Abstract: The examinations of the development of composite solid propellants based on hydroxyterminated polybutadiene including titanium (IV) oxide as not only ballistic stabilizer but also ballistic modifier of these propellant types have been represented in this paper. Various compositions different in relation to solid content, coarse/fine ratio of ammonium-perchlorate powder's sizes and titanium (IV) oxide content have been made for the research. The effect of titanium (IV) oxide, along with the other ingredients of propellant, on the burning rate law's parameters have been examined.

Key words: composite solid propellant, titanium (IV) oxide, ballistic behavior.
