Characterization of JP-8/SiO2 and RP-1/SiO2 Gels

For next generation air-breathing and rocket propulsion systems gelled propellants can be a promising replacement for conventional solid and liquid propellants. Especially for rocket engine operation, the application of a gelled fuel and gelled oxidizer can combine the advantages of conventional solid and liquid propellants without taking into account the specific disadvantages of both individual systems. The present publication describes the rheological behavior of gelled JP-8 turbine fuel and gelled rocket propellant RP-1 when fumed silica is used as a gelling agent. Alongside the determination of an optimal gel mixing process, gel stability and rheological parameters showed a significant influence of the added silica amount.
