Study of Rigid Sail Aerodynamics

Abstract

Authors: Giovanni Lombardi, Joseph Katz, Maurizio Foresta

Keywords: rigid sail, America's Cup, aerodynamics, multi-element airfoil, sailboat racing

Most sailboats use flexible sails to generate the aerodynamic propulsive force. However, for the 2013 America's Cup sailboat competition, rigid sails were specified. These sails resemble an airplane's wing and traditional wing-design tools (computational and experimental) were used to study the performance of the multi-element sail system. The first objective of this study was to identify the possible variables affecting the aerodynamic performance of such sails.
