In the early days of aviation, wind tunnels were developed to investigate whether an aircraft is capable of flying, and how capable it was of doing so.They are mainly used as a part of research of aerodynamic forces applied to a model of an aircraft or its parts. There are several methods of measuring the airflow inside a wind tunnel, however this manuscript is concerned with implementation of Particle Image Velocimetry (PIV), especially the software part, in the conditions of the wind tunnel of the Department of Air Transport. The functions of the software were investigated on the basis of a simple experiment. The poppy seeds were blown on white paper and the images were captured by the camera in slow motion as it moved from side to side and then the images were processed and analyzed. The amount of poppy seeds used varied.The results showed successful use of PIV software and it’s application directly in the wind tunnel of the Department of Aviation for research of the effects of aerodynamic forces in aviation, but also in other areas.
