This project received funding from the European Union’s Horizon 2020 research and innovation programme under grant  agreement No 860103.

ENODISE focused on future, disruptive civil air transport concepts and has been designed to develop the knowledge, data, tools and methods that are necessary to understand, model and optimize engine-airframe aerodynamic and acoustic installation effects, with a strong focus on innovative architectures bringing a tighter integration of the propulsive system with the wing, fuselage or control surfaces. Simplified geometrical configurations have been investigated with the aim to unravel the intricate aeroacoustics mechanisms involved in future aircraft architectures, and eventually enable their reliable simulation and optimization while mitigating the adverse effects.

The project’s objectives were the following:

- the development of a novel research approach, based on extensive test campaigns complemented with numerical simulations, permitting to understand the aerodynamic and aeroacoustic installation effects in novel propulsion integration concepts;

- to perform numerical optimization studies in clean vs. installed conditions, and to validate the results quantitatively through experimental verification;

- the inclusion of innovative flow and acoustic control technologies in the optimization loop;

- the constitution of extensive, well documented and cross-validated experimental and numerical databases that will be made publicly available for benchmarking purposes. 

 

The ENODISE project has delivered significant advancements in airframe-propulsion integration, pushing forward innovative solutions to improve aircraft efficiency while minimizing noise and environmental impact. The project developed and validated new numerical and optimization frameworks, advanced experimental methodologies, and novel noise mitigation strategies, with the results widely disseminated to benefit both the aerospace industry and other sectors.

 

One of the key achievements was the development of highly accurate multi-fidelity numerical models, which have improved the ability to predict aeroacoustic behavior and optimize propulsion-airframe integration. These models have been incorporated into industrial design workflows, allowing manufacturers to develop quieter and more efficient aircraft. Additionally, the ENODISE project conducted extensive wind tunnel experiments across multiple facilities, producing a validated dataset that is now publicly available for researchers and industry professionals.

 

Noise reduction strategies explored in ENODISE are directly applicable to various industries beyond aviation. Wind energy companies can leverage insights on blade aerodynamics to reduce noise from turbines, automotive manufacturers can adopt new low-noise fan designs for electric vehicles, and UAV developers are integrating quieter propeller technologies to minimize disturbance in urban environments. The project’s research has also informed best practice guidelines, helping engineers design propulsion systems that optimize both aerodynamic performance and noise reduction.

 

To ensure broad accessibility and long-term impact, ENODISE has pursued a comprehensive dissemination strategy. The results have been published in over 30 peer-reviewed papers and presented at major international conferences. Open-access datasets have been made available via ZENODO, and a dedicated online tool has been developed to help users navigate and extract insights from the project’s extensive experimental and numerical databases. Furthermore, a white paper outlining roadmaps for future disruptive aircraft architectures has been distributed to policymakers, industry leaders, and regulatory bodies, helping shape the future direction of sustainable aviation.
