Abstract: This paper, on the basis of literature survey, described the preparation and coating process of porous ammonium perchlorate (PAP) in USA and Taiwan of China.The fluidized bed technology on a laboratory scale was clearly shown in a diagram. The results proved that the burning rate of the composite propellant could be greatly raised by PAP partially substituting for the AP and became greater by more PAP while the mechanical properties of the propellant kept unchanged.The burning rate of the super-speed burning composite modified double base propellant with 34 - 38% PAP was about three times than that with no special catalyts.
