✦ Synopsis

The effect of Nd203 on thermal and ballistic properties of ammonium perchlorate (AP) based composite propellant has been studied during this work. The composite propellant batches were prepared by slurry cast technique using sigma blade mixer. Ballistic parameters were determined by acoustic emission technique. Significantly, lower pressure index values in lower pressure range (SO-70 kg/cm') and higher pressure index values in higher pressure range (70-125 kg/cm') were achieved when NdzOa was used in place of Fez03 . DSC studies suggest that NdzOa promotes exothermic reaction in condensed phase which compensate heat sink effect unlike in case of Fe203 .

Aging behavior of hydroxyl-terminated polybutadiene/ammonium perchlorate (HTPB/AP)-based composite solid propellants was studied as a function of crosslink density, which is predominantly determined by the molar ratio of diisocyanate to total hydroxyl (NCO/OH ratio) and the molar ratio of triol to d
