Anakata has partnered with the Hong Kong University of Science and Technology, world leaders in the field of aerofoil noise control.

We use the same simulation, anechoic chamber and validation process and techniques as deployed for Airbus in their efforts to reduce aircraft wing noise.

By analysing the full hearing-range spectra, specific frequencies of blade noise can be mitigated effectively from our validated process. Our solutions can reduce noise beyond what the industry standard serrations can deliver.

All Tip Boosters come with integral noise suppression serrations fitted. As well as reducing noise, the breaking down of the shear layer on the blade produces fatigue life benefits by reducing the magnitude of unsteady loads.

We have developed Serrations that are fitted to the trailing edge of blades. Our Serrations have more complex geometries than standard industry Serrations to better reduce noise emissions and can be tailored to individual blades to deliver better performance.

We have also designed bespoke solutions to help overcome noise problems including metallic Tip Boosters that can provide far better control of airflow over blade tips to help reduce noise sources, improve the LPS of the blade, and also some additional AEP.

We have also developed and installed Amplitude Modulation reduction solutions, following a detailed analysis of the causes of Amplitude Modulation on a given wind farm, and the design of specific parts to reduce the causes of Amplitude Modulation.

Please contact us if you have noise related curtailment issues and require the best solution possible.
