More Information
Summary:A sealing arrangement for a rotor of a turbomachine includes a blade ( 2 ), a heat shield ( 3, 4 ) and a sealing element ( 5, 6 ) for sealing between the blade ( 2 ) and the 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 ) includes 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 ) includes 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.
