Wind turbine blades are the primary components responsible for capturing wind energy and converting it into mechanical power, which is then transformed into electrical energy through a generator. The fundamental goal of blade design is
Routine visual inspections of the key components of wind turbines such as blades, towers, and nacelles are crucial for identifying signs of wear and damage. Inspections may include: Visual checks for cracks, erosion, or leading edge
The wind turbines of the new generation are subject to extreme mechanical and physical loading, can be damaged during service time, and will require maintenance and repair. In this paper, technologies for the
The analysis of the role of defects and voids in adhesives on the post-repair lifetime of wind turbine blades and energy costs is carried out. Using the continuum damage mechanics approach, it is demonstrated that the voids
A short overview of main repair techniques for wind turbine blades and the related problems of computational mechanics is presented. Computational models of the leading edge erosion of wind turbine blades, injection repair and viscous flow, patch/scarf repair as well as curing and adhesive development are reviewed.
The wind turbines of the new generation are subject to extreme mechanical and physical loading, can be damaged during service time, and will require maintenance and repair. In this paper, technologies for the repair and recycling of the new generation of materials for wind turbine blades are reviewed.
The following aspects of the wind turbine repair are considered: general strategy, surface erosion and protective coatings, surface cracking and injection repair, patch repair and the optimal geometry and the adhesive material choice problems. 2. Repair of wind turbines: main steps
Blade maintenance tasks may include: Inspecting surface defects or edge erosion. Repairing or replacing damaged or worn blade sections. Applying protective coatings or leading edge tape to mitigate erosion. Ensuring the structural integrity of wind turbine components is essential for safe and reliable operation.
The proposed hybrid mobile robot, which includes a parallel module with a lightweight base, is promising in effectively polishing large-scale wind turbine blades because of its potential advantages like higher stiffness and flexible A/B axis rotational capacity. The CAD model of this parallel module with a lightweight base is designed and presented on this basis.
Conclusions Repair of wind turbine blades is an important task for energy technologies development, which at some stage can become decisive for the future of renewable energy.
