Organization Type

The present research project aims at developing the new generation of TE design solutions for rotating blades. Most promising materials for noise absorption are open foams. Half-open foams are conventionally manufactured with isotropic holes and mainly used as noise dampers. Modern 3D printing technologies allow the creation of new metallic open foams with several innovative characteristics, including coating and activation of the material shape. The main deliverables of the project are:
1) aerodynamic and aeroacoustics study of the flow properties of such materials and prototyping of a foam insert to be installed at the edge of a wind turbine blade/airfoil
2) specification of the optimal porosity characteristics for the foams (to be produced by other team members) and validation of the predicted effects on noise reduction
3) study of the scalability of such devices to higher Reynolds numbers and angles of attack.
