PACIFIC project to assess impact of non-CO2 emissions from aviation
Airbus has launched PACIFIC, a project that will assess the impact of aviation's non-CO2 emissions on local air quality and climate and ways to mitigate contrails.
Studies have found that Sustainable Aviation Fuels (SAF) could reduce soot particles and contrail ice crystals, but additional information on fuel composition and its processing in the engine is necessary to better understand the effects and benefits of SAF.
Along with a consortium of 10 European partners, PACIFIC (Particle emissions, Air Quality and Climate Impact related to Fuel Composition and Engine Cycle) aims to bridge the gap in understanding aviation's non-CO2 emissions by testing a range of fuels under controlled conditions.
The project is expected to ensure consistency in combustion parameters and hardware similarity from lab-scale experiments at the German Aerospace Center (DLR) to full aircraft engine tests at Airbus Toulouse.
The research will focus on understanding how soot forms during fuel combustion, using improved prediction tools to better anticipate its presence in engine emissions. It will also analyse the quantity of fine particles released at different engine power levels, refining methods to estimate their impact from ground tests to real flight conditions.
