Nozzle for feeding air and liquid fuel into a combustion chamber, and engine

A nozzle for feeding air and liquid fuel into a combustion chamber, in particular of an engine of an aircraft, having a nozzle main body aligned along a nozzle longitudinal axis, in which the following are arranged:

• at least one first air duct running on and/or around the nozzle longitudinal axis,
• at least one fuel duct, which is arranged radially on the outside, in particular in an annularly encircling manner, around the first air duct and has a downstream end portion running axially-radially in the direction of the nozzle longitudinal axis in the direction of flow, and
• at least one second air duct, which is arranged radially on the outside, in particular in an annularly encircling manner, around the fuel duct,
• wherein the fuel duct emerges by means of a fuel outlet opening at an adjoining, at least substantially axially aligned film applicator surface having a downstream trailing edge, wherein the film applicator surface surrounds the first air duct at the downstream end,
• wherein a length of the film applicator surface between the fuel outlet opening and the trailing edge is between a factor of 5 and 6, preferably a factor of 5.5, times a height of the end portion of the fuel duct.
