Abstract : An investigation was conducted, using the Phillips 2-Inch combustor operating under conditions simulating those in modern aircraft turbine engines, to provide information on the effects of hydrocarbon type and fuel volatility on flame radiance and exhaust emissions. Fuels used in the investigation were a JP-5 for reference and ten pure hydrocarbons (normal, iso-, and cycloparaffins and aromatics) with various boiling points within each hydrocarbon type. Hydrogen content of the fuels ranged from 7.7 to 16.4 weight per cent. The effects of differences in physical properties of the fuels were minimized by prevaporization before introduction to the combustor and maximized by using pressure atomization for injection of fuel to the combustor. Inlet air humidity was included as an operating variable. Empirical equations, based on fuel and operating variables were developed for prediction of flame radiance, NO, NOx, CO, and smoke.
