ABSTRACT:
A control fin assembly for a water vehicle includes a multiplicity of fins onnected together and grouped in an array mounted on the vehicle. A portion of the array is of a shape-memory material responsive to heat to assume selected shapes different from the shape of the array portion otherwise. The array portion is electrically conductive and adapted to increase in temperature upon application of electrical current thereto to effect the assumption of the selected shapes.
The invention further relates to a control fin for a water vehicle, at least a portion of the fin being of a shape-memory material responsive to heat to assume selected shapes different from the shape of the fin otherwise, the fin portion being electrically conductive and adapted to increase in temperature upon application of electrical current thereto to effect the assumption of the selected shapes.
