Fuel injection device for a gas turbine

There is described herein a fuel injection device for a gas turbine, comprising a plurality of streamlined bodies (30) arranged in a ring adjacent to one another in a circumferential direction relative to a central axis of the fuel injection device, each streamlined body (30) comprising a trailing edge (34) and at least one streamlined body (30) comprising a fuel nozzle (32) on the trailing edge (34), wherein the plurality of streamlined bodies (30) is split into at least a first group of streamlined bodies (30) and a second group of streamlined bodies (30), all the streamlined bodies (30) in the first group being the same and being different from the streamlined bodies (30) in the second group and all the streamlined bodies (30) in the second group being the same, wherein the first group of streamlined bodies (30) comprises at least two streamlined bodies (30) adjacent to one another. Alternatively, the streamlined bodies are clustered in sets of two adjacent streamlined bodies, and in which at least one of the sets is different from the other sets. Alternatively, the streamlined bodies are arranged such that the fuel injection device has a maximum of four-fold rotational symmetry in the plane perpendicular to the central axis. A method of use and a method of design are also described.
