Knowing the wind speed is essential for safe paragliding. At take-offs, cup anemometers are most commonly used to measure speed. In this thesis we focused on the design, construction and testing of a cup anemometer in a wind tunnel. The determination of the wind tunnel reference velocity was carried out using a reference LDA-measurment system. The dimensions and geometry of the anemometer were determined by considering the relevant literature, and a procedure for testing was defined. We found that our anemometer operates within the appropriate operating range and achieves sufficient accuracy for practical use.
