| Abstract: |
| By means of various thermal analytic methods,such as DSC, DTA, TG and DTG, the thermal decomposition characteristics of the aluminum magnesium fuel rich propellant and its main ingredients were investigated The thermal decomposition characteristics of AP/KP mixture are determined by the thermal characteristics of two oxidazers However, the thermal decomposition reaction of KP in the mixture can be catalyzed by AP decomposition The thermal decomposition process of the aluminum magnesium fuel rich propellant is a combination of the thermal decomposition reactions of AP, KP and the HTPB binders |
| Key words: Solid propellant Oxygen poor fuel rich propellant Composite propellant Thermal decomposition Thermal analysis |
