초록

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.

청구항

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...
