Emission Measurements of a J93 Turbojet Engine

Abstract

Exhaust gas emission measurements were made at the nozzle of a J93 turbojet engine at simulated flight conditions from sea-level static to Mach 2.0 at 75,000 ft and Mach 2.6 at 65,000 ft. Real time measurements of CO, CO2, CxHy, NO, and NOx were taken over a range of after-burning and nonafterburning engine power settings using a gas sampling system designed to adhere to SAE ARP 1256 specifications. In addition, NO and OH were measured in situ by a narrow-line UV spectral absorption technique. Batch-type measurements of particulates and other trace constituents of the exhaust gas were also made. Major results of the test were that emissions vary significantly with combustor inlet pressure and temperature and, therefore, with Mach number and altitude.
