GAA ECOFAN: Augmented aero-acoustic liners for the design of cooling and air-conditioning fans ecofan

Energy efficiency has been identified as one of the key pillars of decarbonisation in the Net Zero Emissions by 2050 roadmap. It should be specially considered for the development of sustainable cities, as almost 80% of the population lives in towns and consumes 78% of the primary energy. It is estimated that buildings account for 20% to 40% of the total energy consumption in developed countries.

Completed Research Projects

GAA Reduction of acoustic and aerodynamic noise through sustainable micro-pore absorbers linkb20006-mosaico

Land transport and aeronautical industries are currently faced with the challenge of the design of lightweight and compact acoustic materials capable of reducing under flow the low and medium frequency components (< 1 kHz) of surrounding noise sources.

GAA Broadband dissipation through Functionally-Graded Micro Perforated Metamaterials broadband disipation

The problem of lightweight and space-constrained sound absorbers in the low frequency range constitutes an area of continuous research. For instance, aeronautics has an important role to play in reducing noise to support sustainable traffic growth: one of the main challenges of air transport is to attenuate the environmental impact of air traffic despite its continuing expansion.

GAA BROADBAND AND QUASI-PERFECT ACOUSTIC ABSORPTION WITH BIO-INSPIRED HIERARCHICAL METAMATERIALS FOR AIR AND SURFACE TRANSPORTATION SYSTEMS Photography of GCA I with outer diameter 25 mm

Aircraft noise has become a major concern for communities around airports giving rise to stacked legislations and regulations at various levels. Current noise reduction technologies do not seem to achieve the targeted reductions set by the EC experts by the ACARE Flightpath 2050.
