1. An aircraft nacelle comprising:
an upstream end and a downstream end, the aircraft nacelle configured to channel an air stream flowing in a longitudinal direction from the upstream end to the downstream end; and at least one thrust reversal device which comprises:
at least one lateral opening, which is remote from the upstream and downstream ends, which passes through the aircraft nacelle, and which is delimited by upper and lower edges,
at least one movable part configured to occupy a first position, corresponding to an inactivated state of the at least one thrust reversal device, in which the at least one movable part shuts off the at least one lateral opening, and a second position, corresponding to an activated state of the at least one thrust reversal device, in which the at least one movable part at least partially clears the at least one lateral opening,
at least one longitudinal actuator, which passes through the at least one lateral opening and is configured to move the at least one movable part,
at least one deflection system configured to occupy a first position, when the at least one thrust reversal device is in the inactivated state, and a second position, when the at least one thrust reversal device is in the activated state, in which the at least one deflection system interferes with the air stream channeled in the aircraft nacelle and orients the air stream towards the at least one lateral opening,
at least one orientation system configured to orient the air stream deflected by the at least one deflection system, wherein the at least one orientation system comprises:
at least one transverse deflector positioned approximately in a plane perpendicular to the longitudinal direction and configured to orient the air stream deflected by the at least one deflection system towards the upstream end of the aircraft nacelle, each transverse deflector having first and second ends respectively connected to a support at the upper and lower edges of the at least one lateral opening, and, for each longitudinal actuator, a hollow longitudinal deflector, which is configured to house the longitudinal actuator and has an aerodynamic profile that has a leading edge oriented towards the at least one deflection system;
wherein each longitudinal deflector is connected to each transverse deflector and comprises first and second walls; and
wherein at least one of the first and second walls of the longitudinal deflector has a curved profile; and
wherein each of the first and second walls has an inner edge and an outer edge that is further away from the at least one deflection system than the inner edge is, the inner edges of the first and second walls being contiguous so as to form the leading edge, the outer edges being spaced apart, wherein the first and second walls of each longitudinal deflector form a V shape at the leading edge in a transverse plane.
