Nozzle for a gas turbine engine with baffles

The nozzle (1) has nozzle-type and diffuser-type guiding devices (10, 20) alternately arranged in a circumferential direction of a nozzle surface area (4). Each guiding device comprises an azimuthal guide wall forming a trailing edge. A wall element connects one of the nozzle-type guiding devices and one of the diffuser-type guiding devices. Each wall element includes an edge to one of the walls, another edge diverging to the former edge in an axial direction to one of the guide walls and a front-side trailing edge, where the wall elements have a curved course in the axial direction.
