Hydrogen-Fueled Turbine Boat Demonstration 770797

One of two United Aircraft of Canada Ltd Model ST6B-68 gas turbine engines, that power a 36-foot Swimmer Reconnaissance Craft, was modified to burn hydrogen fuel. The fuel nozzles and sheaths of the natural gas conversion kit were modified to eliminate combustion chamber hot spots and a higher sparking rate igniter helped eliminate “pop” starts.The hydrogen-fueled turbine was safely operated at full power with a cooler combustion chamber liner than was exhibited when burning diesel fuel. No hydrogen fuel-related problems occurred during boat operation.
