Concordia researchers develop new gel fuel for rocket propulsion
Researchers at Concordia University have created a kerosene-based gel that could improve the storage and control of rocket and satellite fuels.
Gel combines kerosene with lecithin
The material mixes kerosene, lecithin, and calcium chloride to address stability issues in space propulsion. Liquid fuels often slosh inside tanks, whereas conventional gels are hard to pump into engines. This new formulation aims to balance the need for stable storage with efficient flow during injection.
Viscosity changes under force
Tests showed the substance acts like a soft solid when resting but flows easily when force is applied. Its viscosity drops significantly as it faces increasing pressure needed for fuel injection. The samples stayed stable for over a year inside sealed containers without separating.
Transparent appearance aids observation
The clear look of the gel allows scientists to watch how the fuel moves and burns. These findings help identify properties required for reliable delivery systems in spacecraft.
