Abstract : Test data for F101, J79, and TF-41 jet engines were abstracted from the literature and analyzed to determine the correlation between smoke-related engine performance data and laboratory measurements of fuel sooting tendencies. The smoke-related data included smoke number, linear temperature rise, radiation flux, and Smoke Emission Index measurements. The engine data were correlated with the following laboratory measurements of fuel sooting tendencies: fuel hydrogen percent, total fuel aromatic content, polycyclic aromatic content, smoke point, H/c ratio, C/O ratio, and several types of threshold sooting indices (TSIs). Rules for estimating TSI values for multicomponent mixtures, such as jet fuels, were developed in order to utilize the existing laboratory data for pure fuels (i.e., single chemical compounds). It was determined that no single laboratory measurement of fuel sooting tendency could be used to correlate all the selected engine test data. Improved results can probably be obtained with more accurate and complete fuel analyses as well as improvements in the procedures for estimating jet fuel TSIs.
