Abstract: Based on survey of about 40 literatures, this paper discusses the effect of fine-and superfine-grain ammonium perchloratc (AP) and ni-tramincs (RDX, HMX) on the improvement of burning performance of AP-composite propellants, nitramine-composite propellants and AP/nitramine-composite modified double-base propellants,The effect of superfine-grain and porous AP on improvement of burning performance and the effect of fine-grain nitramines on elimination of the inflexion point at the curve of burning rate-pressure are also discussed. Experimental date show that the high burning rate and high specific impulse can be achieved by using the fine-grain or superfine-grain AP propellants and nitramine propellants under the energetic condition of high effective catalyses of burning rate, polyazinc bender etc.
