PLATFORM SEAL IN A TURBOMACHINE ROTOR, METHOD FOR IMPROVING THE SEAL BETWEEN A PLATFORM AND A TURBOMACHINE BLADE

摘要

An elastomer material seal for an interleaved platform between two adjacent blades in a turbomachine rotor is disclosed. The seal is of elongate shape and includes transversely a contact part, an attachment part, and a flexible part between the attachment part and the contact part. The seal is noteworthy in that it further includes a local reinforcement of the flexible part, to avoid the tearing that would result from centrifugal forces on the seal. The local reinforcement of the flexible part includes at least one transverse rib on the flexible part.
