- Forces_on_sails abstract "Forces on sails are primarily due to movement of air near and relative to the sails.Understanding the forces on sails is important for the design and operation of the sails and whatever they are moving, sailboats, ice boats, sailboards, land sailing vehicles or windmill sail rotors.Aerodynamic forces from air pressure differences and air viscosity acting near the sail occur along the entire surface of the sails, but can be summed into one net force vector. Net aerodynamic force may be decomposed with respect to a boat's course over water into components acting in six degrees of freedom. Two components with respect to wind direction can also be resolved: drag, which is the component directed down wind, and lift, which is the component normal to the wind and perpendicular to drag. This analysis is important to boat design, operation, balance, stability, seakindliness and seaworthiness.Briefly, when the sail is oriented at a right angle to the wind, as in a boat sailing downwind, the aerodynamic force is almost entirely derived from the form drag component - the wind "pushes" the sail along in the direction of the wind.When the sail is arranged across or into the wind the sail acts as an airfoil. The resulting surface force includes a lift or pressure component normal to the sail surface as well as a tangential drag stress component. Various mathematical models explain the extent and direction of the aerodynamic force on the sail(s). By the law of conservation of momentum, the wind moves the sail as the sail redirects the air backwards .".
