Contents Notes
Laser induced Raman and fluorescence measurements were made in the exhaust of a T53-L13A gas turbine engine with a new field portable instrument devised specifically for gas turbine exhaust emission measurements. The gas turbine exhaust was analyzed by conventional instruments for CO, CO2, NO, NOx, total hydrocarbons, smoke and temperature, and these data were used as a 'calibration' standard for the evaluation of the laser Raman instrument. The most severe problem area was laser induced hydrocarbon fluorescence when the exhaust contained large total hydrocarbon concentrations. The overall conclusion was that the laser Raman method shows a good potential for aircraft gas turbine emission analysis.
