GELLED PROPELLANT RESEARCH: Gelled propellants offer increased safety and insensitivity to tactical systems. The unique rheology of these fluids allows them to store as solids, with minimal leakage, yet flow as liquids. The rheology that affords those benefits also causes longer ignition delays.

Delayed ignition is dangerous and intolerable in rocket systems; for gelled propellants to be used, the ignition delay must be understood and eliminated. ORBITEC has conducted a series of programs the investigated the effect of the gel phase on the ignition process. These programs have investigated the formulation, spray formation, vaporization, mixing and hypergolic ignition. The results have generated in-depth understanding of both gelled propellant and hypergol behavior.
