An apparatus is provided that includes a body having a first wall and a second wall, at least one appending structure extending from an end of the body and at least one actuator positioned between the first and second walls. The actuator includes first end coupled to a portion of the body and a second end coupled to a portion of the appending structure. At least one shape memory alloy (SMA) wire is connected to and extends between the first and second ends of the actuator. The SMA wire is adapted to controllably constrict when activated by heat, whereby ...

What is claimed is: 1. An apparatus comprising: a body including a first wall and a second wall; at least one appending structure extending from an end of the body, the appending structure including a first skin having a proximal end movably positioned between the first and second walls and a second skin coupled at a proximal end to an edge portion of the second wall, a distal end of the first skin connected to a distal end of the second skin; and at least one actuator positioned between the first and second walls, the actuator comprising: at least one shape memory alloy (SMA) wire adapted to constrict when activated to move the appending structure from a first position to a second position; a fixed pulling bracket connected to a first end of the at least one SMA and fixed to an inner side of the first wall, between the first and second walls; and a sliding pulling bracket connected to a second end of the at least one SMA and fixed to a tab extending from the proximal end of the first skin between the first and second walls. 2. The apparatus of claim 1, wherein the distal ends of the first and second skins are fixedly connected. 3. The apparatus of claim 2, wherein the distal ends of the first and second skins are fixedly connected utilizing at least one of rivets, welding and diffusion bonding. 4. The apparatus of claim 1, wherein the SMA wire is coupled at a first end to the fixed pulling bracket and coupled at a second end to the sliding pulling bracket such that when the SMA wire constricts the sliding pulling bracket and the first skin are pulled toward the fixed pulling bracket to move the appending structure from a first position to a second position. 5. The apparatus of claim 4, wherein the SMA wire comprises swaged fittings at the first and second ends to couple the SMA wire to the fixed pulling bracket and the sliding pulling bracket. 6. The apparatus of claim 1, wherein the SMA wire is activated by an increase in temperature of air flowing adjacent the first wall of the body and the connected first skin of the appending structure. 7. The apparatus of claim 6, wherein the SMA wire is deactivated by a decrease in temperature of the air flow. 8. The apparatus of claim 1, wherein the SMA wire is activated by connecting the SMA wire to an electrical current source such that current flows through the SMA wire. 9. The apparatus of claim 8, wherein the SMA wire is deactivated by disconnecting the SMA wire from the electrical current source such that the current no longer flows through the SMA wire. 10. The apparatus of claim 8, wherein the actuator comprises a plurality of SMA wires electrically connected by jumpers such that the current flows through all the SMA wires when activated. 11. The apparatus of claim 1, wherein the second skin acts as a biasing device to return the appending structure to the first position when the SMA wire is deactivated. 12. The apparatus of claim 1, wherein the body comprises a jet engine nacelle. 13. A jet engine nacelle adapted to controllably alter a flow of exhaust emitted from the nacelle, said nacelle comprising: a nacelle nozzle having a body including an inner wall and an outer wall; a plurality of flow altering structures extending from an end of the body, each flow altering structure having an inner skin with a proximal end movably positioned between the inner and outer walls and an outer skin fixedly coupled at a proximal end to an edge portion of the outer wall, a distal end of the inner skin connected to a distal end of the outer skin; and a plurality of actuators positioned between the inner and outer walls, each flow altering structure having a plurality of the actuators connected thereto, each actuator comprising: a fixed pulling bracket coupled to an internal side of the inner wall; a sliding pulling bracket connected to an internal side of a tab extending from the proximal end of the inner skin; and a plurality of shape memory alloy (SMA) cables coupled at a first end to the fixed pulling bracket and coupled at a second end to the sliding pulling bracket, the SMA cables adapted to one-dimensionally constrict along a longitudinal center line of each respective SMA cable when activated, the constriction pulling the sliding pulling bracket and the inner skin toward the fixed pulling bracket to move each flow altering structure from first position to a second position. 14. The nacelle of claim 13, wherein the distal ends of the inner and outer skins are fixedly connected. 15. The nacelle of claim 13, wherein each SMA cable comprises swaged fittings at the first and second ends to couple each SMA cable the respective fixed pulling bracket and the respective sliding pulling bracket. 16. The nacelle of claim 13, wherein each SMA cable is connected to an electrical current source whereby each SMA cable is activated by turning on the electrical current source such that current flows through the SMA cables. 17. The nacelle of claim 13, wherein the outer skin of each flow altering structure is adapted to act as a biasing component to return the flow altering structures to the first position when the SMA cables are deactivated.
