Aeroelastic Characteristics of Wing with Embedded Shape Memory Alloys

Shape memory alloys have the ability to change the structural and aeroelastic characteristics of wings greatly. They can produce high axial forces due to temperature changes. Temperature changes lead to transition between different phases of the shape memory alloy, which widely alter their mechanical properties. They recover their original shape with changing the temperature. Embedding shape memory wires into wings can greatly increase the flutter margin, while impose a minor weight on the system. Also, the amplitude of the limit cycle oscillations that cause fatigue of the wing will be reduced.
