The viscosity and mechanical property of composite solid propellant are profoundly affected by sphericity of AP. In HTPB/AP propellant fomulated by two mode of AP size such as 190 ~ 200㎛ and 5 ~ 7㎛, the propellant was found to be much less viscose at end of mix when be nearly sphere of large size AP is effected of bearing in propellant.. It was shown that the strand burner test for HTPB/AP propellant with the increased in sphericity of AP. Considering both lower viscosity and stable rate of burning, the optimum sphericity of AP was estimated to be 2.0(measured to specific surface area)
