Investigation of the effects of a monocyclic and several polycyclic hydroaromatic high temperature hydrocarbon fuels on flame radiation and flame tube metal durability has been conducted in a two-inch laboratory scale combustor under simulated conditions of sea-level takeoff, medium altitude cruising and high altitude loitering flight. Isoparaffinic and aromatic fuels were also included for reference purposes. Supplementary data obtained include deposition, smokiness, combustion efficiency, flame radiation in the Phillips Microburner and ASTM smoke point. Although differences in transverse flame radiation, flame tube metal temperatures and flame tube metal losses were observed among the five polycyclic hydroaromatic fuels tested, these appear significant only in the cases of isopropyl bicyclohexyl and dimethano decalin at simulated sea-level takeoff. Diethylcyclohexane, the single monocyclic hydroaromatic tested, exhibited relatively low radiation fluxes, flame tube metal temperatures and flame tube metal losses, making it appear comparable to the isoparaffinic reference fuels at all test conditions.
