The EFACA project consists of 6 main objectives at 3 levels. Level 1 consists of three TRL3 demonstrations of technologies relevant to the greening of aviation: (WP1) bench testing of a gearbox combining input from gas turbine and electric motor for an hybrid turbo-electric propulsion system for a propeller-driven regional aircraft; (WP2) comparative testing of fuel cells with conventional liquid and novel phase cooling, to show the benefits up to 20% of the latter in higher net power, reduced heat losses, and smaller volume and weight also reengineering of fuel cell and structural components to increase power-to-weight ratio up to 80%; (WP3) static ground testing of a complete liquid hydrogen fuel system from cryogenic tank to vaporization and combustion in a wide range of operating regimes and simulation of application to the speed and altitude flight envelope of jet airliners. Level 2 consists of two preliminary designs: (WP7) an 80-seat 1000-km range regional propeller driven aircraft including design and integration of hybrid turbo-electric propulsion; (WP89) a 150-seat 2000-km range jet liner with liquid hydrogen fuel including design and integration of cryogenic tanks and fuel system. At level 3 a road map (WP10) for the achievement of the EU environmental targets for aviation synthetizing conclusions in four steps: (i) current status on (WP4) emissions and (WP5) noise versus future targets and gap to be covered; (ii) assessment of relevant technologies to cover the gaps, including (WP6) battery electric and (WP9) sustainable aviation fuels, besides hydrogen (WP7) fuel cells and (WP8) turbines; (iii) most suitable technology for each class of aircraft (light, small and medium regional, single and twin aisle jetliners), and maturation time of the technology; (iv) contribution of each aircraft class to CO2 and non- CO2 global and local emissions and noise, leading to (WP10) a comprehensive road map of actions for carbon-free or emissions-free flight.

The AREANA project addresses the call for "Aviation research synergies between Horizon Europe, AZEA and National programs" by providing advanced novel approaches to foster the European aviation research ecosystem. It encompasses three interconnected, yet thematically distinct parts. Firstly, approaches improving on the coordination of aviation funding programs will be addressed by coordinating and supporting synergies between European, National, and Regional R&I aviation programs. The project aims to facilitate joint calls or other co-funding mechanisms that align EU, National, and Regional activities in specific fields and accelerate the update and sharing of aviation technology infrastructures in the European Research Area. Secondly, the upcoming Aerodays will be prepared. The consortium suggests them to take place during the first half of 2025 in Warsaw, Poland. They would then coincide with the Polish presidency of the Council of the European Union. Thirdly, AZEA (Alliance for Zero Emission Aviation) activities will be supported by conducting mappings and analysis, including the identification of potential technological and administrative gaps and lack of related R&I and standardization efforts, removing the obstacles for zero-emission aviation. Close cooperation with the Advisory Council for Aviation Research and Innovation in Europe (ACARE) and other institutions is expected. The AREANA project will help to sustain and foster the European aviation research ecosystem, thus helping to achieve the environmental goals while ensuring European competitiveness. This will be achieved by connecting and aligning different funding mechanisms, bringing together aviation stakeholders during the Aerodays and supporting the Alliance for Zero Emission Aviation.

The overall objective of PARE (Perspectives for the Aeronautical Research in Europe) is to trigger collaboration between European stakeholders to support the achievement of the Flightpath 2050 goals, by providing yearly reports (and respective methodology) that assess the progress, gaps and barriers and propose suitable measures to close the remaining gap. The main outputs of PARE are three yearly reports on the “Perspectives for Aerospace Research in Europe” that use specific benchmarks to assess the progress towards each of the 23 Flightpath goals and the gap remaining. The assessment includes EU projects (Clean Sky, SESAR and others), national projects, academic and industrial research reports. Aspects like long-distance travelling and relevant emerging technologies from non-aeronautical sectors are focused, as well as greater participation from recent EU member states (e.g. in Eastern Europe) and associated countries (e.g Ukraine). The activities of Europe’s competitors (e.g. the U.S.) are also considered in PARE to assess: areas of EU leadership to be exploited; areas requiring specific effort in the EU to catch-up; areas of common interest for cooperation. PARE will contribute to fulfil the “Mobility for Growth” workprogramme with an assessment of progress in aerospace research, gaps and bottlenecks. The comprehensive yearly report (RC), can originate a public version (RP) and specific versions for academy and research (RA), industry, airlines and airports (RB) and certification authorities, international and professional associations (RC). The wide dissemination of each report will allow to collect feedback to improve the next one thus establishing the final reporting procedure that could be extended beyond the end of the project. Also addressed is the attraction of young talent and the increase in the participation of woman in aerospace including the preparation of a newsletter on exciting and attractive developments in aeronautics.
