Abstract
An afterburning turbofan engine was operated over a range of simulated altitudes and Mach numbers to determine if correlation existed between static sea level emissions and those at altitudes and flight speeds. Data were taken at a point about 27 feet downstream of the exhaust nozzle exit and on the centerline of flow. No apparent effect of altitude or flight speed on emissions, either gaseous or particle, was observed.
