Накратко на български

Нови материали и форми, като зъбчати ръбове на крила, се изследват за намаляване на шума от самолети, коли и вятърни турбини. Това помага за постигане на екологични цели и намаляване на шумовотото влияние върху хората.

Smart mitigation of flow-induced acoustic radiation and transmission for reduced aircraft, surface transport, workplaces and wind energy noise

A step change in our noise mitigation strategies is required in order to meet the environmental targets defined for a number of sectors of activity affecting people through noise exposure, such as air / ground transportation and wind energy production. Radically new concepts for flow and acoustic control, such as meta-materials, porous treatment of airframe surfaces, airfoil leading-edge or trailing-edge serrations, … appear nowadays promising, however still largely as the result of extensive trial-and-error tests conducted at laboratory scale. It appears that the development and maturation of novel noise reduction technologies was hindered by several factors: 1) an insufficient understanding of the physical mechanisms responsible for the alteration of the flow or acoustic fields; 2) very tight design constraints are imposed to any novel noise mitigation strategy making its way to the full-scale application; 3) there is an insufficient knowledge about the possibilities that are nowadays offered by new materials and new manufacturing techniques. SmartAnswer implements a research and training platform focused on innovative flow and noise control and optimization approaches addressing the above shortcomings. It has the following objectives: - foster a training-through-research network of young researchers, where the ESR fellows investigate promising emerging technologies for noise reduction, by means of laboratory experiments, simplified theoretical models and numerical simulations. - bring in a coordinated research environment industrial stakeholders picked from the aeronautical, automotive, wind turbine and cooling/ventilation sectors. - offer a training infrastructure where the young researchers will be confronted with the design, manufacturing and economical constraints by strong interactions with the industrial final users. The research carried out during the project addressed the noise generation and propagation mechanisms, and proposed innovative mitigation strategies accounting for their performance, complexity of integration, space, weight, durability, costs, etc. The research is relevant to many sectors of activity, addressing more specifically automotive cooling fans, wind turbine blades, aeroengines and building ventilation fans.

Цел на проекта

A step change in our noise mitigation strategies is required in order to meet the environmental targets set for a number of sectors of activity affecting people through noise exposure. Besides being a hindrance to our daily life and subject to regulations, noise emission is also a competitive issue in today’s global market. To address these issues, new technologies have been emerging recently, based on radically new concepts for flow and acoustic control, such as micro-electro-mechanical devices (MEMs), meta-materials, porous treatment of airframe surfaces, airfoil leading-edge or trailing-edge serrations, micro-jets, plasma actuation, … Some of these new ideas appear nowadays promising, but it now appears to this consortium that the development and maturation of novel noise reduction technologies is hindered by three main factors. The first factor is an insufficient understanding of the physical mechanisms responsible for the alteration of the flow or acoustic fields. In absence of a phenomenological understanding, modelling and optimization can hardly be successful. Secondly, tight constraints (safety, robustness, weight, maintainability, etc.) are imposed to any novel noise mitigation strategy trying to make its way to the full-scale industrial application. Thirdly, there is an insufficient knowledge about the possibilities that are nowadays offered by new materials and new manufacturing processes. With this project, we intend to setup a research and training platform, focused on innovative flow and noise control approaches, addressing the above shortcomings. It has the following objectives: i) fostering a training-through-research network of young researchers, who will investigate promising emerging technologies and will be trained with the inter-disciplinary skills required in an innovation process, and ii) bringing in a coordinated research environment industrial stakeholders from the aeronautical, automotive, wind turbine and cooling/ventilation sectors.
