Abstract This report presents a set of correction factors for variations in turbine aircraft HC, CO, NOX and smoke emissions due to non-standard day ambient temperature, pressure and humidity developed for the United States Environmental Protection Agency, Ann Arbor, Michigan. These correction factors are based on data from three EPA-sponsored full-scale engine tests, two EPA-sponsored combustor rig tests, and additional data solicited from industry sources. Key correlating parameters in this analysis were combustor inlet temperature, combustor inlet pressure, and ambient humidity. The correction factors have been developed using a multiple least squares regression analysis approach using functional emissions models based upon theoretical considerations and an extensive review of current ambient effects literature. Emphasis has been placed upon relating correction factor coefficients within a general engine class to various operating characteristics of each individual engine.
