The new test campaign for the detailed investigation of particle and gas emissions using sustainable aviation fuels (SAF) started on 17 July. The test object is the Allison 250 C20B engine used in small aircraft and helicopters. The test campaign focuses on the analysis of soot particles in composition and size distribution as well as the analysis of various volatile organic compounds (VOC).
A direct comparison will be made between conventional fuels, various blends of SAF and 100% SAF. The project is supported by Munich Aerospace (TUM and UniBW) and Neste. The test setup is shown in the following figure.
