This research explored the use of deep learning to classify impact events on wind turbine blades using spectrogram images. Audio data were recorded through indoor and outdoor simulations using smartphones. The data preparation process involved converting stereo recordings to mono, applying downcasting …

3D lithography by two-photon photopolymerization enables the fabrication of complex microstructures that incorporate nanomaterials assembled in a controlled manner. This technology holds promise in various fields such as optics, photonics, biology, and nanomedicine. It is also being used in the renewable …

Fluorescent Penetrant Inspection (FPI) is a widely used inspection technique in the aerospace industry. Because of the aging aerospace sector, and because of the safety-criticality of the inspection, aerospace companies aim to automate (parts of this) inspection process to support inspectors. This paper …

AIRTuB Work Package 6 event at Entrance on modelling erosion.

Bulk molding compound (BMC) thermoset (bio) composites are difficult to recycle because they cannot be melted for reprocessing. However, this group of materials is often used in high-end applications where strength and lightweight materials are required, such as boat hulls, aircraft parts, car parts, …

This study originates from an increasing demand for seaweed cultivation. HZ University of Applied Sciences, together with farmers, under the umbrella “Living Lab Schouwen Duiveland” will conduct a field study to assess the possibilities for introducing brown seaweed cultivation at or near existing mussel …

Dynamic stall phenomena carry the risk of negative damping and instability in wind turbine blades. It is crucial to model these phenomena accurately to reduce inaccuracies in predicting design driving (fatigue and extreme) loads. Some of the inaccuracies in current dynamic stall models may be due to …

Dynamic stall phenomena bring risk for negative damping and instability in wind turbine blades. It is crucial to model these phenomena accurately to reduce inaccuracies in predicting design driving (fatigue) loads. Inaccuracies in current dynamic stall models may be due to the facts that they are not …

Blades worden gebruikt bij hardlopen en verspringen door protheselopers. Bij langdurig gebruik kan de stijfheid van een blade afnemen. De stijfheid kan invloed hebben op de stapfrequentie, de contacttijd en de hoek van de blade ten opzichte van de grond. Door veranderingen in deze factoren moet de atleet …

This research proposes new structural lay-outs for large wind turbine blades. The lay-outs were found by an optimisation method where the aerodynamics of wind turbine blades was combined with the structural model of the blade, formulated in a corotational framework. The aeroelastic blade loads were calculated …
