Zusammenfassung:	The turbine (12) for a turbine engine (100) extends around a major axis (X-X) and comprises: -a casing (4) comprising an annular hook (38), -a movably mounted impeller (16), -a ring (30) extending opposite the impeller in a direction radial to the major axis (XX), -a distributor (14) comprising a blade provided with a platform (11), the platform being extended radially outwards by a spoiler (22, 24), the spoiler (22, 24) being radially mounted on the hook (38), and -foils (40) each having a profiled trough shape in a direction circumferential to the axis, the foils extending in succession in the circumferential direction, each foil (40) extending between the spoiler (22, 24) and the hook (38). The turbine comprises stops (162) to prevent the foils (40) from moving in the circumferential direction. Each foil (40) comprises a protrusion (162) arranged so as to extend circumferentially opposite another protrusion (162) of another adjacent foil (40).
