The interdisciplinary team, which also includes researchers from the National Research Council of Canada and The University of Manchester, plans to publish its results in academic journals towards the end of next year and 2023.<\/p>\n\n\n\n<p>Findings from the study will support efforts currently underway at Airbus and Rolls-Royce to ensure the aviation sector is ready for the large-scale use of SAF as part of the wider initiative to decarbonise the industry. Aircraft are currently only allowed to operate on a 50% blend of SAF and conventional jet fuel, but both companies support the drive to certify 100% SAF use.<\/p>\n\n\n\n<p>In April, the A350 flew three flights over the Mediterranean Sea pursued by a DLR Falcon chaser plane to compare in-flight emissions of both kerosene and Neste\u2019s hydro-processed esters and fatty acids (HEFA) sustainable fuel. The team also carried out compliance tests using 100% SAF and no operational issues were experienced.<\/p>\n\n\n\n<p><strong><em>\u2192 <a href=\"https:\/en\/2021\/11\/pratt-whitney-launches-new-series-engines.html\">Pratt &amp; Whitney launches new series of engines that will power ATR aircraft.<\/a><\/em><\/strong><\/p>\n\n\n\n<p>In-flight emission tests using 100% SAF and a HEFA\/Jet A-1 fuel blend resumed this month, while ground-based emissions testing to quantify the benefits of SAF on local air quality were also performed. The research team found SAF releases fewer particulates than conventional kerosene at all tested engine operating conditions, which points to the potential for reduced climate impact and improvement in air quality around airports.<\/p>\n\n\n\n<p>In addition, SAF has lower density but higher energy content per kilogram of fuel compared to conventional kerosene, which brings some aircraft fuel-efficiency advantages due to lower fuel burn and less fuel mass to board to achieve the same mission. Detailed analysis by the team is on-going.<\/p>\n\n\n\n<p>\u201cEngines and fuel systems can be tested on the ground but the only way to gather the full set of emissions data necessary for this programme to be successful is to fly an aircraft in real conditions,\u201d said Steven Le Moing, New Energy Programme Manager at Airbus. \u201cIn-flight testing of the A350 offers the advantage of characterising direct and indirect engine emissions, including particulates from behind an aircraft at high altitude.\u201d<\/p>\n\n\n\n<p>Simon Burr, Rolls-Royce Director of Product Development and Technology, Civil Aerospace, said: \u201cThis research adds to tests we\u2019ve already carried out on our engines, both on the ground and in the air, which have found no engineering obstacle to our engines running on 100% SAF. If we are to truly decarbonise long-haul air travel, then 100% SAF is a critical element and we are committed to supporting its certification for service.\u201d<\/p>\n\n\n\n<p>The DLR Falcon chaser aircraft is equipped with multiple probes to measure emissions at cruise level down to a distance of only 100 metres from the A350 and feed them into scientific instrumentation for analysis.<\/p>\n\n\n\n<p>\u201cSAF has been shown to have a significantly lower carbon footprint over its life cycle compared to conventional jet fuel and now we are seeing it is advantageous in reducing non-CO2 effects too,\u201d said Markus Fischer, DLR\u2019s Divisional Board Member for Aeronautics. \u201cTests such as these are continuing to develop our understanding of 100% SAF, its use in flight and we are seeing positive signs for its potential in climate mitigation. We look forward to studying the data from the second series of ECLIF3 flights, which restarted with a first chase flight above the Mediterranean earlier this month.&#8221;<\/p>\n\n\n\n<p>In 2015, DLR performed the ECLIF1 campaign, investigating alternative fuels with its Falcon and A320 ATRA research aircraft. These investigations continued in 2018 with the ECLIF2 campaign which saw the A320 ATRA flying with a mixture of standard jet fuel and up to 50% HEFA. This research showed the advantageous emission performance of fuel mixtures up to 50% SAF and paved the way for the 100% SAF test flights for ECLIF3.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related
