Abstract

The invention concerns an aircraft engine with an intake cone and a fan stage coupled thereto with a plurality of fan blades, wherein the fan blades are each connected to a drive shaft via a connecting means, whereina sealing device for blocking air is arranged between a blocking air space and the interior of the intake cone, and during operation of the aircraft engine a leakage air stream flows out of the blocking air space via the sealing device, characterized by at least one outflow means for the leakage air stream in a component of the aircraft engine to allow a flow of the leakage air stream into the interior of the intake cone.
