Systems and methods for providing variable geometry winglets to an aircraft are disclosed. In one embodiment, a winglet includes a base portion configured to attach to a wing. The winglet further includes a body portion. In turn, the body portion includes at least one of a deflectable control surface, a shape memory alloy (SMA) bending plate, and a SMA torque tube. The base portion is configured to attach to the wing such that the body portion projects at an upward angle from the wing.
What is claimed is: 1. A winglet, comprising: a base portion to attach to a distal portion of a wing; and a body portion that includes a controllable section to adjust a shape of the body portion, the controllable section contains at a shaped memory alloy (SMA) bending plate that bends the body portion span-wise relative to the wing and a SMA torque tube that twists the body portion stream-wise, wherein the base portion attaches to the wing such that the body portion projects at an upward angle from the wing. 2. The winglet of claim 1, wherein each o...
