Synthetic Fischer-Tropsch (FT) JP-5/JP-8 Aviation Turbine Fuel Elastomer Compatibility
Abstract
When some elastomer (rubber) compounds, and specifically those used for seals in fuel-wetted components of vehicles and equipment, are suddenly 'switch-loaded' from one kind of fuel to another, swell/shrink issues relating to seal performance may arise, possibly leading to fuel leakage. The key objective of this study was to compare and contrast the material compatibility of nitrile coupons and O-rings with selected petroleum-derived fuels, Fisher-Tropsch (FT) synthetic JP-5/JP-8 fuel, and blends of FT JP-5/JP-8 with various amounts of aromatic blend stock. This study provided a baseline for predicting the effects of static elastomer swell to the potential degree of swell/shrink that can be expected when fuels are 'switch-loaded' and a comparison of effects on coupons as well as O-rings which indicated similar overall trends and were in agreement with prior work. The use of an aromatic concentrate as a surrogate source of aromatics did not reveal any significant bias when compared to petroleum derived JP-5 and diesel fuel, although it was shown to have a reduced effect on elastomer change as compared to the petroleum fuels.
