From a view point of safety measure against the fire hazard involved with aircraft crash or ditch and singular hydrodynamical fluid motions in space flight and refueling with liquid rocket tankage, feasibility of gelled hydrocarbon fuels and propellants is discussed. It is concluded that O/W (oil-in-water) type gelled hydrocarbons are most promising as the safety fuels, resulting from a comparison in the rheological and combustion properties with the other gelled fuels; slurry, scaffold and thickened (highly viscous) ones. Physical properties and flammability of very high internal phase ratio gelled JP-4 and kerosene, ranged 96 to 99 vol% fuel content, and of N2H4/JP-4 gelled propellant developed by ISAS, Univ. of Tokyo and Mitsubishi Oil Company are described.
