| Abstract: |
| With dynamic viscoelasticity testing device DDV-III-EA the dynamic viscoe-lastic properties of Sco-1 solid propellant samples are measured, Main curves and formulae of complex modulus E*(ωaT) as well as stress relaxation modulus E (f/ aT ) are obtained through computerisation and analysis based on the principle of frequency-temperature (time-temperature)equivalence, and relations between dynamic and static viscoelasticities. This paper is available to the analysis and the computation of graim structural integrity in solid rocket engines. |
