QUIET AEROFOIL WITH ADAPTIVE POROUS SURFACES (QUADPORS)
Lead Research Organisation:
University of Southampton
Department Name: Sch of Engineering
Abstract
Introducing porosity onto an aerofoil has been shown to have a significant influence on the boundary layer and provide significant reductions in its noise radiation. This proposal describes a multi-disciplinary research project aimed at understanding and exploiting the interactions between porous aerofoils and the boundary layers developing over them for the purpose of optimising noise reductions without compromising aerodynamic performance. The use of adaptive manufacturing technology will be investigated for providing the optimum porosity at different operating conditions.

On the Single Mono Porous Line Trailing Edge
| Description | The main outcome of this project is that introducing even a small amount of porosity close to the leading edge and trailing edge of an aerofoil, which has negligible impact on its aerodynaic performance, can produce significant reductions in both leading edge and trailing edge noise. |
| Exploitation Route | This technology is of direct application to wind turbines and other applications involving rotating blades, such as UAVs and drones. |
