Abstract: The Influence of HTPB (Hydroxy Terminated Polybuladiene) euring cross-linked system on burning rate of propellant is studied in present paper.lt was dis- covred from experiments that the burning rate of MAPO-bearing solid propellantin curing cross-linked system is ,18.4% higher than that of trialcohol cross-linkedpropellant. Its action mechanism is analysed by means of experimental methodsincluding thermal analysis and interrupting combustion etc.
