| Abstract | Spectroscopic analysis of metallic exhaust emissions from gas turbine engines could potentially provide valuable information about the mechanical condition of gas path components. For example, emission spectroscopy has already been implemented on liquidfuelled rocket motors where the high combustion temperature populates upper atomic and molecular energy levels of exhaust gases. To define applicable spectroscopic techniques, an elemental evaluation of the most critical components within the gas path of a General Electric CF-700 turbofan engine was completed. In addition, typical engine operating conditions were reviewed. The evaluation provided information about the nature and state of the chemical species potentially present in the gas path whereas the review considered the chance that these species might be vaporized, and hence available for detection via spectroscopic techniques. Overviews of vaporization and spectroscopic techniques are then presented. Finally, the planned experimental procedures and the major steps of the research are outlined. |
