Noise reduction breakthroughs for new ultraefficient aircraft

Opens 15 Dec 2026

The EU's Horizon Europe programme expects to make 2 awards of €2.5 million each, from a total budget of €5 million. Applications close on 14 Apr 2027 (EU calls usually close at 17:00 Brussels time). Organisations in EU member states and Horizon Europe associated countries such as Türkiye can usually take part; the topic conditions control.

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.

Who can apply

Consortium of at least 3 independent legal entities from 3 different EU Member States or associated countries, at least one in a Member State (Horizon Europe standard rule).

Applicant categories are a starting point. The official call decides eligibility.

Timing

Two-stage call. Next deadline 2027-04-14; later stage/cut-off 2027-10-07. The portal states the exact cut-off time (EU calls usually close at 17:00 Brussels time).

How to apply

1. Read the full topic on the Funding & Tenders Portal: expected outcome, scope, type of action and the topic conditions, including any country restrictions.
2. Register each participating organisation in the Funding & Tenders Portal to get a PIC.
3. Consortium of at least 3 independent legal entities from 3 different EU Member States or associated countries (Horizon Europe standard rule; Türkiye is associated). Confirm in the topic conditions.
4. Prepare Part A (administrative forms and budget, completed in the portal) and Part B (the technical description on the official template for this type of action).
5. Submit in the portal before the cut-off time on the deadline day. Late submissions are not accepted.
