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.

Downstream porosity for the reduction of turbulence-aerofoil interaction noise
in Journal of Sound and Vibration
| Description | The main outcome from this project so far is that significant reductions in leading edge and trailing edge noise can be achieved using porosity located downstream and upstream of the leading edge and trailing edge respectively. This is an important outcome as it minimises the impact on aerodynamic performance. |
| Exploitation Route | Through its implementation on rotors and propellers and fans. The main sponsors of this project have been kept informed of key developments. |
