Measurement of Pollutant Emissions from an Afterburning Turbojet Engine at Ground Level. Part I. Particulate Emissions

摘要

Smoke emissions were measured in general accordance with the methods specified in the Society of Automotive Engineers Aerospace Recommended Practice 1179. Measurements were made from 1 in. to 32 ft aft of the nozzle exit along the engine centerline, and both horizontally and vertically across the exhaust plume. The J85-GE-5 turbojet engine was operated over a power range from idle to maximum afterburning. The effects of inlet temperature and humidity on smoke production were determined, and trends of smoke production versus power setting were established. (Author)
