摘要
The burning rate of a composite solid propellant comprising ammonium perchlorate and a fuel binder such as polysulfide, polyurethane or polybutadiene can remarkably be increased by the addition of a small amount of FeOOH. Considering the mechanical properties of the propellant, the maximum amount of FeOOH is preferably limited to 7 Wt % of the toatal of the fuel binder and ammonium perchlorate. It is possible to jointly use FeOOH and Fe.sub.2 O.sub.3 on condition that the weight ratio of FeOOH to Fe.sub.2 O.sub.3 is at least 10:90 and that the total weight of FeOOH and Fe.sub.2 O.sub.3 is in the range from 0.9 to 7% of the total weight of the fuel binder and ammonium perchlorate.
