Description du projet

Une nouvelle technologie sonore rend les avions plus silencieux

Les avions sont des appareils bruyants, surtout en phase d’approche; les trains d’atterrissage et les dispositifs hypersustentateurs sont les principales sources de bruit. La réduction des niveaux de bruit est une priorité délicate, car la pollution sonore pose un risque important pour la santé humaine. Le projet INVENTOR, financé par l’UE, va étudier la physique du bruit généré par les trains d’atterrissage et les dispositifs hypersustentateurs lors des phases d’atterrissage et d’approche. Rassemblant 16 partenaires (organismes de recherche technologiques (RTO pour research and technology organisations), grandes industries et petites et moyennes entreprises (PME)) originaires de sept pays de l’UE, le projet contribuera de manière significative au positionnement de l’Europe à l’avant-garde du domaine de la réduction du bruit des aéronefs et des solutions en la matière. L’objectif principal d’INVENTOR est de mettre au point un train d’atterrissage, des composants de dispositifs hypersustentateurs et des technologies de réduction du bruit à faible émission sonore innovants, afin de réduire le bruit extérieur généré par les avions d’affaires et les avions de transport court et moyen-courrier.

Objectif

Mitigating aircraft noise on both modern and future aircraft is a significant challenge for the EU considering the increase of air traffic and extension of urban areas together with the increasing public health concern. Aircraft noise results from the combination of engine noise, significantly reduced after decades of intensive research, and airframe noise, mostly generated by landing gears (LGs) and high-lift devices (HLDs). Strong integration constraints imposed by other considerations than acoustics and our limited knowledge of the complex flow physics mechanisms generating airframe noise have so far limited the development of noise reduction technologies (NRTs) on airframe components such as LGs and HLDs. Direct design of low-noise airframe components based on multi-disciplinary criteria (including acoustics), remains a challenge as well.

Therefore, the primary goal of INVENTOR is to better understand the physics of noise generated by LGs and HLDs thanks to intensive use of new, advanced numerical methods. The ultimate goal is to decrease the external noise from business jet and short-medium range transport aircraft through the development of innovative low-noise installed LG and HLD components as well as new promising NRTs, thus contributing to the achievement of the Flightpath 2050 goals pursued by ACARE SRIA on aviation noise. The main Key Performance Indicator in terms of noise reduction will be to lower far-field noise generated by installed LGs and HLDs at landing/approach by respectively 2-3 and 1dB(A). Considering an equal contribution of engine and airframe to noise, we aim to reach an overall gain of about 1 dB(A) on full aircraft extrapolation in approach certification conditions. INVENTOR, gathering 16 partners (RTOs, large industries, SMEs) from 7 EU countries with a budget of €5 M will significantly contribute to Europe’s leadership in aircraft noise reduction and solutions; and increase the competitiveness of the European aviation industry.
