We claim: 1. A vehicle, comprising: a fuselage; and a control surface attached to the fuselage, comprising: an exterior surface, wherein a surface area magnitude of the exterior surface is adjustable; and an adaptive actuator connected to the exterior surface and configured to adjust the surface area magnitude of the exterior surface, wherein the adaptive actuator comprises a polymer foam. 2. A vehicle according to claim 1, wherein the polymer foam comprises a shape memory material. 3. A vehicle according to claim 1, wherein the adaptive actuator is configured to at least one of expand and contract at least 200% of an original length of the polymer foam in a selected direction. 4. A vehicle according to claim 1, wherein the adaptive actuator is configured to adjust the surface area magnitude according to a speed of the vehicle. 5. A vehicle according to claim 1, wherein the exterior surface comprises an exterior surface of the polymer foam and wherein at least a portion of the exterior surface is substantially free of porosity. 6. A vehicle according to claim 1, wherein the exterior surface is configured to at least one of expand and contract in length substantially perpendicular to a direction of travel of the vehicle. 7. A vehicle according to claim 1, wherein the control surface is configured to move from a stowed position to a flight position. 8. A vehicle according to claim 1, further comprising a support module, wherein the polymer foam at least partially surrounds the support module. 9. A vehicle according to claim 8, wherein the support module comprises a movable element configured to at least one of extend and retract according to a movement of the polymer foam. 10. A projectile, comprising: a fuselage; and a deployable wing attached to the fuselage, comprising: an exterior surface; and an adaptive actuator supporting the exterior surface and configured to adjust a surface area of the exterior surface, wherein: the adaptive actuator comprises a polymer foam attached to the exterior surface; the polymer foam is configured to at least one of extend and retract; and the exterior surface is configured to at least one of expand and contract in response to the polymer foam. 11. A projectile according to claim 10, wherein the polymer foam comprises a shape memory material. 12. A projectile according to claim 10, wherein the polymer foam is configured to at least one of expand and contract at least 200% of an original length of the shape memory material in a selected direction. 13. A projectile according to claim 10, wherein the adaptive actuator is configured to adjust the surface area according to a speed of the projectile. 14. A projectile according to claim 10, wherein the exterior surface comprises an exterior of the polymer foam and wherein at least a portion of the exterior surface is substantially free of porosity. 15. A projectile according to claim 10, wherein the exterior surface is configured to at least one of expand and contract in length substantially perpendicular to a direction of travel of the projectile. 16. A projectile according to claim 10, wherein the deployable wing is configured to move from a stowed position to a flight position. 17. A projectile according to claim 10, wherein the deployable wing further comprises a support module, wherein the polymer foam at least partially surrounds the support module. 18. A projectile according to claim 17, wherein the support module comprises a movable element configured to at least one of extend and retract according to a movement of the polymer foam. 19. A method of deploying a wing having an exterior surface, wherein the wing is coupled to a fuselage of a vehicle, the method comprising: providing an actuation signal; and deforming a polymer foam in response to the actuation signal to thereby adjust a surface area magnitude of the exterior surface of the wing. 20. The method of deploying a wing according to claim 19, further comprising moving the wing from a stowed position within the fuselage to a flight position. 21. The method of deploying a wing according to claim 19, wherein deforming the polymer foam comprises deforming the polymer foam in response to a speed of the wing. 22. The method of deploying a wing according to claim 19, wherein deforming the polymer foam comprises at least one of expanding and contracting a length of the polymer foam in a direction transverse to a travel direction of the wing. 23. The method of deploying a wing according to claim 19, wherein the exterior surface is integrated into the polymer foam and wherein at least a portion of the exterior surface is graded and substantially free of porosity. 24. The method of deploying a wing according to claim 19, wherein the polymer foam comprises a shape memory material.
