Quiet Air Transport 

Achieving a Quiet Air Transport system in Europe is one of the key challenges addressed by Future Sky. Despite a constant progress in the development and introduction of modern aircraft with lower noise emissions, the constant growth of air traffic constitutes an increasing noise burden related to a rising annoyance in airports neighboring communities. As a consequence, international organisations such as the International Civil Aviation Organisation (ICAO), and the European Union through directives or regulations enforced severe noise-related regulations that may even imperil the traffic growth in Europe. With the design and manufacturing of low-noise aero-engines and aircrafts, the European aircraft industry addresses this issue which is certainly not limited to European communities. Innovative products raise the competitiveness of the European aircraft industry and drive the technology development in many others areas.

Therefore, the EREA decided to address the wider noise issues through three distinct research projects partaking to the Quiet Air Transport programme: ANIMA, ARTEM and RUMBLE. These projects complement several other research projects supported by the European Commission on aviation noise.



ANIMA means Aviation Noise Impact Management through Novel Approaches. It aims at better understanding the key factors that are influencing annoyance and how to cope with them. This is therefore a non-technological project which rather focuses on human beings and attitudinal factors. The rationale behind ANIMA is that besides lowering noise intensity – which certainly remains the primary objective of noise research – it is possible to relieve the noise burden of airports neighbouring communities by a suitable implementation of related regulations, by raising awareness through early information and involvement of communities ahead of the implementation of airport operations and procedures changes and by engaging them in a genuine and constructive dialogue with the local airport authorities.

In this regard, ANIMA aims at:

Analysing current noise management practices implemented by airports in order to issue exemplified best practices,

Deepening our understanding of the annoyance mechanisms especially when it comes to non-acoustical factors,

Capitalize these knowledges through a dedicated European Strategic Research Roadmap on noise in order to allow aircraft designers and traffic planners to conceive low-annoyance aircraft and/or procedures on the one hand, and to provide tools and methods allowing non experts to heighten their proficiency on aviation noise.

ANIMA is supported by the European Union‘s Horizon 2020 research and innovation programme under grant No 769 627.

The project ARTEM (Aircraft noise Reduction Technologies and related Environmental iMpact) is devoted to the development of enabler technologies for the low-noise future aircrafts.

With the expected advent of novel configurations as advanced tube-and-wing concepts with lift-producing fuselage and embedded engines or even blended wing body aircrafts, novel approaches are needed to make best use of noise reduction technologies at the source –i.e. at the aircraft itself. This involves the reduction of noise originating from the interaction of different aircraft components - e.g. the jet of the engine with the wing or body surfaces.  Furthermore, innovative means for the absorption of noise and the deflection of noise away from the people below the aircraft are developed.

In a multi-channel assessment and exploitation strategy for the technology development of the project, predictions will be made when these novel technologies are applied to current and future aircraft concepts. Thereby, fly-over predictions and even auralization of the still virtual aircrafts will be possible.

The ARTEM technology development helps keeping up the constant progress which is made for noise reduction at each individual aircraft by feeding novel ideas and technologies in the development process which cumulates in quieter aircrafts with every new generation.

ARTEM is a four year project started in December 2017 and receives funding from the European Union‘s Horizon 2020 research and innovation programme under grant No 769 350.

Nearly 15 years after the last commercial supersonic flight, the quick evolution of technology combined with the emergence of ambitious industrial projects indicate that a second era for environmentally friendly supersonic commercial flights is about to happen.

One of the main obstacles remaining on the path to sustainable supersonic commercial flight is the issue of noise, specifically the loud and sudden sonic boom felt by the populations overflown during the entire cruise. The high level of sonic boom produced by supersonic aircraft at the time led to a complete ban of civilian supersonic flights over land in the United States and several other countries.

Since then “low boom” technologies have emerged, opening the door to regulatory evolutions.

RUMBLE (RegUlation and norM for low sonic Boom LEvels ) is dedicated to the production of the scientific evidence requested by national, European and international regulation authorities to determine the acceptable level of overland sonic booms and the appropriate ways to comply with it. RUMBLE will not aim at producing a low boom aircraft design but rather the quantified evidence needed to support new regulations.

To this end, RUMBLE will associate the leading organizations in supersonic aviation in Europe and Russia, combining scientific excellence, world-class research infrastructures and industrial leadership bearing the heritage from Concorde and Tu-144, with strong involvement in the regulatory bodies.

RUMBLE will develop and assess sonic boom prediction tools, study the human response to sonic boom and validate its findings using wind-tunnel experiments and actual flight tests. Extensive dissemination and regulatory activities will ensure that the European considerations are taken into account in the evolution of the international regulation affecting civilian supersonic flights. RUMBLE will also pave the way for a future low boom flying demonstrator.

RUMBLE is a three year project launched in November 2017 and funded by the European Union‘s Horizon 2020 research and innovation programme under grant No 769896.
