| Abstract: |
| A method to predict storage life of propellant by means of ageing data of both strength and percentage elongation is studied in this paper. Based on the ageing experimental results, the ageing dynamic equation of HTPB propellant is obtained. A calculation and reliability analysis for propellant storage life are also presented. |
