Wing concepts and architecture:
Three wing concept configurations have been analysed and evaluated in the first part of the project: Strut Braced high aspect ratio Wing (SBW), Cantilever high aspect ratio wing (CNT) and Distributed propulsion wing.
In 2025 an amendment of the Grant Agreement was prepared in order to align the activities to the new Ultra Efficient Regional Aircraft (UERA) use case. This configuration corresponds to a twin-engine cantilever wing and is being developed in parallel with the distributed propulsion cantilever wing (DPW).
The wing model v1 of the DPW wing is already finished. Additionally, an aspect ratio trade-off is on-going and will be reported in the wing model v2.
Demonstrators:
Manufacturing activities are running at full pace. Multiple components of the different demonstrators are already available and, in some cases, the demonstrators are already fully assembled and being instrumented to start the testing phase:
Different components of the flap demonstrator have been already manufactured and the demonstrators for the integrated fuel vent system are completed.
Structural health monitoring system has been installed in the thermoplastic in-situ consolidated shear panel.
Manufacturing and installation of the Sustainable Aviation Fuel Integration test bench is completed.
Final assembly and laboratory test of the complete servo-actuated morphing aileron on a fixed rig is completed
Technology maturation:
The majority of technologies have passed Technical Readiness Level TRL4 in 2025.
Related to wing anti-ice protection, only the resistive ice protection system tests were successful in the wind tunnel. A new test campaign is being prepared to test again the induction ice protection system in 2026.
Impact detection Structural Health Monitoring achieved TRL5 in 2025.
Thermoplastic in-situ consolidation outer wing lower cover and liquid resin infusion centre wing upper cover have been successfully manufactured thus demonstrating the maturity of both technologies.
Results assessment:
In terms of Ecodesign, the preliminary Life Cycle Assessment prepared in 2024 is being completed with the data obtained during the manufacturing of the demonstrators and the Final Version of the assessment is planned for the end of September 2026.
Impact Monitoring yearly report has been approved by the Project Officer.
Structural Health Monitoring, Leading Edge (LE) Technologies, Liquid Resin Infusion (LRI) Integrated Primary Structure, Ice Protection System and Integrated Fuel Vent System technologies have been presented to EASA. The written feedback received from EASA has been used to populate the Certification Roadmap for Structural Health Monitoring, LE Technologies and LRI Integrated Primary Structure.
