Abstract
A device and a method are for producing a blade including two outer walls and at least one cavity between the outer walls, for a turbine. An outer mould and several cores are used in forming the outer walls and the at least one cavity of the blade. At least one of the cavities is divided into two channels by a middle segment. One channel is located between the first outer wall and the middle segment, while the other channel is located between the middle segment and the second outer wall. Two cores which are separate from each other are used accordingly. This provides a simple and economical means of reducing the thickness of the outer wall.
Claims18
A device for producing a turbine blade having two outer walls and at least one cavity, arranged between the outer walls, comprising:
- an outer mold and a plurality of cores for forming the outer walls and the at least one cavity, wherein each of the cores includes at least one section which extends from an associated outer wall up to a center web of the blade, without being involved in the formation of the other outer wall.
A method or producing a turbine blade having two outer walls and at least one cavity, arranged between the outer walls, comprising:
- an outer mold and a plurality of cores, provided for forming the outer walls and the at least one cavity, wherein at least one section of each core is supported in such a way that a distance between the outside of the section of the one core and the inside of the outer mold is independent of a distance between the outside of the section of the other core and the inside of the outer mold, so that the wall thicknesses of the two outer walls, at least in the region of the sections, are formed independently of one another.
A blade for a turbine, comprising:
- two outer walls and at least one cavity arranged between the outer walls, wherein at least one cavity is divided into two passages by a center web, the at least one passage being arranged between the at least one outer wall and the center web and the other passage being arranged between the center web and the other outer wall, wherein the wall thickness of the center web is greater than the wall thickness of the outer walls.
