Abstract: A turbofan engine for a civil supersonic aircraft, including: an engine intake; a multi-stage fan that is arranged behind the engine intake; a core engine that comprises a compressor, a combustion chamber and a turbine; a primary flow channel that leads through the core engine; a secondary flow channel that leads past the core engine; an adjustable converging-diverging thrust nozzle that forms a nozzle throat area and a nozzle outlet area, wherein at least the nozzle throat area is adjustable; and a thrust reverser that is integrated in the adjustable converging-diverging thrust nozzle.

Abstract: A turbofan engine for a civil supersonic aircraft, including: a multi-stage fan, wherein each stage of the multi-stage fan has a fan rotor with rotor blades and a fan stator with stator blades; an inlet flow channel that leads through the fan rotor of the first stage of the multi-stage fan; a primary flow channel that leads through a core engine of the turbofan engine; and a secondary flow channel that leads past the core engine. The inlet flow channel divides into the primary flow channel and the secondary flow channel. It is provided that the fan rotors of all stages of the fan are arranged in the inlet flow channel before it is divided into the primary flow channel and the secondary flow channel.
