Aircraft Exhaust Nonvolatile Particle Matter Measurement Method Development

2018-11-20
CURRENT
AIR6037A
This report provides current practice measurement methods for quantifying nonvolatile particle matter at the exit plane of aircraft gas turbine engines. This document contains detailed information for many instruments and techniques, described in AIR5892A, that have been applied in aircraft engine field tests since AIR5892A was first issued in April 2003. There are four sections, identified as Technical Appendices (TA), presenting measurement techniques, sampling, and quantification of nonvolatile particles. The sections are written in the format of Aerospace Recommended Practice (ARP) documents and intended to progress to recommended practices upon overcoming existing technical challenges.

Procedure for Sampling and Measurement of Aircraft Propulsion Engine and APU Generated Contaminants in Bleed Air

2018-11-12
CURRENT
ARP4418B
This ARP outlines recommended practices to quantify the concentrations of a subset of bleed air contaminant marker compounds on an aircraft propulsion engine or APU prior to delivery and installation on civil and military aircraft. Testing is specified during steady state (non-transient) operation only, in a ground level test bed. Included are recommended test setup, test procedures, techniques for sampling ambient air and bleed air, and one or more specific analytical methodologies for each of the suggested bleed air contaminant marker compounds at quantification levels, given practical constraints.
