Abstract:
The present invention relates to a component (100) for a fluid flow engine, such as a gas turbine (100), comprising a first side (1), e.g. a top side and a second side (2), e.g. a bottom side, wherein the component (100) further comprises a mesh (5) of interior channels (20) for guiding a fluid through the component (100), wherein a fluid inlet being in fluid communication with channels (10) of the mesh (5) is provided at the first side (1) and at the second side (2), respectively, and wherein the mesh (5) is further arranged and configured such that channels (20) originating from the fluid inlet (10) of the first side (1) and channels (20) originating from the fluid inlet (10) of the second side (2) are interlaced such that a fluid entering the component (100) is at least partly guided according to opposing directions (FD) in the mesh (5).
Abstract:
Die Erfindung betrifft eine Schaufel (11) für eine Strömungskraftmaschine, beispielsweise eine Gasturbine oder eine Flugzeugturbine. Diese weist einen Innenraum (29) auf, durch den Kühlgas über Kanäle (25) an die Oberfläche (23) der Schaufel (11) transportiert werden kann. Hierdurch soll ein Film von Kühlgas auf der Oberfläche (23) ausgebildet werden, um die Schaufel (11) thermisch zu schützen. Erfindungsgemäß ist vorgesehen, dass es sich bei den Kanälen (25) um Mikrokanäle handelt, deren Querschnittsfläche kleiner als 0,8 mm 2 ist. Deswegen können vorteilhaft eine Vielzahl von Mikrokanälen (25) über die Oberfläche (23) der Schaufel (11) verteilt werden, wodurch sich zuverlässig ein geschlossener Kühlfilm auf der Schaufel ausbilden lässt. Um eine derartige Vielzahl von Mikrokanälen in der Schaufel zu verwirklichen, wird die Schaufel vorteilhaft mit einem additiven Fertigungsverfahren wie dem Laserschmelzen hergestellt, wobei dieses Verfahren ebenfalls Gegenstand der Erfindung ist.

The present invention relates to a gas turbine system comprising a burner arrangement having a tubular combustion chamber, a turbine and a transition duct (7) connecting the combustion chamber and the turbine, wherein the transition duct (7) is provided with an axially extending cooling air channel (11), wherein the transition duct (7) is provided with a plurality of axially extending cooling air channels (11), and wherein largely each cooling air channel (11) is provided with one single inlet opened to the outside of the transition duct (7) and with one single outlet opened to the inside of the transition duct (7).
Abstract:
A method of additively manufacturing is used to produce a component with an internal cooling channel for conveying a fluid. Powders in a powder bed are selectively fused to form a shaped layer of a body of the cooled component. The fusing is repeated on a layer-by-layer basis to form the body of the component with the internal cooling channel extending within the body, so that a peripheral wall of the internal cooling channel has a geometry that allows the peripheral wall to be self-supporting.
Abstract:
A cooling circuit for a gas turbine engine comprises a first wall having a first surface facing a first cavity and a second surface facing away from the first cavity. A second wall is spaced outwardly of the second surface of the first wall to provide at least one second cavity. Cooling fluid is configured to flow from the first cavity and exit to an external surface of the second wall via at least one hole to provide cooling to the external surface. A gas turbine engine and a method of forming a cooling circuit for a gas turbine engine are also disclosed.
Abstract:
A dust mitigation system for airfoils (32) includes a plurality of contoured tip turns (60, 62) which curve about at least two axes (A,B). This inhibits recirculation areas common within airfoils and furtherinhibits dust build up within the cooling flow path of the airfoil.
