Abstract

The invention relates to a rotor () for a turbo machine, in particular for an aircraft turbine, with rotating blades () that are joined to a basic rotor body (), whereby at least one channel () extending between the high-pressure side (HD) and the low-pressure side (ND) of rotor () radially underneath a blade platform () of at least one rotating blade () is provided, whereby a slope of a principal axis of extension (H) of channel () relative to an axis of rotation (D) of rotor () has the same sign as a slope of a principal axis of extension (R) of a radially inner boundary of the flow channel of rotor. In addition, the invention relates to a turbo machine having a rotor () as well as to a method for manufacturing a rotor () for a turbo machine.
