摘要： The invention relates to a method for producing a cast part of a thermal turbo-machine by way of a known casting process. Between a model mold and a ceramic insert, projections are located on the ceramic insert, whereby the projections have an angle (&agr;, &bgr;) between the center line and the outer edge of the projections of less than 30°, and whereby the projections are used both for the fixation of the insert during the casting process and for the reduction of the notch factor inside the recesses created in the cast part.

摘要： The temperature can nowadays be reduced by about 400° C. as a result of the cooling of the guide vane (15) of the first guide wheel. The many film bores leading outward from the guide vane (15) must therefore remain free of blockages or deposits caused by suspended matter in the cooling medium. Only pure gas must therefore be used as the cooling medium for the first guide wheel. This purpose is served by a dust separator which is designed advantageously as an axial cyclone (24, 24′). The latter has no moving structural parts, has a simple design, is therefore insusceptible to faults and can be exposed to high temperatures. The axial cyclone is a centrifugal deduster without gas stream reversal.

摘要： In a hollow-cast component, a core opening (13) created during manufacturing is closed with a closure piece (14). This closure piece is located inside a recess (15) in the component, whereby the recess is arranged so that it is imbedded completely in the cast material, and completely covers the core opening. Because of this installation, the closure piece is fixed in a form-fitting manner in the direction of two spatial axes, so that the closure piece only needs to be secured with an additional joint in the installation direction. It is preferred that the installation direction is normal in relation to the direction of maximal stress of the closure piece, so that a joint is subject to a relatively small stress and therefore can be produced with little expenditure and a high degree of operational safety.

摘要： A cooling wall comprises an outer surface, which is exposed to a hot-gas flow, an inner surface, and at least one film-cooling hole within the wall, which film-cooling hole has a diffuser section and an outlet at the outer surface. The diffuser section has first and second internal surfaces, the intersection edge between the first internal surface and the outer surface forming an upstream edge of the outlet, and the intersection edge between the second internal surface and the outer surface forming a downstream edge of the outlet. The diffuser section has side surfaces, which faces one another, connect the first and second internal surfaces and diverge from one another toward the outlet of the diffuser section. The first internal surface of the diffuser section is rounded toward the axis of the film-cooling hole.

摘要： In a combustion chamber, a gaseous or liquid fuel is injected as a secondary flow into a gaseous, channelized main flow. The main flow is directed to pass over a plurality of vortex generators (9) arranged side by side over the width or circumference of the channel (20) through which the flow passes. The height (h) of the vortex generators is at least 50% of the height (H) of the channel through which the flow passes or of that part of the channel associated with the vortex generators. The secondary flow is introduced into the channel (20) in the immediate vicinity of the vortex generators (9). Longitudinal vortices without any recirculation region are produced in the channel through which the flow passes by means of the new static mixer. Extraordinarily short mixing distances, with a low pressure loss at the same time, are thus achieved in a combustion chamber according to the invention.

摘要： A sealing arrangement between two radially adjoining components of an assembly that rotates during operation, in particular between the rotor and the rotating blade of a gas turbine component includes a sealing element in a depression of an inner one of the two components at the boundary surface to the outer one of the two components. The sealing element is designed in such a way that it does not or does only slightly project beyond the depression during assembly and that, during rotation of the assembly, the centrifugal force acting on it produces a sealing joint between the components. The present sealing arrangement permits an easy installation of rotating blades to the rotor of a gas turbine.

摘要： A method is disclosed for reducing the variance in the coolant consumption of components of a turbo-machine, in particular a gas turbine. The components are provided with one or more holes for the passage of a coolant, wherein a surface roughness existing inside the holes is reduced by mechanical finishing. The method is characterized by mechanical finishing that is performed by reshaping rough points that cause the surface roughness using a cold working process such as at least one of beating, pressing and rolling. The method permits a simple reduction of the surface roughness without creating finishing residues that could result in obstructions of the holes.
