Abstract

An apparatus for sealing a circumferential gap between a stationary component and a rotating member (303) is disclosed. The rotating member (303) is configured to rotate about a longitudinal axis (X-X') and has a radially outer surface (368) disposed at a first non-zero angle (370) with respect to the longitudinal axis (X-X'). The apparatus includes a stator disposed circumferentially about the longitudinal axis (X-X') and a shoe (204; 304; 404a) configured for translation in a radial direction with respect to the stator. The shoe (204; 304; 404a, 404b) includes a circumferential surface (364) and a plurality of protrusions (366; 466a, 466b) extending radially inward from the circumferential surface (364)toward the rotating member (303), each one of the plurality of protrusions (366; 466a, 466b) having a length configured to maintain a clearance gap (469a, 469b) with respect to the rotating member (303).
