A wind turbine blade, including: an airfoil (50) having a pressure side (12), a suction side (14), and a trailing edge portion (20) deflectable from a trailing edge neutral position, and a tensile-only stiffener (52) secured to the trailing edge portion and having a tension center disposed toward the pressure side of and at a distance (54) from an elastic axis (30) of the airfoil when the airfoil is in an airfoil neutral position. |
