Examination of JP-8 Fuels for Contaminants Responsible for KC-130J Nozzle Fouling

Abstract

This examination was conducted at NRL to determine if fuel contamination was responsible for premature fuel nozzle coking on USMC KC-130J and USAF C-130J aircraft deployed in Iraq. The overall chemical compositions of the 26 JP-8 samples were found by chemometric modeling to be within the range of compositions determined in the 240 worldwide JP-8, JP-5, and Jet A fuels currently in our reference fuels database. This result was obtained from analyses by both gas chromatography and NIR spectroscopy. The analysis did reveal normal batch to batch variations between the fuels sampled from the storage facility at Aqaba and those sampled further down the supply chain at the Al Asad airbase. Further analyses by GC, NIR and GC-MS did not detect the presence of detectable levels of any contaminants or otherwise abnormal fuel components, including the dust abatement polymer used at this airbase.
