OBERPFAFFENHOFEN, Germany - The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the German aircraft manufacturer Deutsche Aircraft have, for the first time, have tested both engines of DLR's D328 UpLift research aircraft powered by 100 percent synthetic fuel and carried out emission measurements on the ground. These were the first emission measurements in the world to be conducted on a turboprop aircraft powered by a synthetic, aromatic-free power-to-liquid (PtL) proxy fuel. Flight tests for in-flight emission measurements with DLR's D328 UpLift and Falcon 20E are scheduled for October, the German Aerospace Center (DLR) reports. Continue reading original article.
The Military & Aerospace Electronics take:
9 October 2024 - For the tests, a team from the DLR Institute of Combustion Technology in Stuttgart developed a probe, which was installed at Oberpfaffenhofen Airport to measure aircraft exhaust emissions during various thrust stages of the Landing and Take-Off (LTO) cycle. While the aircraft remained grounded, the probe collected exhaust samples and sent them to a mobile DLR laboratory located safely away from the plane. There, researchers analyzed the exhaust gas composition and particle characteristics. This method allowed for detailed analysis of engine load conditions on the ground, including the impact of different thrust settings on air quality. Researchers also studied how exhaust particles dispersed and aged over varying distances from the engine.
