Zusammenfassung: | The invention relates to the technical field of sails, in particular to an airfoil sail. The airfoil sail comprises a sail body, horizontal end plates are installed at the upper end and the lower endof the sail body respectively, and the peripheral edges of the end plates extend out of the end face of the sail body in a suspended mode; or the sail comprises a sail body, the sail body is in a curved surface shape, and the sail body twists towards one side of the sail body from top to bottom; or the sail comprises a sail body, horizontal end plates are installed at the upper end and the lower end of the sail body respectively, the peripheral edges of the end plates extend out of the end face of the sail body in a suspended mode, the sail body is in a curved surface shape, and the sail bodyis twisted towards one side of the sail body from top to bottom. The twisted design can enable the airfoil sail sections at different heights to achieve the optimal airflow attack angle, the boostingeffect of the sail is impro |
