Chemical and Physical Study of Fuels Gelled with Carbohydrate Resins
Abstract:
A carbohydrate derivative was designed as a gelling agent for turbine fuel. The gelling agent is effective in reducing the fire hazzard of the fuel. The free flowing gelled fuel could be adapted readily to existing fuel systems. The rheological profile of this gelled fuel was established over a range of conditions, by means of a rotating viscometer, Rotovisco Viscometer, equipped with special measuring heads. Among the rheological parameters which were measured, the viscoelasticity of the gelled fuel appears likely to be a major factor in contributing to the crash-safe character of the fuel. Pertinent physical properties and microbiological data were also compiled to demonstrate that the fuel gelled with the carbohydrate based gelling agent is compatible with present aircraft fuel systems.
