This Small Business Innovation Research Phase I project will development a smart seal using shape memory alloy technology (SMA) combined with elastic foundation bedding. The use of active control allows corrections to take place during the operation. Active control protects against seal failure and preserves the tribological characteristics. The objective is to develop a class of non-contacting mechanical annular seals (e.g. labyrinth, smooth bushing, and step) where their clearance can be actively controlled.The commercial benefits from this application will be in compressors and steam/gas turbines. This project will have a significant advantage over existing types of labyrinth seals by reducing the leakage rates, extending operational life, decreasing required maintenance, decreasing fuel consumption or electric power of the machinery and will lessen contamination of the environment.

这个小型企业创新研究第一阶段项目将开发一种智能密封，使用形状记忆合金技术（SMA）结合弹性基础垫层。主动控制的使用允许在操作期间进行校正。 主动控制可防止密封失效并保持摩擦学特性。目的是开发一类间隙可以主动控制的非接触式机械环形密封（例如迷宫式、光滑衬套和台阶式）。这种应用的商业效益将在压缩机和蒸汽/燃气轮机中实现。该项目将通过降低泄漏率、延长使用寿命、减少所需的维护、降低燃料消耗或机器的电力以及减少对环境的污染而比现有类型的迷宫式密封具有显著的优势。
