Analytical Solution for a Multi-layer Thick Cylindrical Shell Subjected to Axial Inertia Applicable for Slump Estimations of Solid Propellant Rocket Motor Grains
Renganathan K., , B. Nageswara Rao and M.K. Jana

Abstract:
A simple procedure was established to obtain analytical solution for the general case of multi-layer thick cylindrical shell with each layer having different material properties under axial inertia loading. Design formulae in handbooks or monographs for a two-layer reinforced propellant grain, was shown to be a special case of the present general analytical solution. The solution of the problem was found to be useful for slump displacement evaluation of the propellant grain in a rocket motor under vertical storage condition. The slump displacement at the inner bore of the propellant grain was found to increase rapidly within an hour and later on increases slowly with time. When the elastic modulus varied monotonically in the ascending order from the inner radius to outer radius, the slump displacement at the inner bore of the propellant grain was found to increase compared to the case where the modulus varied monotonically in the descending order. Finite element solutions of all the above problems were found to be in good agreement with the present analytical solutions.
