This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 oxygen (O2) is generally accepted as essential for assessing data quality, but is not covered by this ARP. Sulfur dioxide (SO2) is normally not measured using conventional systems but is calculated from fuel sulfur content. Again this is not covered by this ARP. Define the set point temperature range of the hydrocarbon analyzer.

Book excerpt: This SAE Aerospace Recommended Practice (ARP) describes recommended sampling conditions, instrumentation, and procedures for the measurement of non-volatile particle number and mass concentrations from the exhaust of aircraft gas turbine engines. Procedures are included to estimate sampling system loss performance. This ARP is not intended for in-flight testing, nor does it apply to engines operating in the afterburning mode.This ARP is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. This Aerospace Recommended Practice (ARP) consists of methodologies for the measurement of non-volatile particulate matter (nvPM) emissions sampled at the exit plane of aircraft gas turbine engines. The methods describe means of sampling and measuring particle mass concentration, particle number concentration and reporting of emissions indices through the use of an appropriate sampling system and instrumentation that goes beyond the measurements of visible obscuration as described in ARP1179 for Smoke Number (SN). This ARP allows for repeatable and traceable measurements of nvPM mass and number concentrations at the end of the prescribed sampling system, and it provides technical details for the measurement of nvPM emissions required for engine certification consistent with ICAO Annex 16 Volume II (see 2.1.3.14).1.

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. ARP1179 was originally developed in 1970 (with subsequent updates) as the measurement technique for Smoke Number (SN) that has been used as the basis of regulatory standards for ensuring that the exhaust plumes from aircraft engines are essentially non-visible. It has, and still does, serve this purpose.More recent concerns relate to the health and climate impacts of particulate matter emitted by aircraft engines. Particle size, number and mass are all seen as relevant parameters as is the issue of "volatility".The SAE E-31 Committee is currently using all its resources in developing a new ARP on the mass and number measurement of non-volatile particles at the exhaust of aircraft engines.Hence the Committee recommends keeping ARP1179 as it still serves its purpose of quantifying the visibility at the exhaust of aircraft engines; it does not recommend any revision of it.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Aerospace Information Report (AIR) describes the use of FTIR analyzers for measurements of gaseous emissions from aircraft gas turbine engines and combustion rigs. The use of FTIR analyzers can be demonstrated as a suitable and cost-effective equivalent to NDIR and chemiluminescence analyzers as prescribed in ARP1256 for the measurement of CO, CO2, NO, and NO2, where NOx is closely approximated by the sum of NO and NO2 concentrations. FTIR analyzers may be proven suitable for equivalency of analyzers used in current emission testing. Additionally, FTIR analyzers have potential for equivalent measurements of "total" hydrocarbon (THC) as currently defined in ARP1256. Fourier transform infrared (FTIR) analyzers can measure gaseous emissions from combustion sources with similar accuracy to present non-dispersive infrared (NDIR) and chemiluminescent-type analyzers recommended by ARP1256 and required by ICAO Annex 16 Vol II. This Aerospace Information Report (AIR) summarizes experience in the use of FTIR instruments in measuring aircraft gas turbine engine and combustion rig exhaust effluents by extraction. The intent of this AIR is to discuss the FTIR analysis method and document the use of FTIR gas analyzer instrumentation prior to development of a future FTIR ARP document. Adoption of FTIR instruments in a measurement system will reduce the number of analyzers currently necessary and may provide the capability to measure detailed hydrocarbon species.

This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Information Report (AIR) addresses procedures applicable to quantifying the emission of nonvolatile particulate matter at the exit plane of aircraft gas turbine engines. While both volatile and nonvolatile particulate matter (PM) are present in aircraft gas turbine exhaust, the methods used to measure nonvolatile particles are farther advanced and are addressed here.Existing PM measurement regulations employ the SAE Smoke Number measurement (Reference 2.1.1), a stained filter technique used in evaluating visible emissions. The environmental and human health issues associated with submicronic PM emissions require more detailed measurement of the mass, size, and quantity of these particle emissions.Responding to regulatory agency requests, this AIR describes measurement techniques that are well developed and could be applied to the measurement of aircraft engine particulate matter. The techniques discussed here are considered relevant for measuring particle parameters identified with environmental and health concerns.The discussion that follows is based on research made while developing measurement techniques and in scientific and engineering experiments regarding PM emissions. The techniques are not yet used in routine aircraft engine certification. Future use in regulatory testing is likely to involve further refinements in methodology and application. It is planned that these refinements will be included in the subsequent publication of an Aerospace Recommended Practice.The distinction between nonvolatile and volatile particle types is a critical task in the measurement of particles in aircraft engine exhaust. Appendix A, SAE E-31 Position Paper on Particle Matter Measurements, provides additional technical bases for the scope of this AIR. The measurement methods for volatile condensed particles in turbine exhaust will be covered in a subsequent report. Observations to date show that volatile particles occur mainly at diameters less than 10 nanometers (
