A helicopter (2) includes an airframe (4), and a rotor system (8) mounted to the airframe. The rotor system includes a plurality of rotor blades (10-13). Each of the plurality of rotor blades includes a root portion (22) that extends to a tip portion (23) through an airfoil portion (24). The airfoil portion includes first (27) and second (28) surfaces. An effector (70-72) is mounted within the airfoil portion of at least one of the plurality of rotor blades. The effector includes a first end portion (80) that extends to a second end portion (82) through an intermediate portion (83), and a flap (86) arranged at the second end portion. The effector is selectively actuated to shift from a first, stowed, position wherein the flap is positioned within the at least one rotor blade to a second, deployed, position, wherein flap projects through at least one of the first and second surfaces of the at least one rotor blade. |
