Abstract (en)

Heating systems (200) for a rotor (114, 210) in-situ in a turbomachine (90, 190) are provided. In contrast to conventional systems that merely heat from an external turbine (212) casing, embodiments of the disclosure heat the rotor (114, 210). In one embodiment, a heating system (200) includes a heating element (430) to heat a portion of an exterior surface (240) of the rotor (114, 210). In another embodiment, the heating system (200) may include a heating elements (330, 430, 530) at least partially positioned within the rotor (114, 210), and the rotor (114, 210) including the heating system (200). Each embodiment may include a controller (340) to control operation of the heating elements (330, 430, 530).
