Abstract
Official abstract text for this publication.
An apparatus and methods for changing the shape of a wing using a plurality of morphing structures. One example method includes coupling a plurality of morphing structures to each other. Each morphing structure includes an anchor, a plurality of hinges, a plurality of shape-memory alloy members wherein each shape-memory alloy member extends from the anchor to a different hinge, a plurality of springs wherein each spring extends from the anchor to a different hinge, and a plurality of rigid members wherein each rigid member extends between two hinges. The method further includes actuating the plurality of shape-memory alloy members in at least some of the morphing structures wherein the shape-memory alloy members contract when actuated to pull against the hinges and anchors within the actuated morphing structures to rotate the rigid members and change the shape of the actuated morphing structure.
First claim
Opening claim text (preview).
What is claimed is: 1. An internal frame of an aircraft wing, comprising: a morphing structure, the morphing structure, including: an anchor; a plurality of hinges surrounding the anchor; a plurality of shape-memory alloy members wherein each shape-memory alloy member extends from the anchor to one of the plurality of hinges; a plurality of springs wherein each spring extends from the anchor to one of the plurality of hinges; and a plurality of rigid members wherein each…
