Definition of Aviation Turbine Fuel Contamination under Simulated Combat Conditions
Abstract
JP-4 drain samples were obtained from Army aircraft, tank trucks, and other points in the fuel supply system at six field exercises under intensive training conditions. The samples were analyzed for particulate contaminants and compared to the contaminants package for test fluids used in aviation gas turbine engine component and systems qualification testing under AV-E-8593B. Results indicate that (a) the vast majority of samples had contamination concentration levels several orders of magnitude less than the AV-E-8593B package, (b) an unexpectedly high number of aircraft drain samples (roughly 7 percent) and numerous points in the refueling systems showed concentrations far exceeding this package. Both the quantities and chemical nature of these particulate contaminants indicate that the AV-E-8593B package is realistic and representative of contamination which can occasionally occur in field Army operations. The utilization of this contaminants package therefore provides suitably stringent criteria for bench test qualification of aviation gas turbine engine fuel system components.
