Abstract
A sealing assembly () for a turbine engine comprising a first element () and a second element (), the first and second elements () being concentric and in relative rotational movement with respect to each other about an axis of rotation (X), the sealing assembly () comprising at least one first wiper () and an abradable member (), the first wiper () being annular in shape and carried by the first element (), the first wiper () extending radially towards the abradable member () and continuously around the axis of rotation (X), the abradable member () being annular in shape and carried by the second element (), the abradable member () extending tangentially opposite the first wiper (), the first wiper () comprising primary angular portions (), each extending tangentially along a primary angular sector ('), the primary angular portions () each having, in cross-section, a first constant profile, characterised in that the first wiper () comprises secondary angular portions () each extending tangentially along a secondary angular sector (′), the secondary angular portions () each having, in cross-section, a second profile different from the first profile, the number of secondary angular portions () being equal to the number of primary angular portions (), the secondary angular portions () being interposed between the primary angular portions ().
