Experimental and Analytical Study of Erosive Burning of Solid Propellants
Abstract
Experimental and analytical modeling studies of the erosive burning of solid propellants were conducted at Atlantic Research and Penn State University, with additional modeling efforts at Aeronautical Research Associates of Princeton. At Atlantic Research, erosive burning characteristics of approximately 15 AP- composite solid propellant formulations with systematically varied compositions and ingredient particle sizes were determined over a wide range of pressure and crossflow velocity. It was found that the most important parameter in determining sensitivity of burn rate to crossflow is the no- crossflow (base) burning rate versus pressure behavior of the formulation. An analytical model of the erosive burning of AP-composite formulations was developed and found to yield good a prior predictions of burn rate as a function of pressure and crossflow velocity, given only composition and ingredient particle sizes. This model was also found to predict an observed decrease in crossflow sensitivity with increasing grain port diameter.
