Abstract: A gas turbine is provided that includes a rotor which is rotatable around an axis and equipped with rotor blades, and which is concentrically enclosed at a distance by a casing, which is equipped with stator blades, forming an annular hot gas passage. Rings with stator blades and rotor blades are arranged in a manner alternating in the axial direction. Between adjacent stator blades, heat shield segments are arranged, which delimit the hot gas passage on the outside in a region of the rotor blades and are cooled by impingement cooling where a cooling medium from an outer annular cavity flows into the heat shield segment.

Abstract: A cooled component for a gas turbine is disclosed, which by an outer side of a wall delimits hot gas passage of the gas turbine and on an inner side has a device for impingement cooling. The impingement cooling device can include a multiplicity of impingement cooling chambers which are arranged next to each other, operate in parallel, are covered by impingement cooling plates which are equipped with impingement cooling holes, and are impinged upon by cooling air during operation.

Abstract: A continuous-flow machine (1), in particular a turbine or a compressor, includes at least one stator blade section (2) which has a plurality of stator blades (3) which project into a gas path (10) of a working gas, and at least one adjacent section (6), which has a plurality of adjacent elements (7), which bound the working gas path (10) at the side. A gap (11), through which a cooling gas can be introduced into the working gas path (10), is formed between the stator blades (3) of the stator blade section (2) and the adjacent elements (7) of the adjacent section (6). In order to improve the efficiency of the continuous-flow machine (1), lateral seals (14) are formed in the gap (11) and prevent or at least impede pressure equalization and/or a gas flow in the gap (11) in the lateral direction (5).
