Aerodynamic force coefficients were obtained for the model which has eight rectangular sails with symmetric uncambered NACA0018 section. A symmetric section was used so the airfoils may be used with the wind incident on either face. Tests were run with three types of sail set; with sails parallel, with trim angles graduated to attempt identical local flow conditions at all airfoils, and with trim angle reduced in equal steps of n degrees working from bow to stern. Runs were made at various inflow angles. Details of the aerodynamic interaction between sails are noted.
