Zusammenfassung:	The device has a turbine shaft with adjacent plates (3-5) carrying blades (14,15) attached in a star formation and cooled by at least one coolant passing through coolant channels inside the blades. Several hollow volumes (8,9,20,23) formed between two immediately adjacent plates in the radial direction each enclose the shaft in the peripheral direction and contain coolant at different pressures that can flow into and out of the hollow volumes. Independent claims are also included for the following: (a) a method of cooling a gas turbine engine (b) and a method of cooling rotor blades in a gas turbine engine.
