A study was conducted to evaluate the erosion performance of candidate motor-case thermal protection materials for advanced missiles. Available data were compiled and evaluated and empirical expressions were developed to describe the erosion performance of two of the leading candidate materials VAMAC 15J and Kevlar-epoxy. These expressions then were applied to predict the flight response of these two materials for two design flight trajectories and a simulated freestream dust environment. Finally, a number of available ground test facilities were evaluated for use in performing erosion tests of materials for ascent flight. Recommendations were made for the optimum facilities to accomplish different types of test objectives. Author
