Abstract
Abstract 1. A solid composite type propellant composition comprising as a base propellant an oxidizer, a metallic fuel and fuel binder and between 0.1 and 10% by weight of a ferrocene plasticizer that is selected from the group consisting of mono- and di-substituted ferrocenes wherein the substituents are selected from the group consisting of -R, -COR, -CO2R, -CH(OH)R, and -CH(R'CO2)R wherein R and R' are selected from the group consisting of alkyl, cycloalkyl, alkenyl and cycloalkenyl radicals, the carbon chains of which may be interrupted by oxygen.
