ABSTRACT:
An articulated control surface for flight control utilizes a moldable conl surface that is shaped by contracting and elongating shape memory alloys embedded within the control surface. The shape memory alloys contract when heated via an applied electric current and elongate when cooled, i.e., the electric current is removed. The resulting control surface is capable of generating a curved control surface without any electro/mechanical or hydraulic control systems.
