T1 Development of an aerodynamic model for a flexible kite for wind power generation
A1 Peña Cano, Roberto
AB In this bachelor's thesis an Aerodynamic an Structural model have been developed forthe study of a exible kite. With this model, a designer is able to obtain a preliminaryview of the forces acting on a kite as well as the  nal shape of the kite after the equilibriumof forces is reached.The project can be clearly divided in two parts: The Aerodynamic model and theStructural model.The Aerodynamic model is a 3D Vortex lattice method. The Biot-Savart law was usedto get the ow- eld around a  nite straight vortex line. With the boundary conditionthat the air cannot ow through the kite, the strength of the ow- eld induced by thevortices can be computed. Also the Kutta-Joukowski theorem is used to calculate theforce produced by each vortex segment. Once the forces are known, the lift and the induceddrag are also computed. This forces will be used later, together with the structuralmodel, in order to obtain the equilibrium position of the kite.The Structural model is obtained applying two conditions: each segment that composethe kite should be in equilibrium, i.e. the forces and the moments acting on each segmentshould be equal to zero. The other condition is that the two tethers come together in onepoint. It is indispensable that all the segments in which the kite is divided have the samelength, to ensure the convergence. All of these condition will be explain better in section3. A remarkable assumption is that the sti ness of the kite is not taken into account.Both the Aerodynamic model and the Structural one have been developed using Matlab®.
