The purpose of the COMPANION project is to define, design and prepare a common flight test demonstrator platform to enable the validation of ultra-efficient propulsion systems developed in Clean Aviation Call#01 projects at full scale and in a wide envelope of realistic operational conditions. Given the clear requirement in the roadmap planning of the CA projects OFELIA and SWITCH for flight test demonstrations in Clean Aviation Phase 2 to achieve TRL 6 before the end of the program in 2030, a corresponding platform must be prepared to be available before the end of year 2026. The project targets to prepare and deliver the hardware of the flight test platform ready for engine installation by the end of June 2026. The flight clearance process will be opened in COMPANION, but will need to continue with the installation of the demonstrator engines in follow-up projects to be defined at the end of CA Phase 1. The project plan proposes to prepare a common flight test demonstrator platform on the basis of an Airbus A380 aircraft with one of the inboard engine pylons modified to accommodate versatile ultra-efficient proposal systems which are currently under development for a Clean Aviation Short Range and Short and Medium Range concept aircraft, namely an Open Rotor test engine and a hybrid electric Ultra High ByPass Turbofan. The flight test aircraft will be fully equipped to host a diversity of standard and special flight test instrumentation that will be defined in close cooperation with the projects OFELIA and SWITCH to provide all data required to quantify the performance of the demonstrator engines under operational conditions. The test aircraft allows the demonstrator engines to operate on conventional kerosene and SAF fuel at blending rates of up to 100%.

FUTPRINT50 addresses the need to accelerate disruptive technologies in aviation to ensure Carbon Neutral growth commitment from FlightPath2050. It will develop tools, technologies and aircraft level analysis for key hybrid-electric technologies supporting the entry into service of a 50 seat class aircraft by 2035/2040. This type is at the locus of convergence of timeframe and technology, promising to open with improved costs new routes for point 2 point connection of smaller, interior cities and villages at lower infrastructure costs than rail or road transportation, fulfilling aviation’s higher goal of connecting people for the creation of wealth and societal good. FUTPRINT50 will focus on energy storage, energy harvesting and thermal management. Besides advancing the state of the art of these technologies, it will research and develop MDO design methodologies whilst considering uncertainty, models and tools to evaluate new configurations and integration at system and aircraft level. To attain the ambitious vision of an entry into service aircraft by 2035/2040, FUTPRINT50 will develop roadmaps to align future research on technology development but also the regulatory side, striving for market, technology and legal readiness for entry into service. For this FUTPRINT50 will use research developed within the project but also extend itself to other complementary projects and initiatives, besides engaging the main stakeholders in comprehensive workshops. Furthermore, open-source aircraft design tools, hybrid-electric aircraft designs, and reference data sets will be generated and shared openly with the community to accelerate the development of future hybrid-electric aircraft. Finally, FUTPRINT50 will be developed by an international consortium of diverse and highly competent partners, abridging the EU with USA and Brazil and supported by an Advisory Board including EASA and ensuring connection with Canada.

In many respects, the evolution of the Japanese airline passenger represents an anticipation of the societal trends for the world's future airline passenger (ageing and being connected from point to point for instance). If the design of the future human-centered passenger cabin is able to satisfy the highly demanding expectations from the Japanese customer (in terms of safety, perceived quality, comfort, connectivity), it will also most likely please the customers in Asia and elsewhere in the world. The objective of the FUCAM project (FUture Cabin for the Asian Market) is thus to develop a 2025+ conceptual cabin design devoted to the Asian market, for short and medium range aircraft. The FUCAM project will analyze the user requirements from the airlines and passengers in Japan and two other key markets representative of the Asian area (China, South-East Asia). In parallel, the project will establish a panorama of the innovative cabin technologies emerging in Europe and Japan. From these inputs, it will compose a cabin concept capable of answering the collected requirements, while incorporating the most promising enabling technologies. Furthermore, thorough studies will be conducted on the integration of this cabin concept into the aircraft (installation, reconfiguration, power and data compatibility), in order to raise its maturity level to TRL3. This will include several validation steps, involving first a functional mockup produced in Europe and later a full-scale customer validation mockup produced in Japan. FUCAM is a 3-year collaborative project with Japan comprising 8 research and industrial partners from 7 European countries.

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, by a. 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 by a. 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
