Estimates of oxides of nitrogen formed in the inlet air stream were made for the forebody and internal sections of a generic inlet operating at high-speed flight conditions. Computational fluid dynamics analyses were used to compute typical inlet flow fields. Oxides of nitrogen levels were calculated using these flow fields together with a reaction rate mechanism and a chemical kinetics code. It was found that significant amounts of these species are produced only in a small region of the air flow captured by the inlet and located near its surfaces.
