AN INVESTIGATION OF GRADUATED TRIM FOR AN AEROFOIL RIG

The advantages of symmetric airfoil sails for wind propulsion of large ships are discussed. Practical realizations of an airfoil rig and associated problems are considered. The proposed airfoil ship, investigated in this paper, is described. A simple two-dimensional analysis using a potential flow representation of wind flow through an airfoil rig is discussed and used to produce various arrays of graduated sail trim angles. Wind tunnel tests of a model airfoil ship are described. Sail force coefficients are obtained for various graduated and parallel trims. A simple performance model is derived and used for the comparative analysis of wind tunnel data.
