A propelling nozzle for an aircraft engine has an interior shroud of high thermal conductivity which is penetrated by a number of cooling ducts and is surrounded from the outside by a solid support shroud. A cast-in intermediate layer is provided between the interior shroud and the support shroud. This has the advantage that manufacturing tolerances of the interior shroud and of the support shroud may be compensated. Only very minimal demands must be made on the accuracy of shaping the interior shroud and the support shroud.
