Modeling and rheology of HTPB based composite solid propellants
AbstractThe propellant with the minimum viscosity required for a defect‐free casting can be obtained by proper selection of the size and fractions of solid components leading to maximum packing density. Furnas' model was used to predict the particulate composition for the maximum packing density.
