A continuous morphing aircraft wing can provide significant aerodynamic advantages over traditional control surfaces. This paper proposes, analyzes, and optimizes the design of a feasible morphing airfoil with embedded composite shape memory alloy components intended for follow-on experimental effort. A modular wing with 3-D printed components and other fabrication constraints is proposed. A computational model in a fluid-structure interaction framework is used to represent the response of a morphing trailing edge in a wind tunnel environment. A reduced-order constitutive model for a composite of Shape Memory Alloy (SMA) wires embedded in an elastomer matrix is considered in the computational model. The length of each actuator, the spar positions, and the shape of the baseline airfoil are optimized to morph the baseline airfoil to a bio-inspired airfoil taking into consideration the inner structure constraints.
