Abstract: The composite solid propellants containing 50μm Al powder as a combustible ingredient are described. An excellent aggregation composed of 50μm Al powder and a large quantity of finer particle size of oxidizer (AP) ameliorats the Theological characteristics of propellant slurry and increases the burning rate. The burning rate of the strand and the propellants in a test motor with φ118 diameter increases by 2-3mm/s with the addition of 50μm Al powder compared with the addition of 30μm. The effects of 50μm Al powder on the burning rate and propellant technology are discussed.
