| Abstract Using different ammonium perchlorate (AP) resources even with the same particle size distribution and the same physical and chemical characteristics have some effect on the ballistic performance of aluminized composite solid rocket propellant (Al-CSRP).The main goal of this paper is to retain the optimum characteristics performance of (CSRP) formulations after changing the AP resources either by adapting the particle size distribution of the new AP particles or by adding a catalyst. Effect of changing particle size distribution for the new source ofAP on the ballistic characteristic of (Al-CSRP) was studied in this paper but no significant effect on the goal of this work was obtained. Three burning rate modifiers (BRM) (catalysts) were added separately on the prepared (Al-CSRP) formulations to study their effect on the performance and the ballistic characteristics of these formulations. Nanosized Barium Ferrite (BF) catalyst was able to retain and recover the required ballistic characteristics of CSRP formulation containing the newAP resources, and hence the aim of this work was achieved. Thermal analysis studies were performed on the different types of AP and also on mixtures of AP with different BRM to find the optimum weight percentage of added catalyst. The required weight percentage of nano-sized BF which achieves the goal of this work was found to be 0.05-0.07% basedon the CSRP formulation mass. | ||||
