A Method for Reducing the Viscosity of Aluminum Gelled Fuels.

Abstract : The patent application relates to a method for degelling gelled hydrocarbon fuels in order to produce a product which can be used in aircraft propulsion. Increased safety, in the case of an aircraft crash landing or crash, could be gained if the currently used liquid fuels were replaced by gelled fuels. It has now been found that the sensitivity of gelled fuels toward amines and alcohols--and especially amines--can be used to advantage in the field of aircraft propulsion. According to this invention, metered amounts of gelled JP-4 and JP-5 are subjected to metered amounts of certain amines and are thereby degelled just prior to injection into an aircraft engine for propulsion purposes. Certain alcohols can also be used but are less desirable than amines.
