Abstract (en)
[origin: WO2019202234A1] A turbine ring assembly comprises a plurality of adjacent ring sectors (10) forming a turbine ring (1), each ring sector (10) having a platform (12) with an inner face defining the inner face of the turbine ring (1) and an outer face from which an upstream lug (14) and a downstream lug (16) extend in the radial direction. Each ring sector (10) comprises a first groove (41) present in the platform (12) in the vicinity of the inner face (12a) of said platform, a second groove (40) present in the platform (12) in the vicinity of the outer face (12b) of said platform, an upstream groove (42) extending into the upstream lug (14) and a downstream groove (43) extending into the downstream lug (16). A first sealing tab (21) extends in the first groove (41). A second sealing tab (20) extends in the second groove (40). An upstream sealing tab (22) extends in the upstream groove (42). A downstream sealing tab (23) extends in the downstream groove (43). The second sealing tab (20) comprises one or more openings (26, 27).
