Study on Viscoelastic Characterization of Monmethyl Hydrazine Gel Propellant

Abstract

The viscoelastic characterization of monmethyl hydrazine gel propellant was tested by using rheometer. The results showed that the viscoelastic characterization of monmethyl hydrazine gel propellant was affected by temperature, stear stress and frequency. On a certain frequency, elastic factors were dominant; with the increasing of stear stress, the elastic module became stronger but the viscosity changed unconspicuous. Increasing frequency, both of viscosity module and elastic module grown, but the growing of elastic module was more fleetly; on the other hand, the storage viscosity and dynamic viscosity fell to be close. High temperature fell viscoelastic module, but af-徐红
