Claim 6:
7. A method for discharging a hot air flow from an air intake, of a nacelle of an aircraft turbomachine extending longitudinally along an axis X in which an air flow circulates from upstream to downstream, said air intake comprising a lip extending upstream, a downstream part and an internal partition wall separating the lip and the downstream part, said lip comprising an internal wall facing the axis X, an external wall opposite to the internal wall and an upstream wall connecting the internal wall and the external wall and delimiting with the internal partition wall an annular cavity, said downstream part comprising a downstream internal wall and a downstream external wall as an extension of the internal wall and the external wall of said lip respectively, and delimiting between them an internal volume, said air intake comprising: — a de-icing device comprising at least one duct for injecting a hot air flow into the annular cavity of the lip, — at least one passage opening formed in the internal partition wall, — at least one outlet opening formed in the downstream external wall of the downstream part of the air intake, and — at least one discharge conduit, mounted in the internal volume of the downstream part, configured to conduct the hot air flow from the passage opening of the internal partition wall to the outlet opening of the downstream external wall so as to discharge the hot air flow outwardly of the air intake, the discharge conduit comprising a first end connected to the internal partition wall, a second end connected to the downstream external wall of the downstream part and a main body extending between the first end and the second end, the main body comprising a downstream portion and an upstream portion, the downstream portion being elastomeric, the upstream portion of the main body being rigid, the method comprising the steps consisting in: — injecting a hot air flow into the annular cavity of the lip, and — conveying the hot air flow from the passage opening of the internal wall to the outlet opening of the downstream external wall, so as to discharge the hot air flow outwardly of the air intake.
