Abstract
In one aspect, a rotor blade for a wind turbine is disclosed. The rotor blade may include a body extending between a blade root and a blade tip. The body may define a pressure side and a suction side extending between a leading edge and a trailing edge. In addition, the body may define a chord line extending between the leading and trailing edges. The rotor blade may also include an airfoil modifier coupled to at least one of the pressure side or the suction side of the body. The airfoil modifier may define an end surface disposed adjacent to the trailing edge. At least a portion of the end surface may extend at a non-perpendicular angle relative to the chord.

A rotor blade for a wind turbine, the rotor blade comprising:
- a body extending between a blade root and a blade tip, the body defining a pressure side and a suction side extending between a leading edge and a trailing edge, the body further defining a chord line extending between the leading and trailing edges;
- an airfoil modifier coupled to at least one of the pressure side or the suction side of the body, the airfoil modifier defining an end surface disposed adjacent to the trailing edge, at least a portion of the end surface extending at a non-perpendicular angle relative to the chord line.
