An articulated control surface is provided for hydrodynamic control utilizing a moldable control surface. The central surface is shaped by contracting and elongating wire bundles fabricated with shape-memory alloys located in an adjacent cooling chamber. The shape-memory alloys contract when heated via an applied electric current and elongate when cooled, i.e., the electric current is removed. A pair of wire bundles is anchored inside the cooling chamber. Each bundle is routed over several pulleys in such a manner that a lateral movement is produced at t...
An improved moldable control surface system wherein the improvement comprises: means for shaping said moldable control surface, located external to and remote from said moldable control surface and having linear actuating elements which contract upon heating and expand upon cooling; means for cambering said moldable control surface affixed to the trailing edge structure of said control surface, one of said linear actuating elements connected to and driving a first side on said means for cambering in a first direction and another of said linear actuating ...
