Flow conditions and wind shear in the wake of wind turbines. A case study.

6 wind turbines are to be erected near a public airfield. The planned locations of the wind turbines are close to the airfield traffic pattern. For three typical aircrafts operated at the airfield and flying a traffic pattern, potential hazards were determined by entering the wind shear zones of the wind turbines. As a basis for the assumed operating parameters of the aircraft, procedures published in the certified flight manuals (AFM) are assumed. In addition, a sensitivity analysis is performed for deviations from the specified flight parameters and traffic pattern. Numerical flow simulations (virtual wind tunnel) are carried out in order to take into account the local flow conditions (up and down winds). In addition to the flow calculations, a flight simulation of the traffic pattern is realized for an aircraft (soon to be seen on YouTube).
