The results of an analysis by Armenakas for the natural frequencies of composite (two material) cylinders is used to determine the lowest natural frequency of bonded and unbonded propellants in three-inch and five-inch rocket motors. The lowest frequency is found to be approximately eight times larger than the lowest frequency in the launch force pulse. Thus, the dynamic effects in the propellant will be significant. (Author)
