An outlet nozzle for a jet engine has a gas intake and a gas outlet, at least one opening being provided through the nozzle boundary wall for the injection of a fluid into the nozzle in a direction perpendicular to one plane, for the purpose of controlling the direction of a gas flow from the jet engine so that vectoring occurs substantially tangentially in this plane. A first opening configuration is provided through the nozzle boundary wall on a first side of the nozzle center line and a second opening configuration is provided through the nozzle boundary wall on a second side of the nozzle center line. At least one of said first and second opening configurations has a substantial extension in the axial direction of the nozzle, in order to permit selective injection of the fluid through said opening configuration to a varying extent in the axial direction of the nozzle.
