CRITICAL REVIEW OF METHODS FOR REGRESSION RATE MEASUREMENTS OF CONDENSED PHASE SYSTEMS

Abstract

Accurate measurement of the steady-state and transient burning rate of solid propellants and other energetic materials are important for evaluating the performance of propulsion and/or gas generator systems. Numerous burning rate measurement methods have been developed by various researchers in recent years. This paper provides a critical review of the existing techniques, including the basic physical principles utilized for burning rate determination, an estimate of their temporal and spatial resolutions, and their special merits and limitations. Recommendations for special applications of certain methods are also provided.
