Horizon Ultraefficient Aircraft Noise Reduction

Funds two €2.5M research projects to reduce cabin, engine and community noise from new ultraefficient aircraft designs.

ScheduledEuropean CommissionEU

New ultraefficient aircraft architectures can reduce energy use while creating difficult airframe, cabin and propulsion noise problems. This two-stage Research and Innovation Action funds two projects to improve the evidence and methods used to predict and reduce those noise sources.

Projects should develop advanced numerical and experimental aero-acoustic methodologies for large passenger aircra

Developing and validating numerical and experimental aero-acoustic methods for new ultraefficient aircraft, especially large passenger aircraft using open-fan or ultra-high-bypass architectures. Projects should address airframe and cabin noise, engine sources and installation effects, noise perception and annoyance, experimental data, multidisciplinary aerodynamic and aeroacoustic optimisation, and integrated metamaterials or structures for noise reduction.
