Abstract:
This report describes a program inaugurated to test the compatibility of aircraft fuel system materials with a JP-8 fuel containing a new thermal stability additive TSA package. The JP-8 fuel containing this new TSA is commonly referred to as JP-8100. The 100 refers to the expected 100 deg F increase in thermal stability range of fuel containing the additive over the thermal stability range of JP-8 fuel. In this test report, the effects of fuel containing BetzDearborn - 8Q462 TSA JP-8100 in thermal and x 4 concentrations levels on over 222 different aircraft fuel systems materials are measured in comparison to the effects of JP-8 fuel on the same materials. The BetzDearborn - 8Q462 fuel additive package incorporates a dispersantdetergent, a metal deactivator and an antioxidant compound which reduces the rate of oxidation and deterioration of fuel at higher temperatures. Within airframe and engine fuel systems and fuel storage and handling equipment, materials including metallics, elastomers, composites and other nonmetallics are found in contact with aviation fuel. This report describes many of these materials and physical property changes observed in these materials after thermal aging in aviation fuel containing the BetzDearborn - 8Q462 TSA package in laboratory experiments.
