SAIL ANGLE CONTROL METHOD FOR CORVETTE, ANGLE CONTROLLER, AND CORVETTE LOADED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sail control method which enables a sail thrust to be increased by considering a sail interference in a corvette having a plurality of sails.SOLUTION: A sail angle control method includes step S1 for determining a set angle for each sail by the inclination arrangement method, step S2 for simultaneously increasing and decreasing the angles of incidence of a plurality of sails by micro angles by the same amount while keeping an angle difference between determined sail set angles, step S3 for determining a rotation direction where an average value of thrusts by the plurality of sails increases when increasing and decreasing the angles of incidence to further increase and decrease the angles of incidence of the plurality of sails simultaneously by the same amount in the determined direction, and step S4 for determining an optimum set angle of each of the plurality of sails on the basis of angles of incidence where an average value of thrusts by the plurality of sails becomes maximum.
