Abstract: A turbomachine has at least one stator (4) and at least one downstream rotor (7), with the stator (4) being provided with stationary stator blades and the rotor (7) comprising several rotor blades attached to a rotating shaft. A casing (2) confines the passage of fluid through the rotor (7) and the stator (4) in the outward direction. A mechanism for peripheral jet creation is provided in the area of at least one vane of the stator (4), with at least one nozzle (21) issuing fluid at the radially outer boundary of a main flow path.

Abstract: A turbomachine blade is repaired by making a leading edge cutback between two points (A) and (E) where point (A) lies within a range of relative blade height (h/H) of 0?(h/H)point A<0.85, and point (E) lies within a range of 0.95<(h/H)point E?1.0, with (h) being a blade height coordinate which originates at an end of the blade closer to starting point (A), and (H) being the blade height. A cutback trace is defined by (s/SAE) and (c/Cm), with (c) being a local cutback length in meridional flow direction, (Cm) being a meridional chord length, (s) being a local cutback length in radial direction, and (SAE) being a radial cutback length, where (c) gradually increases from point (A) to its maximum at 0.60<s/SAE<0.95, with (c/Cm) there being ?0.25, and then decreasing to ?0.05.
