blade series

WINDnovation Engineering Solutions GmbH is the world’s leading designer of rotor blades for wind turbines. Since 2007 we have developed more than 100 rotor blades for all terrains and wind conditions in over 20 countries — more than any other company in this industry.

Below you can find our core services and developments.

Rotor Blade Design

The rotor blades catch the wind to be transformed to electrical energy. Their aerodynamic efficiency is one of the key parameters for a well-working wind turbine. Based on airfoils developed at TU Delft, the WINDnovation blades show high performance, reasonable loads and smooth operational behavior.

The structural design of the rotor blade provides the required mechanical properties (stiffness, flexibility, deflection, natural frequencies, operational characteristics) with minimum material input.

A balanced rotor blade design is always a trade-off between aerodynamics, loads and structural demands. Our engineers deep knowledge and understanding of all design disciplines lead to optimized rotor blade designs well adapted to the requirements of the customers.

Load Calculations

Calculating the loads of all its major components is one of the core tasks in the design process of a wind turbine. In combination with the controller design, the load calculation is highly iterative and complex. Based on the rules and regulations selected, all possible situations that can occur during the lifetime of a wind turbine are simulated and the results are carefully evaluated. These results are documented certification-ready.

Software Tools made by WINDnovation

To develop successful products, it is important to give the project engineers the best possible working environment including efficient and comprehensive calculation tools. This allows the most efficient approach to solve a given task. Freeing the engineers from time consuming routine tasks opens room for creativity to find new solutions.

Over time we have developed efficient and highly specialized software tools for doing rotor blade calculations. The analysis methods implemented in those software tools are in line with international certification standards for rotor blades. Certificates for rotor blades calculated by our software tools have been issued by DNVGL, UL/DEWI-OCC, TÜV, CGC and CCS.

In order to strengthen the cooperation with our international partners, we are currently making our software tools available to rotor blade designers, certification authorities, material suppliers and universities worldwide.

Technology Transfer

WINDnovation engineers have a sound knowledge not only in desktop jobs but also know what to do in order to transfer their engineering jobs into reality. A production start-up for rotor blades can be supported on-site from factory planning to supervision of manufacture and testing of prototypes. WINDnovation engineers worked successfully on such projects in the Netherlands, in Canada and the USA as well as in Korea, India, Brazil and China.

The WINDblades

The WINDblades are a family of rotor blades matching the demands of all major markets. The carefully adjusted balance between performance and loads makes the WINDblades an efficient rotor solution for most pitch controlled wind turbines. The aerodynamic design of our rotor blades is based on recent airfoil developments of TU Delft. WINDnovation integrates those airfoils into blades with excellent performance and smooth operational behaviour. The structural design and the selection of the materials enable rotor blade manufacturers worldwide to successfully produce the WINDblades. Our team for technology transfer provides comprehensive and efficient support to the start-up of rotor blade manufacture.
