimental rocket motor test firings has been conducted in a systematic manner to determine the rate of pressure decrease which is required to just extinguish a burning solid propellant. The results of these experimental tests have been used to determine the boundary between extinction and non-extinction for each of several propellant formulations. these boundaries are presented in terms of the initial pressure derivative andthe initial chamber pressure.
