Procedure for the Continuous Sampling and Measurement of Non-Volatile Particulate Matter Emissions from Aircraft Turbine Engines (Includes Access to Additional Content)
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. ARP Section This document is divided into the following Sections: 2. Reference@ Definitions@ Terminology@ and Units 3. Introduction 4. nvPM System General Description@ Measurement and Losses 5. Sampling System Detailed Requirements 6. Particle Mass Measurement Requirements 7. Particle Number Measurement Requirements 8. Calculation of Emission Indices 9. nvPM System Operation A. Appendix
