The work presented here is a study of two new digital methods for determining the burning rate of a solid propellant sample using the ultrasonic pulse-echo technique. Previous work in laboratory-scale burning rate measurement is reviewed with an emphasis on the pulse-echo technique. The two new digital methods, which are named the "Digital Zero Crossing Method" and the "Digital Cross Correlation Method", are explained along with a background on the equipment used in conjunction with these methods. The two new methods are then compared to the original analog method of determining the solid propellant burning rate. From the results, the two new digital methods are more reliable than the analog methods, and parallel research shows these methods to be within 5% of the original analog method.
