Abstract
Turbomachine, in particular a compressor of a gas turbine, having rotor blades (,) and guide vanes (,), in which individual or all guide vanes (,) are configured as cooled vanes. The cooled vanes (,) have air guidance ducts (,) which emerge into outlet openings (,) in the region of the vane tips (,). Cooling air (K) is ejected through the outlet openings (,) and impinges at high velocity onto a rotor shaft (,). The cooling effect which can be achieved by this means is optimal and, in addition, leads to a raising of the compressor efficiency and the surge line.
