Abstract : A need exists for a birefringent material, having phenomenological characteristics similar to solid propellants, which can be used in photoelastic studies for grain design in rocket engines. The preliminary investigations indicate that tolylene di-isocyanate polyurethane would be a satisfactory and useful photoelasticstudies of internal displacements in solid propellant grains 9embedded particlematerial for grain design applications.
