N2 - Thermal decomposition properties of hydrogen storage alloy/AP/HTPB propellants are studied by TG-DTG, DSC and kinetics analysis methods. The results show that compared to Al/AP/HTPB propellant, the thermal decomposition temperature of hydrogen storage alloy/AP/HTPB propellant is low, and its heat release is high; the condensed phase reaction degree of A20/AP/HTPB propellant is increased by 2.44%, whereas the thermal decomposition activation energy (Kissinger method) of its second and third temperature zone is decreased by 4.06% and 22.63%, respectively; the condensed phase reaction degree of A30/AP/HTPB propellant is increased by 10.61%, whereas the thermal decomposition activation energy (Kissinger method) of its second and third temperature zone is decreased by 30.89% and 38.87%, respectively. It was found that there is a catalytic effect of hydrogen storage alloy on the thermal decomposition of AP/HTPB propellant, and the catalytic effect inereased with an increase in the content of (Mg 0.45Ni 0.05B 0.5H x).
