The thermal decomposition process and combustion wave structure of azide polymer were studied to determine the parameters which control the burning rate. The azide polymer studied was 3‐azidomethyl‐3‐methyl oxetane (AMMO) which contains energetic –N 3 groups. From the experiments, it was found that the thermal decomposition process of AMMO consists of a two‐stage weight loss process: the first‐stage corresponds to an exothermic reaction which is caused by the scission of N‐N 2 bond, and the second‐stage corresponds to the decomposition of the remaining fragments. The burning rate of AMMO is approximately 50% of the burning rate of GAP propellant and is as high as that of conventional double base propellant. The heat feedback from gas phase to the burning surface increase with increasing pressure. The burning surface temperature and the heat of reaction at the surface decrease with increasing pressure.
