Preparation and Characterization of Gel Propellants and Simulants

Energetic gels were selected, prepared, characterized and tested for their feasibility as candidates for rocket propulsion and other gas generation systems. For fuel gellation both organic and inorganic gellants were considered. Oxidizers were gelled using inorganic gellants. In addition, gelled propellant simulants were selected and prepared to represent the relevant rheological properties of the actual fuels and oxidizers, and to aid the development of the necessary handling infrastructure for gels. The program for propellant gels and gel simulants characterization, classification, and matching in support of the prospective applications of energetic gels is also described. A capability was demonstrated to prepare gel fuels and oxidizers Theologically matched to each other as well as inert simulant gels matched to propellant gels.
