Beschreibung
Zusammenfassung:	A rotor of a gas turbine includes a rotating body with a platform with rotor blades arranged thereon, at least one turbine blade, the platform of the rotating body having first and second sections oriented at a respective angle of attack with respect to the engine longitudinal axis. The respective rotor blades are subject to crack growth in the state in which they are installed as intended into an engine, a respective crack spreading from a leading edge of the turbine blade as far as a predefined axial fracture crack length, at which blade fracture occurs. The first section has a smaller angle of attack than the second section, the first section extending from a leading edge of the platform as far as the axial fracture crack length. Moreover, the disclosure relates to a method for producing a rotor.
