ABSTRACT:
A turbomachine seal for reducing fluid flow through the gap between circumferentially adjacent blade platforms is disclosed. The seal comprises a pair of radially inwardly extending elastomeric members. Each member has an inwardly extending first face and is bonded at a second face to respective ones of adjacent platforms. Each elastomeric member is circumferentially deflectable under a centrifugal load so that respective first faces meet.
