Procedure for the Analysis and Evaluation of Gaseous Emissions from Aircraft Engines

E-31G Gaseous Committee
  • Aerospace Standard
  • ARP1533C
  • Current
Published 2016-04-13 by SAE International in United States
SAE Aerospace Recommended Practice ARP1533 is a procedure for the analysis and evaluation of the measured composition of the exhaust gas from aircraft engines. Measurements of carbon monoxide, carbon dioxide, total hydrocarbon, and the oxides of nitrogen are used to deduce emission indices, fuel-air ratio, combustion efficiency, and exhaust gas thermodynamic properties. The emission indices (EI) are the parameters of critical interest to the engine developers and the atmospheric emissions regulatory agencies because they relate engine performance to environmental impact. While this procedure is intended to guide the analysis and evaluation of the emissions from aircraft gas turbine engines, the methodology may be applied to the analysis of the exhaust products of any hydrocarbon/air combustor. Some successful applications include: Aircraft engine combustor development rig tests (aviation jet fueled) Stationary source combustor development rig tests (natural gas and diesel fueled) Afterburning military engine tests (aviation jet fueled) Internal combustion aircraft engine diagnostics (AVGAS fueled) Each application may be characterized by very different measured emissions levels (parts per million versus percent by volume) but this common approach…

Procedure for the Continuous Sampling and Measurement of Gaseous Emissions from Aircraft Turbine Engines

E-31G Gaseous Committee
  • Aerospace Standard
  • ARP1256D
  • Current
Published 2011-07-19 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) describes the continuous sampling and analysis of gaseous emissions from aircraft gas turbine engines. The measured gas species include carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), hydrocarbons (HC) and water vapor (H2O). This ARP excludes engine operating procedures and test modes, and is not intended for in-flight testing, nor does it apply to engines operating in the afterburning mode. It is recognized that there will probably be major advances in the gas analysis measurement technology. It is not the intent of this ARP to exclude other analysis techniques, but to form the basis of the minimum amount of conventional instruments (those in common industry usage over the last fifteen years) required for the analysis of aircraft engine exhaust. It is the responsibility of the analyst to demonstrate the alternative measurement technology has comparable (or better) performance than the techniques described in this ARP. The measurement of other exhaust gas species is beyond the scope of this ARP. It should be noted the measurement of…

Aircraft Gas Turbine Engine Exhaust Smoke Measurement

E-31G Gaseous Committee
  • Aerospace Standard
  • ARP1179D
  • Current
Published 2011-07-19 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) standardizes test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. Tests have indicated that the practically achievable precision of the smoke number is within ±3 when the system is properly used as outlined herein. This procedure is not intended for in-flight testing, nor does it apply to engines operating in the afterburning mode.
