Sustainable Aviation NLR and Partners Research Roland Vercammen Roland Vercammen Nationaal Lucht- en Ruim tevaartlaboratorium – National Aerospace Laboratory NLR Various reasons for sustainable aviation � W orldw ide attention for clim ate change im pact � Fossil fuel is lim ited � Cost reduction due to fuel efficient operations � Environm ental im pact around airports � Acceptance and trust of surrounding com m unities 1
European goals for sustainable aviation Vision 2 0 2 0 / ACARE goals � 50% reduction in CO2 per passenger kilometer � 50% reduction in perceived noise per flight � 80% reduction in NOx � Minimise the industries impact on the p global environment Exam ple: 5 0 % CO2 reduction Expected contribution by innovation of: � Aircraft: 2 0 -2 5 % � Engine: 1 5 -2 0 % � ATM: 5 -1 0 % 2
