Abstract : The present invention relates to propellant compositions and to the preparation thereof; more particularly to improved high performance gelled fuel compositions. It is an object of the invention to provide a composition with improved physical properties which can be used as a rocket propellant fuel that is safe and easy to handle. Also it is a gelled propellant composition which maintains its physical properties over a wide temperature range of -65F to 165F even after prolonged storage periods. In accordance with the present invention a small amount of a polymeric colloid sold under the trade-name 'Kelzan' was mixed into amine fuels, hydrazine, unsymmetrical dimethylhydrazine, monomethylhydrazine, and other hydrazine derivatives, and mixtures thereof. The product exhibits great cohesiveness and will pull into long thread-like strings when scooped up. It was discovered that the present new gel composition was compatible with gelled JP fuel, and gelled kerosene making this a great advance in the art which reduces the cost of the exotic fuels by mixing in less expensive fuel. The gelling agent, Kelzan, used herein, is a polymer containing mannose, glucose, potassium glucuronate and acetyl in the approximate molar ratio of 2:1:1:1.
