| 发明名称 | Wingsail with adaptable flexible flap | ||
| 摘要 | Wingsail. The wingsail includes a substantially rigid airfoil section having a leading and a trailing edge and a flap is attached to the trailing edge through a torsion fitting having a torsional stiffness along the span of the rigid airfoil section selected to control flap deflection with respect to the rigid airfoil section under aerodynamic loading to control rolling moment of the wingsail. | ||

| 主权项 | 1. Wingsail comprising: a substantially rigid airfoil section having a leading and a trailing edge; and a flap attached to the trailing edge only through a torsion rod fitting providing a substantially linear torque/angular displacement relationship and having a torsional stiffness along the span of the rigid airfoil section selected to control flap motion adaptively with respect to the rigid airfoil section under aerodynamic loading to control rolling moment of the wingsail. | ||
