On 1 November 1958, an experimental program was begun to determine the longitudinal and bending dynamics of structures simulating large, solid-propellant rocket engines. Equipment was ordered, and experimental design configurations were developed. During the following twelve months, experiments were performed on specimens composed of thin, metal, cylindrical shells which surround and are bonded to a solid-propellant-like material inert propellants were used. The purpose of these experiments was to determine the effective mass, stiffness, and damping of the propellant when the propellant-cylinder system is undergoing longitudinal and bending vibrations.
