In response to the public consultation on Clean Aviation Partnership: A short comment on ultra-efficient gas turbines and sustainable aviation fuels
Other, 2020

This two-page comment on the Clean Aviation SRIA, contains output from two Horizon 2020 projects, ULTIMATE (ultra-efficient engines) and ENABLEH2 (hydrogen aircraft). The report has also been updated by a coordinated effort on collecting strategic inputs from Chalmers University of Technology. Some output from efforts on road-mapping conducted together with leading aero engine manufacturers is also supporting this comment. The comment concentrates on giving input on the two key thrusts “3. Ultra-efficient Aircraft and Gas Turbines” and “4. Sustainable Aviation Fuels enabled Aircraft”. However, for all four thrust areas, it is noted that as aircraft design complexity increases the need for dynamic modelling, energy management and optimal control increases.
