Intake surface for rotor of turbo machine, particularly gas turbine, has profiled upper surface, which has multiple elongated, axially running recesses at distance from one another

摘要

The intake surface (10) has a profiled upper surface (12), which has multiple elongated, axially running recesses (14) at a distance from one another. The intake surface has a base (18), which has recesses extended in axial direction differently into the intake surface. An independent claim is also included for a turbo machine, particularly gas turbine.
