| Abstract: |
| The relationship between the oxidation reaction heat effect of HTPB propellants gel and mechanical properties of HTPB propellants during storgae aging was studied.The results indicate that during storage aging the oxidation reaction heat effect has a good linear relationship to the strain under ultimate tensile strength of propellant.This provides a small quantity,quick simple and convenient new method for the storage life of HTPB propellant estimation. |
