Beschreibung
Zusammenfassung:	Gas turbine unit having an axis (A) parallel to the main gas flow (M), the gas turbine unit comprising: - a blade (1) having a tip (2); - a stator heat shield (3) having an inner surface (4) facing the blade tip (2); wherein the inner surface (4) of the stator heat shield (3) and the blade tip (2) define a variable clearance depending on the applied thermal condition; wherein the blade tip (2) is configured to have a cylindrical shape along the axial direction in a hot running condition starting from a conical shape along the axial direction in a cold starting condition.
