Abstract: By DSC and PDTA method, the thermal decomposition characteristics of AP/KP/GAP fuel rich propellant used for the unchoked solid ducted rocket at both atmospheric and 0 5 MPa pressure was studied The action of some TMOs on the thermal decomposition characteristics of the propellant was investigated The results show that the action of the TMOs on the thermal decomposition reactions of GAP, AP and KP is different The action of same TMO catalyst is not analogous at different pressure
