Application of alternative jet fuels to improve local air quality at airports: Results from ground-based measurements
Abstract
In the framework of the ECLIF/ND-MAX campaigns seven alternative jet fuel blends were employed in an IAE V2527 engine (A320 aircraft, Advanced Technology Research Aircraft (ATRA)). The emissions of particulate matter (PM) from the aircraft engines at various power settings - ranging from idle to maximum continuous thrust - were analyzed during a series of ground runs. Several particle counters and fast sizers were used to characterize the aerosol with regard to particle number and particle size distribution. The experimental setup further provided information on the volatile and non-volatile particle fractions of the PM emitted by the engines operating with the different fuels. The ATRA research aircraft records many emission-relevant engine parameters that allow the identification of possible impacts of the alternative jet fuels on emissions as a function of the key engine parameters. Furthermore, the correlation between engine operation and emission measurements allows estimating the possible impact of the aircraft operation on the local air quality. Beside the public discussion about the carbon footprint of aviation, the local air quality in the vicinity of airports is a strong driver of current emission mitigation activities. From the two ground measurement campaigns on the IAE engine, the impact may be estimated on the basis of the take-off and landing cycle (LTO). This approach reduces the complexity of the results on the basis of a near-to-real-world scenario and might be a useful tool to quantitatively estimate how different engines and their respective responses to alternative could be used to reduce PM emissions and their impact on air quality.
