Abstract

The effects of nanometer-PbCO3 on combustion behavior of NEPE solid propellant have been studied. The compatibility of nanometer-PbCO3 and nitrate ester, as well as the effects of nanometer-PbCO3 on the curing reaction and on the thermal decomposition behaviors of ammonium perchlorate and nitroamino-compounds were studied by Differential Scanning Calorimetry (DSC). It was found that nanometer-PbCO3 exhibited good compatibility with nitrate ester which had observable acceleration on the thermal decomposition of nitroamino-compounds and on the curing reaction but little effect on ammonium perchlorate. When nanometer-PbCO2 was applied to NEPE solid propellant, the pressure exponent were effectively brought down to 0.54 and 0.52 with which content was 1% and 2% respectively.
