Non-Intrusive Measurements of Aircraft Engine Exhaust Emissions

Obiettivo


The main result of the project is the demonstration of the capability of taking non-intrusive species measurements in a jet/plume and the comparison of these were certified intrusive measurements. The conventional intrusive measurements were performed by DERA with a spatial resolved method using a traversing single-point sampling probe. A modified mid-size low by-pass aero-engine running on a sea level test bed was used for the measurements. It was shown that the developed non-intrusive measurement methods have the potential to overcome the disadvantages of currently used gas sampling techniques.

Beside the optics for the conventional emission mode BUGHW developed and installed a novel open-path White mirror system in the test bed which had not yet been applied to this specific task. The compartment was the first one operated in a test rig and successfully used during campaigns.

Measurements are fast and reproducible. However, more work is required to establish their accuracy by providing a reliable calibration, and it may be necessary to change the configuration to allow spatially resolved measurement to remove errors due to assumptions about particle distribution in the plume. These issues are being addressed in AEROJET2.
Objectives and content

The environmental impact of air traffic and economical aspects require aircraft engines with reduced trace gas emissions, small specific emissions, and simultaneously increased efficiency. The in-time development of appropriate combustors and turbines will improve the compatibility of the European aircraft industry on the international market. Non-intrusive measurements are the method of choice promising to avoid disadvantages of currently used gas sampling techniques. The consortium of partners has already experience in determining exhaust gases by non-intrusive techniques. R & D performers (Fraunhofer Society, University of Reading, University of Wuppertal, German Aerospace Establishment, and Defence Research Agency from UK) co-operate with developers (Auxitrol) and end-users (Rolls Royce, British Aerospace).

Fourier Transform Infrared and Narrow-Band Spectroscopy are proposed as non-intrusive measurement techniques for analysis of aircraft engine exhaust emissions in industrial test rigs. Basic investigations, utilizing a variety of spectrometers, measurement modes and analysis procedures will allow cross validation of the methods and intercomparison with conventional techniques. The objective is to identify the most appropriate and versatile nonintrusive technique and instrumentation able to replace the current intrusive methods for industrial operational use.

The 2-years project includes development of measurement hardware and engine test rig measurements to validate these non-intrusive with the intrusive measurement methods. For data interpretation of the non-intrusive techniques it is planned to develop the inversion methods further and to extend the high-temperature molecular database by laboratory measurements.
