The Effect of Additives on Solid Rocket Propellant Characteristics
Vesna Rodiæ Mirjana Petriæ
The effect of different additives on viscosity gradient of composite rocket propellants (CRP) based on hydroxyterminated polybutadiene (HTPB) cured with isophorone-diisocyanate (IPDI) or dimeryl-diisocyanate (DDI) containing ferry-oxide or copper- chromite and CRP based on polyurethane (PU), cured with toluene-diisocyanate containing ferry-oxide are presented in this paper. The effect of tetracycline (TC), pyrogallol (PG), diester of phosphoric acid (RM-410), acetylacetone (HAA) and curing catalyst comprising triphenyl bismuth (TFBi), maleic anhydride (MA) and magnesium oxide (MgO) on propellant viscosity and cure rate profile is also given.
Key words: composite rocket propellant, viscosity, additives, effect of additives, additive effect tetracycline, pyrogallol, triphenyl bismuth, acetyl acetone.
