Sustainable aviation fuel (SAF) offers a near-term opportunity to reduce aviation’s greenhouse gas emissions. Currently-approved SAFs are limited to a maximum blend ratio with conventional jet fuel due to materials compatibility issues (i.e., O-ring volume swell). Specifically, aircraft have been found to leak significant quantities of fuel when volume swell is insufficient. Here, optical dilatometer measurements of volume swell for SAFs are reported. These measurements will serve to screen candidate SAFs at an early stage of the approval process. Optical dilatometry measurements were also coupled with two-dimensional gas chromatography data to predict volume swell withfuel.
