A sealing arrangement for a rotor of a turbomachine includes a blade (), a heat shield () and a sealing element () for sealing between the blade () and the heat shield () when the blade (), heat shield () and sealing element () are assembled for use in the rotor. The heat shield () includes a first slot () for accommodating a first member () of the sealing element (), and a root portion of the blade () includes a second and third slot () for accommodating a second member () of the sealing element (). The first slot () extends in a direction which is substantially mutually perpendicular to a direction in which the second and third slot () extends, and the first member () extends in a direction which is substantially mutually perpendicular to a direction in which the second member () extends.

Sealing arrangement for a rotor of a turbo machine

A gas turbine arrangement with heat accumulation segments () which are arranged, opposite moving blades, on a casing of the gas turbine, and with guide vanes () which are arranged adjacently to the heat accumulation segments () over the circumference between the casing of the gas turbine and the rotor, the moving blades and the guide vanes () being arranged in a hot-gas duct () of the gas turbine. At least one sealing element () arranged over the circumference is present between the guide vanes () and the heat accumulation segments () and can be separated from the hot-gas duct () by means of a protective shield ().

Gas turbine arrangement

A gap seal in a gas turbine for sealing off a cooling space, formed between a heat shield and a heat shield carrier, from a hot gas space of the gas turbine. A sealing body is retained in a movable manner on the heat shield, on the one hand, and on a blade carrier, on the other hand, adjacent to the heat shield carrier.
