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)
