GAS TURBINE AND JET ENGINE FUELS

Abstract
Efforts included: (1) endurance testing of two promising new splash- cooled two-inch test combustor designs capable of operating under conditions simulating low-level tactical fighter attack missions and/or submarine search missions by a regenerative turboprop-equipped aircraft; (2) planning and statistical design of a test program to determine whether the 0.4 weight per cent maximum total sulfur now allowed in JP-5 fuel is a safe level for protection of modern turbine blading alloys from hot gas corrosion and, if not, data will be obtained to show whether lower sulfur limits will alleviate corrosion significantly. These studies will be carried on with and without ingested sea water to show whether or not fuel sulfur accelerates sea salt corrosion. The combustor design selected for this work is described.
