Abstract: Composite solid propellant slurry is a viscous fluid with high percentage of solid particles. Besides the viscosity of suspending liquid itself, those factors that influence the viscosity of solid particle suspension system are mainly the volumetrical percentage and dimensional matching of particles. This paper listed 20 expressions for calculating the viscosity of the system and discussed 4 of them, Also the paper reviewedthe effect of particle shape, size and surface property on the viscosity.And for the slurry of composite propellant with large amount of solid particleS,the values of viscosity measured with different viscometers may be quite different and slight nonuniformity in slurry may cause great deviation of viscosity.
