Abstract (en)
[origin: EP2543851A1] A gas turbine engine (1) comprises a hollow rotor (11) including a plurality of rotor segments stacked and coupled together in a direction of its center axis (C) and defining at least one of a compressor (3) and a turbine (7); and a pipe unit (51) inserted into an inner space (29) of the rotor in the center axis direction. In the gas turbine engine (1), a weight distribution of the pipe unit (51) within an axial transverse section is set eccentric with respect to the center axis (C) of the rotor. In this way, a gas turbine engine which is high in performance and reliability is provided, in which a pipe provided in an inner space of the rotor to transport a cooling medium or lay out a cable, etc., is prevented from whirling.
