The present invention relates to a method for producing an engine component having a cooling duct arrangement which has a plurality of cooling ducts, each having an inflow opening, the inflow openings being arranged according to a predefined pattern in an inflow surface of the engine component, and each cooling duct opening into a recess in a wall of the engine component, along which wall a cooling film is to be formed. According to the invention, the pattern is formed in at least one subregion of defined size of the inflow surface, from a plurality of identical isosceles triangles, which are defined by a minimum spacing (k) and by a mean diameter (a) of the inflow openings correlating to the minimum spacing (k). This procedure reduces the complexity of the design process.

Method for manufacturing an engine component with a cooling duct arrangement and engine component

A combustion chamber assembly group, and a mounting method therefor, includes a combustion chamber for an engine that includes a curved combustion chamber wall extending along two spatial directions, and a combustion chamber shingle affixed at an inner side of the combustion chamber wall and having a shingle edge defining the outer contour of the shingle. For an at least sectional abutment of the shingle edge at the combustion chamber wall with a minimum clamping force in an operational state of the engine, the shingle is mounted to the combustion chamber wall in a mounting state in which the shingle at least at one section of the shingle edge has a curvature with respect to at least one of the spatial directions that differs from the curvature of the combustion chamber wall with respect to this spatial direction.

The present invention relates to a combustion chamber head for a gas turbine with at least one combustion chamber wall a metering panel at least one heat shield at least one sleeve and a cowling characterized in that the metering panel forms one part with the combustion chamber outer wall and the combustion chamber inner wall in that the heat shield is mounted onto the metering panel from the downstream side of the metering panel in that the sleeve is mounted to the metering panel from the upstream side, and in that the cowling is separably attached to the metering panel

Combustion chamber head for a gas turbine

In a gas turbine engine, the exit end of a combustion chamber of annular shape is suspended from the interior wall of the engine casing by an elbow structure which is detachably mounted on a flange by one of its two legs; the resilience of the elbow structure is improved by dove-tail shaped openings provided in the elbow structure with the narrowest section of the openings facing the bend line of the elbow structure to define with the opening of the other leg a gap that enables the elbow structure to function as a leaf-spring.
