The European Commission is funding a €329.5 million project to advance cabin acoustic optimization technologies for next-generation hybrid-electric regional aircraft. The initiative focuses on reducing cabin noise, improving passenger comfort, and validating lightweight, low-volume acoustic solutions under realistic conditions. Global entities are eligible to participate under Horizon Europe regulations.
Overview
The European Commission is supporting the development and demonstration of advanced cabin acoustic optimization technologies aimed at reducing noise in next-generation regional aircraft. This initiative targets the creation of innovative acoustic treatments, which enhance passenger comfort, improve aircraft performance, and align with sustainable aviation goals.
Key focus areas include:
- Innovative acoustic treatment solutions for cabin noise reduction.
- Ground demonstrations at Technology Readiness Level 5 (TRL5) in realistic noise and vibration environments.
- Lightweight, low-volume solutions compatible with ultra-efficient hybrid-electric regional aircraft.
Why Cabin Acoustic Optimization Matters
Noise reduction in aircraft cabins is essential for:
- Enhancing passenger comfort on regional flights.
- Supporting hybrid-electric propulsion concepts, which aim to reduce environmental impact.
- Improving aircraft operational efficiency without compromising design or weight.
The project ensures a balance between effective noise mitigation and space-efficient, lightweight solutions suitable for modern aircraft.
Who is Eligible?
The funding opportunity is open to a wide range of global participants:
- Legal entities from any country, including non-associated third countries.
- International organisations meeting the conditions of the Horizon Europe Regulation.
- Natural or legal persons recognized under national, EU, or international law, capable of exercising rights and obligations.
- Entities without legal personality may also participate if they can collaborate effectively on acoustic technology development.
How the Program Works
The initiative is structured to advance acoustic technology readiness and integration:
- Technology Development:
- Design and prototype innovative acoustic treatments.
- Focus on lightweight and low-volume materials suitable for hybrid-electric aircraft.
- Demonstration and Validation:
- Conduct ground demonstrations under representative noise and vibration environments (TRL5).
- Test effectiveness in real-world conditions to ensure readiness for aircraft integration.
- Integration into Aircraft Concepts:
- Solutions must be compatible with next-generation regional aircraft designs.
- Ensure that noise reduction does not compromise aircraft weight, volume, or efficiency.
- Collaboration and Funding:
- Total funding allocation: €329,500,000.
- Broad participation encourages international collaboration to accelerate technological advancement.
Tips and Common Mistakes
- Ensure your proposal clearly aligns with the TRL5 demonstration and hybrid-electric aircraft focus.
- Avoid submitting solutions that are too heavy or bulky, as weight and volume efficiency are critical.
- Include realistic performance validation metrics for noise reduction.
- Confirm eligibility criteria under Horizon Europe rules to avoid disqualification.
