An apparatus and method for controlling a shape of an outer surface of a control surface. In one illustrative embodiment, an apparatus comprises a control surface and a shaping system associated with the control surface. The control surface is associated with a portion of an aft edge of a wing. The control surface comprises a plurality of segments in which each of the plurality of segments comprises a number of sections. The shaping system is configured to move each segment in the plurality of segments independently of other segments in the plurality of segments to control a shape of an outer surface of the control surface.

The apparatus of claim 1, wherein the shaping system comprises: a plurality of actuation systems, wherein each of the plurality of actuation systems is configured to move a corresponding segment in the plurality of segments independently of the other segments in the plurality of segments. 3. The apparatus of claim 2, wherein the actuation system in the plurality of actuation systems comprises at least one of a hydraulic actuator, a pneumatic actuator, a rotary actuator, a linear actuator, an electric actuator, a shape-memory alloy actuator, and a shape-memory alloy rotary actuator. 4. The apparatus of claim 1, wherein the number of sections includes three sections arranged along a forward-aft direction. 5. The apparatus of claim 1, wherein the plurality of segments comprises: a plurality of inboard segments that form an inboard portion of the control surface; anda plurality of outboard segments that form an outboard portion of the control surface. 6. The apparatus of claim 1 further comprising: a plurality of elastomeric interfaces configured to form a portion of the outer surface of the control surface. 7. The apparatus of claim 6, wherein a first portion of the plurality of elastomeric interfaces are located between the plurality of segments and wherein a second portion of the plurality of elastomeric interfaces are located between the number of sections that form the each of the plurality of segments. 8. The apparatus of claim 6, wherein each of the plurality of elastomeric interfaces is comprised of an elastomeric material selected from one of rubber and a silicone rubber formation. 9. The apparatus of claim 1, wherein the shape of the outer surface of the control surface is controlled to control an overall shape of the wing. 10. A control surface comprising: a plurality of segments in which each segment in the plurality of segments is configured to be moved independently of other segments in the plurality of segments to control a shape of an outer surface of the control surface, such that each segment comprises a number of section mechanisms, wherein each of the section mechanisms is configured to move a corresponding section in the number of sections independently of other sections in the number of sections; anda plurality of elastomeric interfaces configured to form a portion of the outer surface of the control surface, wherein the outer surface of the control surface is substantially continuous and smooth. 11. The control surface of claim 10 further comprising: a shaping system configured to move each segment in the plurality of segments independently of other segments in the plurality of segments to control the shape of the outer surface of the control surface. 12. The control surface of claim 11, wherein the shaping system comprises: a plurality of actuation systems, wherein each of the plurality of actuation systems is configured to move a corresponding segment in the plurality of segments independently of the other segments in the plurality of segments. 13.
