September 4, 2025 (Full application, single-stage)

€15,000,000 total; 1 project funded; single lump sum grant; project duration typically 36–48 months

Supports development of advanced testing capabilities in strategic EU wind tunnels for next-generation, climate-neutral aviation technologies.

--- ## Description This Horizon Europe Research and Innovation Action funds the development and advancement of new and adapted testing capabilities in strategic European wind tunnels, with a focus on enabling next-generation, climate-neutral aviation. Projects should target critical technologies such as airframe-propulsion integration, high aspect ratio and highly flexible unfuelled wings, distributed hybrid/electric propulsion, advanced aeroacoustics, and experimental simulation for novel low-emission aircraft. The grant aims to foster innovations in experimental setups, instrumentation, testing procedures, and digital tools, aligning with the Clean Aviation Strategic Research and Innovation Agenda and the Fly the Green Deal vision. Projects are encouraged to leverage synergies with other EU and national initiatives and to facilitate collaboration between multiple testing facilities, ensuring agreed interfaces and data formats to address the complexity of multidisciplinary aircraft design and validation. --- ## Due Dates - September 4, 2025: Full application deadline (single-stage, 17:00 Brussels time) --- ## Funding Amount - Total budget: €15,000,000 - Indicative number of grants: 1 (single project will be funded) - Funding is provided as a lump sum grant covering all eligible costs - Typical project duration: 36–48 months (final duration to be proposed in application) - Funding rate: 100% of eligible costs --- ## Eligibility - **Type of action:** Horizon Europe Research and Innovation Action (RIA), lump sum funding - **Consortium requirements:** Minimum three independent legal entities, each established in a different EU Member State or Associated Country;
