Rotor Aerodynamics

Rotor Aerodynamics

The lecture will give an insight into the flow around airfoils of unducted rotors such as rotors of wind turbines and helicopters. The lecture will be focused on computational simulation and experiments on rotating airfoils. In addition to the basics of the respective processes, aspects such as determination and maximization of the efficiency are presented and illustrated. The content will be explained with examples from aviation. The lecture is recommended for students who are interested in applied aerodynamics.

Recommended for 7th semester


  • Introduction to stationary aerodynamics of airfoils
  • Unsteady aerodynamics
  • Flow of rotating systems
  • Numerical simulation of flow separation
  • Experimental simulation of flow separation
