Barium salicylate and/or other organobarium salts, barium oxide, and organometallic salts of lanthanum, hafnium, and tantalum and oxides of the same are used as ballistic modifying means for solid propellants. The specific ballistic modifying means can be used as replacements for the lead, copper, etc., compounds currently employed as ballistic modifiers in solid propellants. The propellants containing the specified ballistic modifying means retain the highly desirable plateau-burning characteristics, pressure exponents, and temperature coefficients but are particularly attractive because they produce considerably less smoke during the burning thereof. |
