n this paper,thermal analysis method is applied to select two cupric catalysts,and the effect of those catalysts in RDX/HTPB propellant formula is studied experimentally.The acoustic radiating method is used to measure burning-rate of the propellants under the pressure condition of 4-8MPa.From the experimental results,it canbe seen that the two new cupric catalysts are effective,they can improve burning-rateby 42%,lower burning rate pressure exponent by 14%,If the catalysts are composedproperly,they can improve burning rate and lower burning-rate pressure exponentmore.
