CLAIM · Clean Aviation Support for Impact Monitoring

The CLAIM proposal main high-level objectives are:1. To obtain an answer on how to best translate the Clean Aviation Programme objective to reduce net greenhouse gas emissions by -30% versus state of the art into tangible metrics in terms of measurable engine tailpipe emissions, bya. Collecting, analysing and establishing the current level of scientific understanding within the worldwide community of climatology and atmospheric sciences, and of aviation climate impact and its greenhouse gas emissions contributions;b. Identifying knowledge gaps, barriers, and needs for research in view of orienting more appropriately the technology research streams for future green and zero-emission aircraft.2. To compile an inventory of relevant aeronautical advanced research activities and technology areas, not only from the aviation community but potentially also from other sectors if relevant bya. Reviewing and analysing aeronautical literature on disruptive aircraft concepts or greener aircraft as well as on climate-neutral aviation in general, including their (preliminary) environmental performance/results;b. Proposing a way forward and an approach that highlights the assumptions and metrics used to reconcile the numbers and the prospects of performance improvements for the main technologies;c. Categorising these concepts in terms of aerodynamics, structural, systems and propulsion technologies and their associated benefits at aircraft level, as well as performing a technology mapping;d. Performing a preliminary performance assessment using proposed assumptions and criteria for an SMR and an HER.Consequently, through achieving its objectives, the CLAIM proposal assists Clean Aviation, EC and EASA by providing more clarity and contributing to all of the expected outcomes
