Kitesurfing is a water sport in which the surfer glides over the water on a table, tied by a harness to a kite. The kite is an essential element among those used in this sport, as it supplies the impulse needed both for sailing and surfer's equilibrium. In this work the effect of modifying the kite's geometry was study in order to obtain a better performance and/or stability. The central section of the kite was designed and printed in 3D with the aim to study it in a wind tunnel. Changes of the kite's geometry were simulated by adding scotch tape in the intrados. The SolidWork software was used in the design of the central section of the kite. Surfplan, a software designed specifically for the study of the kites and parachutes was also used. Additionally, a specific support was designed in order to hold the kitemodel in the wind tunnel, as the support used for airfoils was inadeuate. After wind tunnel testing and subsequent analysis of the experimental data it was observed that that lift coefficients are virtually identical in all the studied cases. However, the drag coefficient was found to decreases in some configurations, resulting in an improvement from the initial model geometry.
