Description
Expected Outcome:
Project results are expected to contribute to all of the following expected outcomes:
• Airframe / cabin noise for new aircraft design;
• Engine noise sources and installation effects;
• Noise perception/annoyance and mitigation methodologies.
Scope:
The topic aims to deliver advanced and validated numerical and experimental aero-acoustic methodologies for the noise prediction of new ultraefficient aircraft designs, primarily for large passenger aircraft with new open fan engine architectures and ultra-high by-pass ratio architectures.
The topic should reinforce fundamental understanding, fill gaps and propose new/updated technologies towards enabling open fan designs and techno bricks for significantly reduced cabin noise. Mayor emphasis is expected to be put to existing/new experimental data and procedures, multi-disciplinary design and optimisation, aerodynamics, aeroacoustics and noise reduction integrated metamaterials/structures.
In addition, the proposals may also provide even better noise footprint assessments and better annoyance understanding and mitigation methodologies.
The topic should build upon lessons learnt and gaps identified from H2020.CS2-LPA-01-D01 as well as complementing the projects resulted from HORIZON-CL5-2022-D5-01-12.

Conditions
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.
- Consortium requiredBeneficiaries; affiliated entities do not count
- Yes
Unless topic-specific text says otherwise, three independent beneficiaries from three countries: at least one Member State and two others from different Member States or Associated Countries.
- Consortium required
- Yes
Unless the exact topic-specific conditions provide otherwise, this action requires three independent beneficiary legal entities established in three different countries: at least one in an EU Member State and at least two others in different EU Member States or Associated Countries. Affiliated entities do not count toward the minimum. Topic-specific required organisation types, applicant restrictions, and exceptions recorded elsewhere in this packet remain applicable; this baseline does not replace them.
- Other condition
- The Work Programme classifies this topic as a Research and Innovation Action.
- Other condition
- Under the destination rules, legal entities established in China are not eligible to participate in RIAs and IAs falling under this destination, subject to the referenced General Annex B rules.
- Other condition
- Project results are expected to contribute to airframe/cabin noise reduction, engine noise-source/installation-effect reduction, and noise-perception/annoyance and mitigation methods.
- Other condition
- Call overview lists around EUR 2,500,000 per project and around 2 expected project(s); both are indicative and do not guarantee an award or set a recipient cap.
- Other condition
- For a Type 2 detailed-budget lump sum, the guide requires per-beneficiary/affiliated-entity and per-work-package estimates by cost category; estimates must follow normal practices, be reasonable and non-excessive, and be necessary for the proposed activities.
The source identifies lump-sum form but not a specific subtype; Type 2 guidance is conditional and is not proof this call uses a Type 2 detailed budget.
- Other condition
- The granting authority may, up to four years after the action ends, object to transfer of results ownership or exclusive licensing under the specific Annex 5 provision.
- Other condition
- If satellite-based Earth-observation, positioning, navigation or related timing data/services are used, beneficiaries must use Copernicus and/or Galileo/EGNOS; other services may additionally be used.
- Other condition
- Develop advanced validated numerical and experimental aero-acoustic methodologies to predict noise for new ultraefficient aircraft, primarily large passenger aircraft with open-fan or ultra-high-bypass architectures. Reinforce fundamental understanding and fill gaps; develop/validate technologies for open-fan designs and lower cabin noise; emphasize experimental data/procedures and multidisciplinary design/optimization, aerodynamics, aeroacoustics and noise-reduction integrated metamaterials/structures. Noise-footprint assessment and annoyance/mitigation work may also be proposed. Build on identified prior EU project lessons/gaps as stated in the topic.
- Other condition
- Applicants submit an outline application first; successful applicants are invited to submit a full second-stage application. First-stage evaluation covers Excellence and Impact; the second stage uses the full criteria set.
- Other condition
- The Director-General may open the call up to one month before or after the envisaged opening date and may delay deadlines by up to two months; all deadlines are at 17:00:00 Brussels local time.
Amounts and costs
- 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.
- Eligible cost limit
- 25 percent flat rate of eligible direct costs, subject to the base exclusions in conditions
Horizon Europe General Annex G describes a 25% indirect-cost flat rate on eligible direct costs, excluding eligible direct subcontracting costs, financial support to third parties, and any unit costs or lump sums that include indirect costs. For HORIZON-AG actual-cost grants this is a cost-calculation rule, not a grant-rate increase. For HORIZON-AG-LS it informs the underlying eligible-cost estimate only; it is not an additional payment on top of the fixed lump sum. The topic indicative allocation and per-project contribution are distinct from this cost rate.
- Eligible cost limitMGA eligible direct cost categories A–D subject to exclusions
- 25 percent of eligible direct costs
This is an underlying cost rule for the lump-sum model, not a separate cash reimbursement; excluded cost categories and operating-grant condition apply.
- Funding intensity, maximumResearch and Innovation Action beneficiaries under this action
- 100 percent of eligible costs per beneficiary
Maximum funding rate under General Annex G; it is not an award guarantee. For the lump-sum model the rate is applied through amount-setting methodology, not separate payroll reimbursement.
- Funding intensity, maximum
- 100 percent of eligible costs (general Research and Innovation Action maximum)
The exact Work Programme labels this topic a Research and Innovation Action. General Annex G gives RIA a 100% maximum; no separate topic rate was identified in this topic’s Specific conditions. This is not a guarantee or the topic-level indicative EU contribution; the final rate is fixed in the grant agreement. For this lump-sum topic, the rate is already applied in the methodology and is not an extra multiplier.
- Expected contribution per projectCommission estimate for this specific topic; no minimum/maximum cap
- €2,500,000
Work Programme expressly allows different amounts; the estimate is not a minimum, maximum or guarantee.
- Topic allocationTopic-level budget allocation; not per-project award amount
- €5,000,000
Indicative budget is subject to EU appropriations and is not an award guarantee.
Personnel and services
Other role
Staff cost the grant can fund
Underlying cost-estimate category only if permitted in the applicable lump-sum model; not a named position, vacancy, guaranteed headcount or salary entitlement. The grant amount is not separate actual-payroll reimbursement. MGA A.2/A.3 requires action assignment, employee-like working conditions, result ownership unless otherwise agreed, and rates based on actual incurred cost not significantly different from similar employees.
Other role
Staff cost the grant can fund
Underlying cost-estimate category only if permitted in the applicable lump-sum model; not a named position, vacancy, guaranteed headcount or salary entitlement. The grant amount is not separate actual-payroll reimbursement. MGA A.1 covers eligible employees assigned to the action and calculates salary costs under Article 6.2 A.1.
Other role
Staff cost the grant can fund
