Leveraging an end-to-end solution for composite wind turbine blades
As they are getting increasingly longer, wind turbine blades need to be stiffer and lighter to avoid cracks from fatigue loading and to help lower foundation construction costs. Current development processes are mainly 2D-based and rely on heterogeneous suites of tools that are not compatible with the quality and stiffness requirements of designing larger blades. Moreover, these tools do not allow to take last-minute engineering changes into account for manufacturing instructions. In this context, wind turbine manufacturers are looking for innovative development solutions – particularly for blade architecture, design, simulation and manufacturing – that will help them meet these requirements while achieving longer life spans without defects.
with the adequate bending strength and in avoiding significant cracks in the aerodynamic structure. Advanced capabilities are needed to generate very high shape quality, i.e. a powerful and complete set of modelling capabilities, free-form and section-based modelling capabilities, realistic and fast quality analysis tools, and shape optimization capabilities. The surface design is then provided to mechanical engineers, who define the detailed design and basic ply guidelines for the blade. Various methods, including zone, grid and solid slicing, are

recent market analysis shows that the number of blades produced per year will go on increasing, with the average blade size also continuing to grow from an average 40-60 m today to 80 m in the future, which raises new challenges.

Optimizing composite blade design

Defining the aerodynamic properties of blades is critical in delivering outer shapes

Dassault Systèmes has worked in close collaboration with major wind turbine manufacturers to meet the industry’s complex challenges and develop end-to-end PLM solutions to design, simulate, and manufacture complete wind turbine generators on a single platform, from tower, nacelle and generators to systems control, rotor, and structural composite components. At the heart of Dassault Systèmes composite solutions, CATIA provides a dedicated environment for the design of composite blades, SIMULIA provides advanced simulation tools and composite-specific methodologies to improve design, increase the value of virtual testing, and significantly reduce reliance on physical testing while meeting regulatory requirements, and DELMIA supplies digital manufacturing capabilities from planning to simulation-based validation, work instruction authoring, and actual delivery to the shop floor.

available for the automatic creation of plies, with full associativity between surface and composite parameters. A rotor blade is generally composed of structural elements such as spar webs and a shell, which are designed as sandwich composites. It is important for the designer to tightly control the properties of composite blades over their lifespan through appropriate optimization of ply orientation, thickness and lay-up. Designing the composite lay-up in line with the complete blade assembly makes it possible to streamline the design process, ensuring a higher level of accuracy and reducing the number of
