Aircraft nacelle provided with at least one thrust reversal device comprising at least one longitudinal deflector, aircraft comprising at least one propulsion assembly composed of such a nacelle

An aircraft nacelle comprising:

• an external surface extending between an upstream end and a downstream end and which is configured to channel an airflow 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 spaced apart from the upstream end and the downstream end and which passes through the nacelle,
• at least one mobile part configured to adopt a first position corresponding to an inactivated state of the at least one thrust reversal device and in which the at least one mobile part closes off the at least one lateral opening, and a second position corresponding to an activated state of the at least one thrust reversal device and in which the at least one mobile part at least partially opens up the at least one lateral opening,
• at least one diversion system configured to adopt a first position when the at least one thrust reversal device is in the inactivated state in which the at least one diversion system does not interfere with the airflow channeled in the nacelle, and a second position when the at least one thrust reversal device is in the activated state in which the at least one diversion system interferes with the airflow channeled in the nacelle and orientates the airflow in radial directions toward the at least one lateral opening, and,
• at least one orientation system which is configured to orientate the airflow diverted by the at least one diversion system, wherein the orientation system comprises:
• at least one transverse deflector positioned approximately in a plane perpendicular to the longitudinal direction and which is configured to orientate the airflow diverted by the at least one diversion system in the radial directions and toward the upstream end of the nacelle, and,
• at least one longitudinal deflector secant to the at least one transverse deflector and which is oriented in a direction which forms an angle of less than 25° with the longitudinal direction.
