Abstract:

The objective of the study was to develop criteria for use in the design of aircraft gas turbine combustion chambers to minimize nitrogen oxide emissions. The approach adopted involved the development of a mathematical model of NOx emission from aircraft engine combustors a parametric analysis, using the model, to determine the sensitivity of NOx emissions to variations of model parameters and engine design variables evaluation of critical model parameters by means of experimental measurements and the incorporation of the model into combustor design methods to provide guidelines for minimizing NOx emission while maintaining other performance and emission characteristics. The report describes the nitric oxide formation process and a computer program NOXRAT for calculating thermodynamic data. The program is based upon a six- reaction model of NO formation.
