TL;DR: Nonintrusive systems for the measurement on test rigs of aeroengine exhaust emissions required for engine certification, together with CO(2), CO, and NO data showed agreement with intrusive techniques of approximately ?
Journal ArticleDOI
Soot volume fraction measurements in aero-engine exhausts using extinction-calibrated backward laser-induced incandescence
J. Delhay,Pascale Desgroux,Eric Therssen,Henrik Bladh,Per-Erik Bengtsson,H. Hönen,John D. Black,I. Vallet +7 more
TL;DR: In this article, a modified version of the laser-induced incandescence (LII) system was developed to achieve reliable and quantitative soot volume fraction measurements in the exhausts of aero-engines.
Journal ArticleDOI
2D imaging of laser wing effects and of soot sublimation in laser-induced incandescence measurements
TL;DR: In this article, the distribution of LII signal in sooting flames along the laser beam is imaged using two directions of observation: one counter to the propagation direction of the incident laser (backward LII) and one at right angles.
Journal ArticleDOI
In-situ laser-induced incandescence of soot in an aero-engine exhaust: Comparison with certification style measurements
John D. Black,Mark Johnson +1 more
TL;DR: In-situ (nonintrusive) laser-induced incandescence measurements of soot in the exhaust of a mid-size turbofan aero-engine running on a sea-level test bed have been performed at the same time as the extractive measurements required for engine emissions certification.
Journal ArticleDOI
Development of techniques to characterize particulates emitted from gas turbine exhausts
TL;DR: In this article, an intrusive sampling system conforming to current ICAO regulations for aircraft emissions was used with a scanning mobility particle sizer (SMPS) and non-intrusive measurements were made using laser induced incandescence (LII) and samples were taken from the exhaust to analyse using a transmission electron microscope.
