  • Streamlined profile reducing the speed deficit in its wake
    Patent number: 8596574
    Abstract: 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.

  • STREAMLINED PROFILE REDUCING THE SPEED DEFICIT IN ITS WAKE
    Publication number: 20120273609
    Abstract: The invention relates to a streamlined profile reducing the speed deficit in its wake, a pylon comprising such a profile, a propulsion assembly including such a pylon and an aircraft including this assembly. The profile comprises a device (40) for suction of air from the boundary layer formed on this profile. This suctioned air is discharged with the aid of a nozzle (48) 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.
