AeroLoop - Accelerated and increased quality in aerodynamic and aeroacoustic design loops

The main focus area of the AeroLoop project is to improve the performance of the wind turbine
blade sections for each partner as fast as possible. To do so it is necessary to develop and
implement new measurement methods, benchmark the tunnel against other tunnels, and
demonstrate and tailor the design loops for each manufacturer. In this process, the efficiency of the
tests will be in focus, where both the quality of the tests and the short turnaround cycles are
important.

The outcome of the project will be a general increase of the rotor efficiency, where higher
structural stiffness, lower noise and higher aerodynamic efficiency potentially can increase the
annual energy production. In addition, the losses due to surface roughness or manufacturing
uncertainties will be smaller and AeroLoop will contribute to a reduction of these losses. Lastly,
Aeroloop targets a significant reduction of the noise emission. These improvements will potentially
lead to a big decrease in CO2 emission and a higher competitiveness. The Poul la Cour Tunnel will
be improved and include many features needed for wind turbine manufacturers. This will be due to
the combination of size, acoustic features, increased measurement quality and the reduced time in
the turnaround cycles.
