Abstract

A fan for an aircraft engine, particularly a gas turbine aircraft engine, is disclosed. The fan has a fan rotor with fan blades, which extend radially outwardly from a hub to an outer flow path wall of a fan flow path. The fan has an auxiliary rotor that is positioned upstream of the fan rotor and has auxiliary blades that extend radially outwardly from a hub and end at a distance from the outer flow path wall of the fan flow path. The auxiliary rotor and the fan rotor are designed as separate rotors, such that the auxiliary rotor can be operated at a higher speed than the fan rotor.
