The results will support future fuel specifications and policy recommendations to minimise environmental impact of aviation.​

The research will focus on:​

• Improving prediction and modelling ability at altitude establishing a validation chain from low TRL single sector testing over triple sector test at full cruise condition to engine under-wing tests​
• Quantity of total particulate matter at different engine power settings refining methods to estimate their impact from ground tests to real flight conditions​
• Characterising the sooting propensity of individual fuel compounds as well as from the fuels used in the project
• Assessing how these particles contribute to ice crystal formation, a major factor in contrail development, using advanced measurement techniques​
• Evaluating the broader climate effects of these emissions by examining how different fuel compositions and engine settings influence contrail formation and properties, and their impact on global warming.

 

The first analyse result will be available on second half of 2026.
