Joint Blade Rotor A/S is established to test and market the patented joint blade system.

The system is sprung out of research within one of the Danish universities; Aalborg University (AAU), Department of Mechanical and Manufacturing Engineering (M-Tech). With their expertise of aerodynamics an alternative design of a blade for horizontal axis wind turbines (HAWT) was developed.

The design differs dramatically from a standard design and was patented by the inventors. Next step was then to test the design in full size version, which had to move outside the university offices. For this purpose JBR was established. 

There has been tremendous interest from investors, and a well-funded company was established to take over the project from Aalborg University. All rights and patents were transferred to JBR, which is now partly owned by AAU, and partly by private investors as well as early stage investment funds. The investors and investment funds have majority of ownership.

Of course tests and documentation of results are still focus areas for Joint Blade Rotor A/S. At the moment testing is carried out in cooperation with Nordic Folkecenter.

Finding the best ways of utilizing the patent in the market is an even bigger focus area. Potential business partners for future production and go-to-market channels are therefore welcome to make contact. At this point, no exclusive co-operation models in the market are established.


A full size prototype (8m) has been produced and has undergone various tests. 

The first rotor set undergoes right now performance test on a live turbine on a site in Thy, Denmark.

Most important is, that efficiency is improved significantly giving an improved power production percentage in low winds of around 20%.

JBR will solely focus on blade development and there is no strategy to either develop or to produce and/or market a wind turbine. Therefore, a closer cooperation with a turbine producer will be important for the long-term market development as well as with refurbish companies.
