Abstract:

The purpose of this program was to determine, by combustor rig tests and data evaluation, the effects of the high density fuel properties on the performance and durability of the Allison T56-A-15 combustion system. Four high density fuels in addition to baseline JP4 were evaluated in the effort. The rig test program included nozzle flow bench testing, aerothermal performance and wall temperature, flame stability and ignition, injector coking and plugging, and flow transient effect. The data evaluation effort involved the utilization of empirical correlations in addition to analytical multidimensional tools to analyze the performance of the combustor. The modifications required to optimize the performance with high density fuels were suggested and the expected improvement in performance was evaluated. Keywords High density fuel Gas turbine combustion Fuel atomization Combustor durability Emission Lean blowcut Ignition.
