Rear assembly of an aircraft turbojet engine nacelle comprising a thrust reverser with sliding cascades

A nacelle rear assembly of a nacelle of an aircraft turbojet engine, the nacelle rear assembly extending along a longitudinal central axis (A), and the nacelle rear assembly including a thrust reverser with sliding cascades, the nacelle rear assembly comprising:

• a sliding cowl axially mounted movable in longitudinal translation from front to back, between a closing position in which the sliding cowl provides aerodynamic continuity of the nacelle, and an opening position in which the sliding cowl opens a passage for directing an air flow coming from a cold air flow path of the nacelle;
• and
• a cascade of vanes comprising a plurality of blading rows each extending about the longitudinal central axis (A) and arranged longitudinally from a first front blading row to a last rear blading row, each blading row, except the last rear blading row, including at least one deflection blade having a curved shape and defined by a concave front face and a convex rear face to direct the air flow forward and toward an outside of the nacelle rear assembly of the nacelle, the cascade of vanes being secured in displacement to the sliding cowl,
• wherein the sliding cowl includes a front end and an overhang extending forwardly from the front end, the overhang of the sliding cowl provides aerodynamic continuity with the nacelle when the sliding cowl is in the closing position, the overhang and the front end defining a recessed portion, and
• wherein the cascade of vanes include at least one neutral blading row interposed between the last rear blading row and the front end of the sliding cowl and including at least one neutral blade disposed in the recessed portion and surrounded by the overhang, the at least one neutral blading row and the last rear blading row jointly delimiting a leakage passage toward the outside of the nacelle rear assembly and a force exerted on the at least one neutral blade by the air flow through the leakage passage is devoid of an axial component oriented backward.
