Abstract (en)
[origin: EP1489266A1] A blade (1) is held in a peripheral groove (7) of a disk (12). The blade has a platform (30) whose radially-outer face (30a) defines boundary of a gas flow stream and whose radially-inner face (30b) has upstream and downstream ribs (32,33). The ribs are arranged near upstream and downstream gasket-accommodation grooves (20,21). Thickness of downstream rib in axial direction is greater than that of upstream groove.
