<p>A gas turbine comprising an array of rotor blades (15) arranged around a rotation axis (A), a guide ring (23) arranged around the rotor blades (15), and a cooling circuit (25), configured to receive an air flowrate and to direct the air flowrate to the rotor blades (15). The guide ring (23) has through holes (27) coupled to the cooling circuit (25) and configured so that air coming from the cooling circuit (25) and passing through the holes (27) deviates from an inner surface (23a) of the guide ring (23) and forms jets (G) directed towards tip sections (20) of the rotor blades (15) and having an output speed from the holes (27) so as to reach the tip sections (20) of the rotor blades (IS).</p> |
