Team Leader

Team Leader

The close coordination between the team leaders guarantees our successful projects and a motivated team.



The aerodynamic layout is based on high performance airfoils specifically designed for the use for rotor blades of wind turbines. In the transition area between the main and outer part of the blade and the circular blade root, airfoils with high relative thickness are used to fulfill the high structural requirements.



The geometry of the rotor blade is the outer surface in contact with the wind. The geometry is mainly defined by the aerodynamics layout but also has to fulfill requirements coming from the manufacturing process. It is the basis to produce the master plug and later the production moulds.

Loads & Controls

Loads and operations management

The loads simulation is one of the essential tasks of the turbine design process with strong effect on the successful rotor blade design.

In the iterative and interactive process of rotor blade design, the loads calculation team supports the aerodynamic design and structural design teams during each step of the design process.

For the calculation of rotor blade loads, we rely on a combination of in-house tools and the industry standard software Bladed.


Cutting-edge software

Our blades are analyzed for aeroelastic stability and flutter stability with inhouse codes and commercial codes like BLADMODE (developed by ECN) and HAWC2STAB (developed by DTU).

In case customer calculated loads are considered in the blade design process, we have established interfaces to most commercial load calculation software packages. We support our customers in processing their loads data if needed.

Manufacturing Technologies

Full-Service Solutions

Once a rotor blade has been fully developed it can be handed over to pro­duc­tion with our support. Our team “Manufacturing Technologies” is in charge of this. Our Manufacturing Technology specialists can support you in everything from individual pro­duc­tion proc­ess steps right through to manufacturing the entire rotor blade.

The members of this team have rich international project experience in  the USA, Netherlands, India, China, Korea and Brazil and they are directly supported by colleagues from the team “Structural Design”.

Research & Development

Continuous improvement

The research and development team supplies all other teams with the newest methods and processes as well as most advanced soft­ware solutions.

We are addressing current issues and challenges by  making use of our extensive experience from many suc­cess­ful projects. We also partner with various colleges and universities  in the context of student research papers, graduate theses and joint research and development projects.

Intensive communication with other companies – for example within the German rotor blade alliance – delivers a steady stream of new insights that we can leverage to continuously improve our products.

We are in constant contact with man­u­fac­turers of the materials used in producing rotor blades, and assess the newest developments in terms of their technical and economic potential to improve our products. This guarantees that we are well-placed to deal with future challenges, and to work efficiently with the goal of securing our customers’ long-term success.

Rotor Blade Test

Meeting certification requirements

In order to proof the durability of a rotor blade design and to check the quality of the production, static and fatigue testing before going in mass production is important and a mandatory certification requirement.

Worldwide rotor blade tests

We accompany tests all over the globe either by supervising professional test institutes or by performing tests on-site using our own test equipment. The different environmental conditions like temperature or humidity need to be considered according to the certification guideline to make the test successful and accepted by the authority selected.

Our highly experienced team of rotor blade test engineers guide, support and supervise your tests. They also keep close contact to the structural engineers in our Berlin office. That enables us to work fast and efficient to make your rotor blade project a success.

Structural Design

Initialization and optimization

Designing a rotor blade structure can begin as soon as the geometry is fixed, the loads affecting the blade are known, and the materials to be used in the blade have been selected. Based on this information we produce a computer internal model of the rotor blade that is analyzed in full and then progressively optimized until all of the customer’s requirements are met.

To achieve an as small as possible blade mass is our focus to make the rotor blade technically and financially competitive.

Our engineers also have years of experience in fiber composites, which they apply with the aim of constantly improving WINDnovation rotor blades.

Software used by WINDnovation

We want to give our design engineers the maximum possible freedom to be creative in solving customer’s challenges. So we typically use software packages developed in-house that release the design engineers from as many routine tasks as possible.

We also use software such as ANSYS, SOLIDWORKS, FINSTRIP, AutoCAD and HAWC2STAB for specific tasks. Furthermore, we are using the multivariate tool pSEVEN for optimization tasks.

Certifying a rotor blade

The final stage of rotor blade design generally involves certification granted by an independent certification body, such as DNVGL, DEWI-OCC or TÜV. We are an active participant in this certification process on behalf of our customers.

Turbine Design

The perfect wind turbine

The perfect wind turbine possesses a perfectly aligned mix of components that, as a whole, are precisely adapted to the con­di­tions of the relevant site. Accordingly, a detailed planning of the entire project is mandatory to an efficient use of development, production and funding plans.

Often, customers of WINDnovation Turbines are about to build their very first turbine. We are aware of the fact that designing a wind turbine is very complex. At WINDnovation we take great care that our customers understand all the important details they need to know, in every phase of the project.

Generally all WINDnovation Turbines projects go through three phases:

  1. Project Planning
  2. Turbine design
  3. Turbine installation and certification

The best engineering team in the industry

WINDnovation’s performance relies on its core resource: outstanding engineering teams.

We work together to develop solutions in every area of wind turbine technology. Though each team has its own focus, the goal at the end of every project is to produce an integrated solution that perfectly fulfills the task at hand. To this end, colleagues communicate constantly and intensively across all departments and all hierarchy levels.
