Definitions
- Turbine blade having coolant channel and the outlet
- the invention relates to a turbine blade with a blade root and a blade body, in which extends starting from an entry point at least one radial coolant ⁇ channel up to an end point of the cooling channel.
- An often used in gas turbines cooling medium is air. Part of the compressed air is taken in the compressor and fed to the gas turbine blades, bypassing the combustion chamber.
- the cooling air is supplied to the turbine blade in one or more cooling channels extending from the blade root in the blade body to an end point of the cooling channel, to which an opening in a surface of the airfoil is arranged, through which the entire guided in the coolant passage cooling air this point is omitted for cooling the turbine blade.
- a uniform cooling of the turbine blade is possible with such a design only when a large number of cooling channels are driven through the blade body, which then could possibly affect the strength of the turbine blade in large numbers.
- a turbine blade according to the invention with a sight ⁇ felfuß and a blade has in the blade interior at least one non-cooled cavity, whereby, starting from an element located at the blade root entry point we ⁇ iquess a radial coolant passage in a blade body of the turbine blade up to an end point of the cooling ⁇ center channel extends, wherein the respective coolant channel is formed as a drilled blind hole and at least two outlet channels are provided, which connect the coolant channel for conducting coolant to a respective outlet opening on an outer wall of the airfoil.
- both a front side and on egg ⁇ ner back side of the airfoil is arranged in each case at least one outlet which is connected by means of an outlet channel to the coolant channel. This allows bilateral cooling of the airfoil, starting from a single coolant channel.
- the airfoil arranged a plurality of outlet openings, which are each connected by means of an outlet channel with thedemit ⁇ telkanal.
- the outlet channels are formed with a significantly klei ⁇ lower cross-sectional diameter than the coolant channel, in particular with a diameter ratio of 1: 5, 1:10 or higher.
- the outlet channel / outlet channels are formed as through-holes. A drilled execution of the coolant channel and / or the off ⁇ let channels allows an easy and cheap production of the turbine blade and in particular its cooling system.
- the coolant channel can, however, also by means of electrical discharge machining (EDM, in German:
- spark erosive machining This may allow a greater depth of the coolant channel at ⁇ play, in larger turbine blades.
- a plurality of coolant channels are arranged in the blade body, in particular two, three, five, ten or a larger plurality.
- each of these has coolant channels we ⁇ tendonss an outlet port, particularly preferably Wenig ⁇ least two or more outlet channels on.
- the end points of at least two of these coolant channels are arranged at different radial positions of the turbine blade, in particular with respect to a radial axis of the turbine blade.
- the coolant channels each have an outlet region, in which a A plurality of outlet channels, in particular all outlet channels, emanating from the coolant channel.
- the outlet region is preferably limited to a specific radial section of the turbine blade ⁇ .
- This embodiment allows for a certain order of certain radial sections of the turbine blade to certain coolant channels.
- a proportion of cooling air for a particular radial section of the turbine blade can be controlled.
- the outlet regions of at least two of these coolant channels are arranged at different radial positions of the turbine blade in order to allow the most uniform possible cooling (based on the conditions of use).
- Figure 1 in a partially sectioned oblique view a
- Turbine blade according to an embodiment of the invention.
- Figure 2 in a partially sectioned oblique view of a section of a turbine blade according to ei ⁇ ner further embodiment of the invention.
- the airfoil 4 for weight reduction comprises three cavities 5, which have no connection to a coolant source and thus are not flowed through by the coolant. Thus, these cavities are not used for blade cooling and are thus uncooled.
- a bucket body 6 of the turbine blade 1 extend next to it and starting from in each case one entry point 8.1, 8.2 and 8.3, three coolant channels 10.
- the firstdemit ⁇ telkanal 10.1 is arranged in the front edge of the airfoil.
- the remaining two coolant channels 10.2 and 10.3 are arranged in those ribs 7, which form between the uncooled cavities and connect the side walls of the airfoil together.
- the coolant channels 10. 1, 10. 2 and 10. 3 run in an at least substantially radial direction as far as an end point 12 of the respective coolant channel 10.
- the coolant channels 10.1 and 10.2 extend from a - information on any one transverse direction of the blade root 2 central entry point - the way up to their end points 12.
- the coolant ⁇ channel 10.3 is located laterally away from the center of the blade root 2, and therefore follows the shape of the airfoil 4 in the radially inner region of the airfoil 4 at this axial position.
- each of the cooling channels 10 a plurality of outlet channels 16 and 18 are arranged, wherein the outlet channels 16 respectively open at an outlet opening 20 in the outer wall 22 of the turbine blade, and thus connect the cooling channel 10 with these outlet openings 20.
- the outlet channels 16 open onto a front side 24 of the airfoil 4, the outlet channels 18 open into not shown ⁇ outlet openings on the back of the turbine rotor blade first
- thedeschka ⁇ channels 8 have different cross-sectional diameters xi, X2 and X3, which allow the provision of different cooling air flows.
- cooling air is introduced into the coolant channels 10, which then distributed in the outlet 14 in the individual outlet channels 16 and 18 and exits at the outlet openings 20 ⁇ .
- the cooling air can selectively the environment the off ⁇ let cool openings by the relatively cold
- Cooling air cools the relatively hot outer wall 24 of the turbine ⁇ bucket.
- FIG. 2 shows a turbine blade 1, in which by means of two exemplary coolant channels 10. 1 and 10. 2 it is illustrated how different regions with respect to the radial axis R of the turbine blade 1 can be supplied with cooling air through different coolant channels.
- the coolant channel 10.1 extending from its entry point 8.1 ⁇ back up to its end point 12.1 (at the radial posi tion of the end point ⁇ 12.1 is the representation of the shovel blade 4 cut).
- the cooling channel 10.2 is slightly offset from thedemit ⁇ telkanal 10.1 arranged in the flow ⁇ direction of the working fluid.
- the coolant channel 10.2 is shorter, so that the distance between the end point 12.2 and the entry point 8.2 is smaller than the distance between the end point 12.1 and the entry point 8.1.
- Both cooling channels have an off ⁇ passband 14, wherein the outlet 14.1 of the first Cooling channel 10.1 is disposed at a radial position which is farther outward than the radial position of the outlet portion 14.2 of the second coolant channel 10.2.
- the outlet openings 20.1, at which by the connection with the cooling channel 10.1 by means of the outlet channels 16.1 cooling air can flow in the direction of arrow, arranged radially further outward than the outlet openings 20.2 of the second cooling channel 10.2.
- the cooling mechanism according to this embodiment is due to the possibility of both the coolant channels 10 and the ⁇ lasskanäle 16 and 18 straight form - and thus as Boh ⁇ ments to produce - manufacturing technology relatively simple and thus inexpensive to manufacture.
