An additive manufactured article for a gas turbine having a body with two lateral surfaces elongated in a first direction; at least a nested duct housed within the lateral surfaces and elongated in the first direction; a structure so that the nested duct is structurally connected to an attachment within the lateral surfaces, wherein at least the body, the duct and the structure are manufactured by an additive manufacturing process and the structure includes an array of ribs attached to the duct in order to compensate differential elongation along the first direction of the duct with respect to the attachment of the ribs by flexural deformation.

A combustor includes a combustor shell, an inner liner disposed inside the combustor shell and having an inner surface defining a cavity configured to receive hot combustion gases from a combustion chamber of the combustor, and an outer surface, the combustor shell and the inner liner defining an annular flow channel therebetween, and a segment carrier operatively connected to the inner liner and operative to receive an upper portion of the inner liner, the segment carrier and the inner liner defining a purging cavity therebetween. The inner liner includes a plurality of impingement jet holes configured to direct a flow of cooling air from the annular flow channel to the purging cavity.

A fuel injector device includes a body having a leading edge and a trailing edge and defining a streamwise direction from the leading edge to the trailing edge. The fuel injector device body includes a first surface and a second surface opposite the first surface, each surface extending between and including the leading edge and the trailing edge, and the surfaces conjoining each other at the leading edge and the trailing edge. The trailing edge, when seen in the streamwise direction, undulates along a trailing edge mean line and, along its extent, deviates in opposite directions from the mean line and includes at least one inflection point along its extent.

Fuel injector device

Disclosed is a fuel injector device having a body with a leading edge and a trailing edge and defining a streamwise direction from the leading edge to the trailing edge, the fuel injector device body having a first wall and a second wall opposite the first wall, each wall extending between and including the leading edge and the trailing edge and the walls conjoining each other at the leading edge and the trailing edge, each wall having a streamwise extent and a crosswise extent, the walls further enclosing an internal space, at least one fluid plenum being provided within the internal space, the fluid plenum at least at one of an upstream end and/or a downstream end being delimited by an internal wall structure, wherein at least one surface of the wall structure is an inclined surface which forms an angle with the streamwise direction which is smaller than or equal to a maximum angle, wherein the maximum angle is 60&#xb0;.
