The examination results of composite rocket propellant composits with three different fractions of ammonium-perchlorate particle size: 200 mm, 400 mm and 80 mm and constant total solid content are presented in this paper. Burning rate and pressure exponent in the burning rate law (ballistic measures) as well as tensile strength and strain at maximum load (uniaxial mechanical characteristics) were calculated as responses according to the method of local simplex - lattice planning of the partial third series.
Key words: composite solid propellant, ammonium-perchlorate, burning rate, exponent of burning rate, planned experiment, tensile strength, strain.
