A system for changing a shape a structural spar includes, in an exemplary embodiment, a plurality of adjoining structural strips axially aligned to form the structural spar. At least one of the structural strips is formed from a shape memory alloy. The system also includes a temperature control system to control a temperature of the at least one shape memory alloy strip. Heat applied to the at least one shape memory alloy strip causes the structural spar to twist or bend.
