Evaluation of Shelldyne-H Fuel for Gas Turbine Engine Use
Abstract
Shelldyne-H (asterisk) fuel was evaluated with an AiResearch Model GTP30 Gas Turbine Engine, and some of its components. Fuel properties data supplied by Shell Oil Company were verified. Elevated-temperature aging tests of various elastomers indicated that Viton A, LS-53, and Buna N are compatible with Shelldyne-H fuel, and that materials containing straight silicone compounds are incompatible with Shelldyne-H fuel. Fuel control tests, including fuel-pump tests were performed at temperatures down to minus 65 degrees F. Low temperature pump cavitation was experienced. Ignition was a problem, but combustion tests revealed good efficiency and temperature distribution after combustion was achieved. Engine starts with Shelldyne-H fuel could be made above plus 10 degrees F with the use of a cartridge starter gas system. Engine starts could be made above minus 40 degrees F, if ignition was initiated with MIL-T-5624 Grade JP-4 fuel. A system problem, identified at low temperatures, was a means to get all usable fuel from the fuel tank to the engine because fuel adhered to the tank walls.
