Description

Expected Outcome:

Project results are expected to contribute to both of the following expected outcomes:

• Additive manufacturing including high performance polymers, composites and metals, offering significantly improved performance compared to state-of-the-art. Entire process including design / manufacturing / characterization and testing / certification.

• Sustainable aircraft circular design and manufacturing processes of individual high-value components towards further developing the innovation pipeline from system demonstration to deployment stage in the EU and Associated Countries.

Scope:

This topic focuses on:

• Additive design and manufacturing of aircraft and engine structural components have already transformed the industry and are expected to be the key to the EU competitiveness. Geopolitical aspects for raw materials reinforce the importance of additive manufacturing, while the European RTOs and industry recognised that there is a substantial untapped potential towards even higher energy efficiency, savings in critical raw materials and higher quality parts. The main objective of this topic is to resolve existing challenges in the AD/AM of metal, high performance/value polymer and composite parts, related to residual stresses, non-equilibrium phase transformations, joining, defects and reproducibility among others.

• Building on previous research efforts (i.e. H2020-SUSTAINair) and EREA’s Future Sky initiatives on circular aviation, proposals should focus to real, challenging and competitive industrial use cases for circular design of individual components, joining technologies, improved maintenance and repair technologies to extend aircraft lifetime and improved recovery of high-quality recycling materials. Especially as regards engines and safety critical systems, real-time condition monitoring and inspection methods have the potential to improve repairability by determining an optimized degradation status, allowing smart repairs on-wing and on-site that reduce or postpone the need for material- and energy-intense overhauls or replacements.

Conditions5

Typed facts extracted from the source documents by Scindu's grant-data review. Each value keeps its own conditions. Unknown means unstated, not zero or unlimited.

Applicant type
Unless the call/topic provides otherwise, consortium beneficiaries must include at least three independent legal entities established in different countries: one in an EU Member State and two others in different EU Member States or Associated Countries. No topic-specific consortium-size exception was identified in this reviewed topic section.
Application restriction
The MOBILITY call is scheduled to open 15 December 2026 and close 14 April 2027; the Work Programme states deadlines are 17:00 Brussels local time. This call window is scheduled, not evidence that applications are currently accepted.
Consortium required
Yes
Eligible project scope
Research and innovation for sustainable aircraft circular design and additive manufacturing; the topic addresses high-performance polymers, composites and metals, and industrial use cases for aircraft and engine structural components. No job titles or pay rates are specified by the topic.
Other condition
The call overview indicates around 2 project(s) expected to be funded for this topic. This is a planning estimate, not guaranteed awards or a binding consortium/project-count condition.
Amounts and costs7
Indicative budget
€5,000,000

Topic budget as stated in the portal's budget table. Lump-sum and per-project limits are in the call conditions.

Call allocation
€131,000,000

Overall indicative CL5-2027-03 call-pool budget, not a per-project or per-beneficiary award; subject to availability of EU appropriations.

Eligible cost
If a project uses satellite-based Earth observation, positioning, navigation and/or related timing data/services, beneficiaries must use Copernicus and/or Galileo/EGNOS; other data/services may also be used.
Eligible cost
Personnel may be included as estimated cost categories in the lump-sum proposal budget, not separately reimbursed as actual payroll. Cost estimates must approximate actual costs, follow beneficiaries’ normal practices, be reasonable/non-excessive, align with proposed activities, and satisfy Horizon Europe basic eligibility rules.
Eligible cost
Eligible costs are funded as a lump sum. Under the Lump Sum MGA, contributions are eligible only when amounts are set out in Annex 2, work packages are completed, and work is properly implemented/results achieved in accordance with Annex 1 during the action period. This is payment by completed work package, not actual-cost reimbursement.
Funding intensity, maximum
100 percent_of_eligible_costs

Maximum Horizon Europe funding rate for this action type is 100% under General Annex G; the topic does not state a different rate. For lump-sum/unit grants, the rate is applied through the amount-setting methodology.

Expected contribution per project
€2,500,000

Commission estimate of EU contribution per project; not a fixed ceiling or floor, and different requested amounts are not precluded.

Topic allocation
€5,000,000

Indicative topic budget pool. It is distinct from the per-project expected contribution and is not an individual beneficiary award.
