  "textContent": "The nacelle has a lip prolonged by an interior pipe forming an air intake. A front frame delimits an annular duct (40) in which hot air circulates, and a panel treats sound from an outer side toward an inner side of an acoustically resistive layer. A pipe (98) is provided with an opening (100), which emerges into the annular duct such that the hot air is conveyed to the panel. The opening guides the hot air according to a referred direction (102), which forms an angle (beta) lower than 60 degree with a flow direction (42) of the hot air in the annular duct.",
