A system for varying a camber of an airfoil may include an airfoil having an upper surface and a lower surface meeting to form a leading edge and a trailing edge, the lower surface having a first actuator including shape memory alloy sheet, a controller including a plurality of heating elements attached to the shape memory alloy sheet for selectively heating the sheet to a temperature above ambient to deform the upper and lower surfaces to morph a geometry of a camber of the airfoil thereby, a computer control connected to selectively control individual activation of the heating elements to heat the shape memory alloy sheet to a selected temperature to effect a selected deflection, and a cooling device to allow ambient air to enter the wing and exit over the actuator to resume a non-morphed state.

1. A system for varying a camber of an airfoil of a wing of an aircraft, the system comprising: an airfoil having an upper surface and a lower surface, the upper and lower surfaces meeting to form a leading edge and a trailing edge, the upper and lower surfaces each including an outer skin having non-metal outer structural layers;at least one of the upper surface and the lower surface having a first actuator including a shape memory alloy sheet embedded and bonded between the non-metal outer structural layers of the at least one of the upper surface and the lower surface;a controller including a plurality of heating elements attached to the shape memory alloy sheet for selectively heating the shape memory alloy sheet of the first actuator to a temperature above ambient to deform the at least one upper surface and the lower surface having a first actuator along a chord-wise direction to morph a geometry of a camber of the upper surface and the lower surface of the airfoil thereby; anda computer control connected to selectively control individual activation of the plurality of heating elements to heat the shape memory alloy sheet to a selected temperature to effect a selected deflection, and to allow the plurality of heating elements to cool and the shape memory alloy sheet to cool, and the geometry of the camber of the upper surface and the lower surface of the airfoil to resume a non-morphed state;wherein the controller further includes a cooling device for lowering a temperature of the shape memory alloy sheet of the first actuator, the cooling device including vents in the leading edge that may be selectively opened to allow ambient air to enter the wing and exit over the first actuator. 2. The system of claim 1, wherein the geometry includes a camber of the airfoil of a flap of the aircraft wing. 3. The system of claim 1, wherein the controller includes a power distribution panel to activate the plurality of heating elements for selectively heating the first shape memory alloy actuator. 4. The system of claim 3, wherein the heater is selected from a resistance heater, an induction heater, and a heated blower. 5. The system of claim 3, wherein the power distribution panel includes temperature sensors to sense a temperature of the shape memory alloy sheet; and the computer control receives temperature data of the shape memory alloy sheet from the power distribution panel. 6. The system of claim 1, wherein the first actuator includes a plurality of shape memory alloy sheets. 7. The system of claim 1, wherein the shape memory alloy sheet is attached by at least one of an adhesive bond and a plurality of fasteners to the at least one of the non-metal outer structural layers of the outer skin of the upper surface and the outer skin of the lower surface. 8. The system of claim 1, wherein the shape memory alloy sheet contributes to the structural strength of the at least one of the outer skin of the upper surface and the outer skin of the lower surface. 9. The system of claim 1, wherein the shape memory alloy actuator is located at the trailing edge of the airfoil. 10. The system of claim 9, wherein the shape memory alloy actuator is located on a flap at the trailing edge of the airfoil. 11. A system for changing a shape of a camber of an airfoil of a wing of an aircraft, the system comprising: an airfoil having an upper surface and a lower surface, the upper and lower surfaces meeting to form a leading edge and a trailing edge, the upper and lower surfaces each including an outer skin having non-metal outer structural layers;the upper surface including a first actuator having a first shape memory alloy sheet and the lower surface including a second actuator having a second shape memory alloy sheet, the first shape memory alloy sheet embedded and bonded between the non-metal outer structural layers of the upper surface, and the second shape memory alloy sheet embedded and bonded between the non-metal outer structural layers of the lower surface;a controller including a plurality of heating elements attached to the first shape memory alloy sheet and to the second shape memory alloy sheet for activating the first actuator and the second actuator by selectively heating and cooling the first and second shape memory alloy sheets to deform the upper and lower surfaces in a chord-wise direction to change a geometry of a camber of the upper surface and the lower surface of the airfoil thereby; anda computer control connected to selectively control individual activation of the plurality of heating elements to heat the first and second shape memory alloy sheets to a selected temperature to effect a selected deflection, and to allow the plurality of heating elements to cool the first and the second and the shape memory alloy sheets to cool, and the geometry of the camber of the upper surface and the lower surface of the airfoil to resume a non-morphed state;wherein the controller further includes a cooling device for lowering a temperature of the first shape memory alloy sheet of the first actuator and a temperature of the second shape memory alloy sheet of the second actuator, the cooling device including vents in the leading edge that may be selectively opened to allow ambient air to enter the wing and exit over the first actuator and the second actuator.
