Abstract: Actuators utilising shape memory alloy materials are known with regard to gas turbine engines. Such shape memory alloys have been used with respect to deformation provided in vanes and blades as well as nozzle elements in order that variations can be made in engine configuration dependent upon thermal cycling. Unfortunately, pedestals in order to provide spacing between the shape memory alloy and an antagonistic bias has resulted in uneven stress distribution as well as a higher thermal mass for the shape memory alloy. An uneven stress distribution will limit operational life whilst a higher thermal mass will result in slower reaction times. By separation of the shape memory alloy or material from its antagonistic bias through use of a slide element, a reduction in thermal mass is achieved and, more importantly, stress differentiation across the actuator is reduced.

Abstract translation: 使用形状记忆合金材料的致动器关于燃气涡轮发动机是已知的。 已经使用这样的形状记忆合金关于在叶片和叶片以及喷嘴元件中提供的变形，以便根据热循环可以在发动机配置中进行变化。 不幸的是，为了在形状记忆合金和拮抗性偏压之间提供间隔，基座已经导致形状记忆合金的应力分布不均匀和较高的热质量。 不均匀的应力分布将限制使用寿命，而较高的热质量将导致较慢的反应时间。 通过使用滑动元件将形状记忆合金或材料与其拮抗性偏压分离，实现了热质量的降低，更重要的是减少了致动器的应力分化。
