Dear Colleagues,

The current issues experienced by manufacturers and operators related to the faster-than-expected degradation of mechanical/structural components of large-scale wind turbines has put at risk significant projects and threatens the slowing down of the development of the entire sector. The main aim of this Special Issue is to put together the most up-to-date knowledge in the area to help mitigate or eliminate the mentioned problems. Bearing in mind that sustainable development and wind turbine safety are a must, the editors believe that several options exist, not only to extend the lifespan of existing machines through reduction of loading and wind turbine costs, but also to use alternative designs and concepts that are more suitable than current designs under certain conditions. With the use of emerging technologies, such as AI or additive manufacturing, more efficient models and products can be generated.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

• Reliability centred maintenance;
• O&M and probabilistic modelling;
• Decision analysis;
• Advanced structural modelling and health monitoring;
• Component optimization and redesign options;
• Innovative designs and concepts (e.g., airborne, multirotor, X rotor);
• Use of emerging technologies (e.g., AI, additive manufacturing, digital twins);
• Load alleviation through control engineering and misalignment couplings.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Wind is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
