RESEARCH ON COMBUSTION OF SOLID PROPELLANTS
Abstract
The report describes theoretical and experimental studies to evaluate the effects of surface reactions on the acoustic response function of composite solid propellants. The AP oxidizer crystals were coated and the results showed coatings of Kel F and Viton reduce the acoustic response, the reduction increasing with increasing coating level. The effect of binder and curing agent on the response function was also investigated. Studies were also made on the effect of pressure on a carboxy-terminated polybutdiene-ammonium perchlorate propellant. The results indicated that over a pressure range from 100 to 500 psia both the maximum value of the acoustic response function and the frequency at which it occurs increased with increasing pressure. On the theoretical side the predictions from the model agreed well with experiment. Progress was made on the nonlinear analysis also.
