Abstract: The viscoelastic properties of composite solid propellant slurry,like HTPB,CTPB,polyether propellants were studied using Haake CV20N viscometer.The results indicate that the slurry is a viscoelastic fluid,dynamic complex viscosity η * appears as tendencies varied with propellant kinds,formulation characters and frequencies and the dynamic complex modulus G * ,the loss modulus G″ and the storage modulus G′ increasing with frequency.Generally, G″ is one number order more than G′ at the same frequency,in G′ there are a number of loss peaks which correspond with the tan δ peaks.A constructive model made use of explaining the viscoelasticity of slurry was suggested yet
