A helicopter includes an airframe, and a rotor system mounted to the airframe. The rotor system includes a plurality of rotor blades. Each of the plurality of rotor blades includes a root portion that extends to a tip portion through an airfoil portion. The airfoil portion includes first and second surfaces. An effector is mounted within the airfoil portion of at least one of the plurality of rotor blades. The effector includes a first end portion that extends to a second end portion through an intermediate portion, and a flap 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.

1. A helicopter comprising: an airframe;a rotor system mounted to the airframe, the rotor system including a plurality of rotor blades, each of the plurality of rotor blades including a root portion extending to a tip portion through an airfoil portion, the airfoil portion having first and second surfaces; andat least one effector mounted within the airfoil portion of at least one of the plurality of rotor blades, the at least one effector including a first end portion that extends to a second end portion through an intermediate portion, and a flap arranged at the second end portion, the effector being selectively actuated to pivot about the first end portion to shift the flap 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. 2. The helicopter according to claim 1, wherein the flap extends substantially perpendicular relative to the intermediate portion. 3. The helicopter according to claim 1, further comprising: an actuator mounted in the airfoil portion of the at least one rotor blade, the actuator being selectively activated to shift the flap through the one of the first and second surfaces of the at least one rotor blade. 4. The helicopter according to claim 3, wherein the actuator is selectively activated to shift the flap through each of the first and second surfaces of the at least one rotor blade. 5. The helicopter according to claim 1, wherein the at least one effector includes a plurality of effectors, each of the plurality of effectors being selectively shiftable between the stowed position and the deployed position. 6. The helicopter according to claim 1, wherein when in the deployed position, a first portion of the flap projects through the first surface of the at least one rotor blade and a second portion of the flap projects through the second surface of the at least one rotor blade. 7. The helicopter according to claim 1, wherein the at least one effector is mounted adjacent the tip portion of the at least one rotor blade. 8. A method of actively controlling a rotor blade of a rotary-wing aircraft, the method comprising: rotating an effector to deploy at least one flap through a surface of the rotor blade. 9. The method of claim 8, further comprising: selectively deploying the at least one flap through a first surface of the rotor blade and through a second, opposing surface of the rotor blade. 10. The method of claim 8, further comprising: deploying a first flap through a first surface of the rotor blade and a second flap through a second, opposing surface of the rotor blade. 11. The method of claim 8, further comprising: simultaneously deploying the first flap through a first surface of the rotor blade and the second flap through a second, opposing surface of the rotor blade. 12. An active rotor blade control effector mounted within an airfoil portion of a rotor blade, the active rotor blade control effector comprising: a first end portion that extends to a second end portion through an intermediate portion; anda flap arranged at the second end portion, the effector being selectively actuated to pivot about the first end portion to shift the flap from a first, stowed, position wherein the flap is positioned within the rotor blade to a second, deployed, position, wherein flap projects through at least one of first and surfaces of the rotor blade. 13. The active rotor blade control effector according to claim 12, wherein the flap extends substantially perpendicular relative to the intermediate portion. 14. The active rotor blade control effector according to claim 13, further comprising: an actuator operatively coupled to the first end portion of the effector, the actuator being selectively activated to shift the flap through the one of first and second surfaces of the rotor blade. 15. The active rotor blade control effector according to claim 13, wherein the actuator is selectively activated to shift the flap through each of first and second surfaces of the at least one rotor blade. 16. The active rotor blade control effector according to claim 13, wherein the effector is mounted adjacent a tip portion of the at least one rotor blade.
