| Abstract | Alternative jet fuels (Fischer-Tropsch fuels and Biomass derived fuels) lack aromatic compounds and does not provide the desired seal-swell characteristics and other needed "fit-for-purpose" (FFP) properties. The research need is to investigate the effect of alternative fuels and fuel blends on elastomer seals in a simulated turbojet engine environment. In light of this research need, this paper describes the laboratory bench top apparatus that evaluates the engineering performance of elastomer o-rings exposed to alternative fuels and fuel blends under dynamic conditions. The three elastomer materials selected for dynamic tests were Fluorosilicone, Viton, and Buna-N o-rings. The performance of the elastomer o-rings was determined in terms of failure time that was based on fuel leakage past the o-ring seals. Pre-test and post-test elastomer properties were measured. Performance-property envelopes were used as a metric to compare different elastomer materials exposed to the same fuel and further investigate the effect of different alternative fuels on elastomers under dynamic conditions. This paper presents and compares the results from the alternative fuel (R8) and a 50/50 blend containing R-8-JP-8 on all three elastomer materials in terms of performance-property envelope charts. |
