摘要： A coolable blade (10) essentially comprises a blade root (11) and a blade body (1), which is composed of a pressure-side wall (6) and a suction-side wall (5). They are connected to one another essentially via a trailing-edge region (4) and a leading-edge region (3) in such a way that at least one hollow space (2) used as a cooling-fluid passage is formed. An essentially radially running, diverging cooling passage (7) is arranged in the trailing-edge region (4).

摘要： A thermally highly loaded machine component (10), which is protected from overheating by film cooling, is provided with conical cooling passages (30) of circular cross section. The cooling passages are designed so as to be divergent from the cold-gas side (13) toward the hot-gas side. The conical cooling passages, as compared with cylindrical passages with regard to the mass flow of cooling medium (35) fed through the cooling passages, are substantially less dependent on the pressure ratio between the cold-gas side (13) and hot-gas side (14) of the component. The straight conical cooling passages of round cross section throughout may be produced in a very simple manner by laser drilling, with a convergent cutting beam being used for the machining.

摘要： A device separates foreign particles from cooling air fed to turbine rotor blades. The cooling air is fed directly or indirectly via stationary nozzle units to an annular space between wall parts of a turbine stator and rotating wheel disk as a cooling-air stream in the circumferential direction. The annular space communicates with ducts, arranged in the disk, for feeding the cooling air into the blades. A diverter unit is provided inside the annular space or so as to delimit the annular space on one side, so cooling air emerging from the nozzle units, before entering the ducts, is diverted on one side and foreign particles are centrifugally thrown into a radially outer part of the annular space and separated therefrom with a barrier-air fraction. The diverter unit has a surface region on which the stream impinges so it can be diverted radially outward through an angle greater than 90°.

摘要： Turbomachine, in particular a compressor of a gas turbine, having rotor blades (11) and guide vanes (12), in which individual or all guide vanes (12) are configured as cooled vanes. The cooled vanes (12) have air guidance ducts (13) which emerge into outlet openings (14) in the region of the vane tips (15). Cooling air (K) is ejected through the outlet openings (14) and impinges at high velocity onto a rotor shaft (18). 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.

摘要： An apparatus and a process are provided for impingement cooling of a component exposed to heat in a flow machine. The component includes a wall section on at least one side of which at least one impingement air flow impinges, the air flow passing through a flow channel within a surface element arranged spaced apart from the wall section and striking against the wall section to be cooled. The flow channel has an inlet aperture and an outlet aperture, with the outlet aperture directly facing toward the wall section to be cooled, and the inlet aperture has a throughflow cross section which is smaller than the throughflow cross section of the outlet aperture.

摘要： An arrangement for cooling a flow-passage wall surrounding a flow passage is described, having at least one rib element which induces flow vortices in a flow medium passing through the flow passage, is attached to that side of the flow-passage wall which faces the flow passage, and the shape and size of which are selected in accordance with a certain heat transfer coefficient and a certain pressure loss caused in the flow medium due to the latter flowing over the rib element. The invention is characterized in that the rib element, while largely retaining its original shape and/or size, has contours enlarging its surface facing the flow passage.

摘要： A cooling passage of a component subjected to high thermal loading, which is formed as a cavity (2, 20, 30), running in a longitudinal direction (L) and curved orthogonally to the longitudinal direction (L), between a first wall (5) and a second wall (6), which in each case are connected to one another in a laterally adjacent manner, which has ribs (7, 17, 27), which are arranged on the first wall (5) and the second wall (6) such that they alternate in a longitudinal direction (L) and are staggered relative one another and, at least in sections, assume a non-orthogonal angle relative to a projected center axis (10′), and through which a cooling fluid (K) can flow in a longitudinal direction (L), in which case, when the profile of the cavity (2, 20, 30) is curved orthogonally to the longitudinal direction (L), the ribs (7, 17, 27) are formed in such a way that, in each case locally with regard to the adjacent rib of the opposite wall, they maintain a distance (a) which is half a respective local rib spacing (p). It is thereby possible to even out the heat transfer at a curved passage profile.
