Design Analysis of Two Ways Shape Memory Alloy (SMA) Actuated Aerofoil

Abstract:

This paper describes the design analysis of the behavior of a shape memory alloy (SMA) plate embedded into an aerofoil. Experimentation and simulation were done to fulfill this purpose. The aerofoil is made of silicone rubber material. The SMA plate which was embedded into the maximum chamber of aerofoil during the fabrication process was measured at approximately 175mm, 63mm and 3mm in length, width and thickness respectively. Experimentation was conducted to show that the SMA plate is able to produce two-way shape memory effect. Simulation was executed by using Abaqus 6.9-1 (finite element analysis software). The aerofoil profile was changed by the movement of SMA plate, which has subsequently changed the angle of aerofoil’s trailing edge. The result from the experiment shows that the aerofoil’s trailing edge has undergone a certain amount of displacement after heated. Upon cooling, the aerofoil’s trailing edge did not return to its initial position. Based on this analysis, it is clear that the simulation results are in agreement with the findings of experimental results.
