Special Issue Information

Dear Colleagues

Since the invention of shape memory alloys (SMAs), in particular, NiTi based SMAs in the 1970s, we have seen extensive R&D in various types of actuators based on bulk and/or thin-film SMA elements. Recent developments in fatigue-resistance and temperature-insensitive versions provide more opportunities for SMAs in a wider range of applications. Furthermore, additive manufacturing of SMA elements enables rapid customization for individuals.

This Special Issue of Actuators, entitled Shape Memory Alloy Actuators, is a platform to showcase the achievements so far. Both review and original technical (including both experimental and modeling) papers are welcome.

A smart structure to actuate a morphing trailing edge based on the super critical airfoil NASA sc-0714(2) was designed and verified in a transonic wind tunnel. The pressure distribution over the wing was measured to evaluate the structure ability and effects of trailing edge deflections on the aerodynamic characteristics. In the experiment, Mach number was from 0.4 to 0.8, and the angle of attack was from 0° to 6°. The results showed that the smart structure based on shape memory alloy could carry aerodynamic loads under transonic flow and deflect the trailing edge. When the driving force was constant, deformation would be influenced by the Mach number and angle of attack. Increasing the Mach number weakened the actuation capability of the smart structure, which decreased the deflection angle and rate of the trailing edge. The influence of the angle of attack is more complex, and couples with the influence of the Mach number. The higher the Mach number, the stronger the influence of the angles of attack. Additionally, the trailing edge deflection would dramatically change the flow structure over the airfoil, such as the shock wave position and strength. If separation was caused by the trailing edge deflection, the limitation of the smart structure would be further found. Full article
