An aircraft includes at least one net for reducing aerodynamic noise from a structural element of the aircraft. The flexible net associated with the structural element is retractable and capable of occupying at least one position located between the following two end positions: a deployed position, in which the net is placed in a turbulence area, and a retracted position, in which the net is at least partially outside the turbulence area. The net may be automatically moved between positions based on an aircraft parameter such as speed or altitude.

A streamlined profile reducing the speed deficit in a wake, a pylon with such a profile, a propulsion assembly including such a pylon and an aircraft including this assembly. The profile has a device for suction of air from the boundary layer formed on this profile. This suctioned air is discharged with the aid of a nozzle the outlet of which is situated close to the trailing edge of the profile. Suction of the air and discharge thereof contribute to reducing the speed deficit downstream from the profile and therefore to reducing the turbulences in this zone.

According to the invention, at least part of the edge of the hole is loosely surrounded with a mesh structure so as to create a space between the latter and said edge part.
