Abstract

The effect of lead and copper methylene disalicylates and their mixtures was studied on the burning rates (35 kg/cm^2^‐140 kg/cm^2^), heat of explosion, stability and thermal decomposition of double‐base propelants. The results indicate that these salts are very effective catalyst and their mixtures produce super‐rate burning (140% increase) with a uniform pressure index value in the entire pressure range. These additives lower “n” value to about 0.2–0.3 in some of the pressure regions. Results of DTA study suggest that these additives decompose in an exothermic mode in the temperature range close to the surface temperature of double base propellants.
