GAS TURBINE AND JET ENGINE FUELS

Abstract

The primary effort has been evaluation of the effects of fuel sulfur and ingested sea water on hot gas corrosion of turbine inlet guide vanes using specimens fabricated from five typical current-generation alloys including Udimet 500, Waspalloy, Rene 41, Hastelloy R-235 and Haynes Alloy 25. A second project consisted of a study of test methods for evaluating the burning quality of jet fuels. Twelve-hour duration tests were conducted with the Phillips 2- Inch Research Combustor operated at a pressure of 12 and 2000F exhaust gas temperature showed that: (1) guide vane metal loss is approximately a linear function of time; (2) a fuel sulfur content of 1.0% had no detrimental effect on the rate of metal loss; (3) only Haynes Alloy 25 exhibited significantly more loss in tensile strength with sulfur than without; (4) all alloys suffered marked losses in ductility, though no sulfur effect was indicated; (5) photomicrographs suggested predominantly intergranular attack, which was not increased by the addition of sulfur to the fuel.
