The invention relates to an aeronautical propulsion unit comprising a central engine (3), an upstream series and a downstream series of blades (9, 6), the blades (90, 60) of at least one of these series being adapted to be driven in rotation about the central longitudinal axis (X) by a turbine, and a nacelle (5) which encloses the central engine. At least some of the blades of the two series are variable-pitch blades. At least one of the blades (90) of the first series of blades (9) has a trailing edge have corrugations (93), and/or at least one of the blades (60) of the second series of blades (6) has a leading edge having corrugations (63).
