SEALING ARRANGEMENT FOR A ROTOR OF A TURBOMACHINE

摘要

A sealing arrangement for a rotor of a turbomachine comprises a blade (2), a heat shield (3, 4) and a sealing element (5, 6) for sealing between the said blade (2) and the said heat shield (3, 4) when the blade (2), heat shield (3, 4) and sealing element (5, 6) are assembled for use in the rotor. The heat shield (3, 4) comprises a first slot (7, 8) for accommodating a first member (11, 12) of the sealing element (5, 6) and a root portion of the blade (2) comprises a second and third slot (9, 10) for accommodating a second member (13, 14) of the sealing element (5, 6). The first slot (7, 8) extends in a direction which is substantially mutually perpendicular to a direction in which the second and third slot (9) extends, and the first member (11, 12) extends in a direction which is substantially mutually perpendicular to a direction in which the second member (13, 14) extends.
