The course provides an overview of key aspects in wind energy engineering as well as design principles of wind turbines. Throughout the course the student will be acquainted in detail with the most fundamental disciplines of wind energy research such as: wind measurements and resource assessment, possible wind turbine designs and their modeling, aerodynamics, structural mechanics, wind turbine manufacturing technology and materials, electrical systems etc, which will be realized through the use of different, simpler analytical, empirical and numerical methods.

The student will gain a rational understanding of wind energy engineering and different wind turbine concepts and design methods. Through hands-on exercises, the student will learn to perform wind energy calculations based on simple models. Working with the different course disciplines (applied mathematics, programming, CFD, structural mechanics, optimization, manufacturing technologies) will enable the student to identify the most interesting and/or relevant aspects of wind energy engineering to be pursued in his/her future studies or professional career or applied on similar structures (propellers, helicopter rotors).
