What is the Next generation testing capabilities in strategic EU wind tunnels Call?
Expected Outcomes
• Airframe-transformative technologies, including integrated airframe–propulsion configurations.
• High aspect-ratio and/or highly flexible unfuelled wings (e.g., for liquid hydrogen aircraft).
• Distributed hybrid/electric propulsion concepts and demonstrators.
• Improved understanding and mitigation of airframe and propulsion aeroacoustics.
• Further advancements in experimental simulation capabilities to accelerate development of novel low-emission aircraft and reduce lead times.
Scope Requirements
• Focus on strengthening and updating EU strategic testing capabilities (wind tunnels, propulsion rigs) only—no funding for buildings, civil works or auxiliary facilities.
• Align with the updated Clean Aviation Strategic Research and Innovation Agenda and Flightpath 2050 climate-neutral aviation goals.
• Address one or more of the following priority areas:
– Airframe-transformative technologies and integrated airframe-propulsion concepts;
– High aspect-ratio and/or highly flexible unfuelled wings;
– Distributed hybrid/electric propulsion systems;
– Boundary layer ingestion and ground-effect aircraft architectures;
– Airframe and propulsion aeroacoustics;
– Advanced experimental simulation capabilities to shorten development lead times.
• Exploit synergies with existing EU (e.g., RINGO, Clean Aviation) and national projects where relevant.
• Where multiple testing facilities participate, establish and agree on common technical interfaces, data exchange formats and system architectures.
Special Conditions
• Admissibility: Proposal page limits and layout as per Annex A and E of the Work Programme General Annexes and Part B of the application form.
• Eligibility: Participating entities must be from countries listed in Annex B; non-associated third countries only if funding provisions exist.
• Financial & operational capacity, exclusion criteria: per Annex C of the Work Programme General Annexes.
• Evaluation & award: Criteria, scoring, thresholds (Annex D); processes and timelines (Annex F).
• Funding model: Lump-sum contributions as defined in the 7 July 2021 Decision; eligible costs and simplified cost rules per Annex G.
• Use of application, evaluation and MGA templates specific to Horizon RIA and lump-sum grants.
• No specific conditions beyond general model grant agreement requirements.
