Duration: 1988-1995

Operating Agent: Institute for Computer Agent Applications (lCA), University of Stuttgart, Germany

Participants: Germany, the Netherlands, Sweden

Objectives: The experimental study of aerodynamics, operational behavior, load spectra and control strategies for different hub concepts, as well as the validation of computer codes via the UNIWEX turbine.

Progress and Achievements


UNIWEX is a computer-controlled, two-bladed experimental wind turbine of 16 m diameter installed at the Ulrich Hiitter wind test field near Schnittlingen, Germany. The main goals of the project were the experimental study of aerodynamics, operational behavior, load spectra and control strategies for different
hub concepts, as well as the validation of computer codes.

The project was technically completed in 1992. A short summary report of 52 pages on the German contribution was submitted in 1993. The Operating Agent presented an extended and more detailed final report, including the contributions from the Neiherlands and Sweden, to the Executive Committee at their meeting in April 1995.

The direct results were listed under these headlines:

  • Development of hardware and software
  • Validation of numerical codes (PHATAS II, FLEXLAST, DUWECS, ARLIS)
  • Simulation and comparison of concepts
  • Experimental studies of different turbine configurations
