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 aim of the AERO-UA project is to stimulate aviation research collaboration between the EU and Ukraine through strategic and targeted support. AERO-UA is focused solely on Ukraine, because the country has a huge aerospace potential but a low level of aviation research collaboration with the EU. Ukraine’s aerospace sector spans the full spectrum of systems and components development and production with OEMs, Tier 1 and 2 suppliers, aeroengine manufacturers, control systems manufacturers, R&D institutions, aeronautic universities, and SMEs. This is also reflected in the sector's important contributor to the country’s economy (e.g. aircraft production of €1,9 billion in 2011). Ukrainian aerospace organisations possess unique know-how that can help Europe address the challenges identified in the ACARE SRIA / Flightpath 2050 Report. Furthermore, following the signing of the Agreement for the Association of Ukraine to Horizon 2020 in March 2015, Ukrainian organisations are eligible to participate in Clean Sky 2 and H2020 Transport on the same funding terms as those from EU member states. Equally, genuine commercial opportunities exist for European aviation organisations to help modernise Ukraine’s aerospace sector. The AERO-UA project will achieve its overall aim via four high-level objectives: 1. Identifying the barriers to increased EU-UA aviation research collaboration; 2. Providing strategic support to EU-UA aviation research collaboration; 3. Supporting EU-UA aviation research knowledge transfer pilot projects; and 4. Organising awareness-raising and networking between EU-UA stakeholders. The AERO-UA consortium is comprised of key EU and UA aviation organisations that will implement WPs closely mapped to the high-level objectives. The consortium will be supported by an Advisory Board involving Airbus, DLR, Min. Education and Science of Ukraine, Ukrainian State Air Traffic Services Enterprise and retired Director of EADS Jean-Pierre Barthélemy.
