PHOTOTHERMOVISCOELASTIC ANALYSIS OF A CASE BONDED ROCKET GRAIN,

Abstract

An experimental program was performed to obtain meaningful data on transient thermal stresses in a case bonded circular port rocket grain model for correlation with theory. Both the experimental procedure and the theory were developed as part of the program. Consequently the reliability of the experimental data ultimately must await comparison of the data with the newly developed theory. The data reveal the progress of the thermal stress field from the inception upon a cold (and essentially elastic) grain through the transition to a warm (and principally viscoelastic) grain. The data were reproducible and are considered to be scientifically meaningful (Author)
