The Water-Enhanced Turbofan as Enabler for Climate-Neutral Aviation

open access: yesApplied Sciences, 2022
A significant part of the current aviation climate impact is caused by non-carbon-dioxide emissions, mainly nitrogen oxides (NOx) and contrails. It is, therefore, important to have a holistic view on climate metrics.
