Most sailboats use flexible sails for generating the aerodynamic propulsive<br>force. However, for the 2013 America’s Cup sailboat competition, rigid sails<br>are specified. These sails resemble an airplane’s wing and traditional wingdesign<br>tools, computational and experimental, are used to study the<br>performance of the current multielement sail. The geometry of the proposed<br>sail is based on two, tandem, symmetric airfoils, resulting in a geometry,<br>mainly in the gap between the two airfoils, unlike any traditional two-element<br>airfoil. Therefore, the main objectives of this thesis are to identify the primary<br>parameters affecting the aerodynamic performance of such sails and at the<br>same time, to evaluate the effectiveness of simple computational and<br>experimental tools for such a design exercise. The present work was carried<br>out at the Department of Aerospace Engineering at San Diego State<br>University, San Diego, California, as part of the agreement and cultural<br>exchange between the University of Pisa, Pisa, Italy and San Diego State<br>University, SDSU.
