Abstract
Disclosed is a non-contacting seal arrangement, an electromechanical system having a non-contacting seal arrangement, and a process of fabricating a non-contacting seal arrangement. The non-contacting seal arrangement includes a shape-memory alloy portion, a non-contacting seal, and an ingress gap. The ingress gap is between the non-contacting seal and the shape-memory alloy portion, between a surface of an electromechanical system and the non-contacting seal, or between the surface of the electromechanical system and the shape-memory alloy. An increase in temperature expands the non-contacting seal and the shape-memory alloy portion substantially maintains the ingress gap. The electromechanical system includes a rotating component and a surface extending around at least a portion of the rotating component and forming the ingress gap. The process includes securing the shape-memory alloy portion, securing the non-contacting seal, and forming the ingress gap.
