A shape-controlled airfoil was developed by the use of shape memory alloys (SMA). The developed airfoil consisted of the leading and trailing parts, between which the SMA rods were inserted. While the trailing part was fixed on the wall of the test section in the wind tunnel, the leading part could be turned about 9 the SMA. The two way change in the blade shape was realized by the use of a differential two way element in which the two different shapes were memorized. The developed airfoil was tested in the wind tunnel in order to check the effect of the shape change on the characteristics of the airfoil. The flow visualization experiments in the smoke tunnel showed that th e shape change by an electrically heated SMA produced a marked change in flow around the airfoil near the stall angle of the original shape. Moreover, the traverse of the wake behind the airfoil also exhibited the effect of the shape change in the airfoil. As a result of this study, it was found that the developed SMA actuator was effective for the control of flow separation from the blade surface. And it is suggested that the SMA actuator can be applied to the turbomachinery as an active control for the airfoil.

通过使用形状记忆合金（SMA）开发了形状控制翼型。开发的翼型由前部和尾部组成，SMA 杆插在前部和尾部之间。当尾部固定在风洞测试部分的壁上时，前部可以转动约9°SMA。叶片形状的双向变化是通过使用可记忆两种不同形状的差分双向元件来实现的。所开发的翼型在风洞中进行了测试，以检查形状变化对翼型特性的影响。烟道中的流动可视化实验表明，电加热 SMA 的形状变化在原始形状失速角附近的翼型周围产生了显着的流动变化。此外，翼型后尾流的横移也表现出翼型形状变化的影响。这项研究的结果是，我们发现所开发的 SMA 执行器对于控制叶片表面的流动分离是有效的。建议将SMA执行器应用于涡轮机械作为翼型的主动控制。
