Abstract
According to the invention, fitted into the slot (20) between the suction face side (32) of a wing (6) and said ventral fairing (10) is a seal (22), the internal face (26) of the free end (28) of the lip (24) of which comprises at least one boss (30) able to keep said lip locally away from said suction face side (32) to form a controlled leakage of air passing through said slot (20).
Claims7
An aircraft comprising:
- a fuselage and a fixed wing structure comprising two wings which are opposed with respect to said fuselage;
- a ventral fairing in the form of a cradle, fixed to the underside of said fuselage, where said fuselage meets said wing structure, and provided with two longitudinal upstands reaching up the sides of said fuselage, said longitudinal upstands each being provided with an opening for the passage, with clearance, of the corresponding wing so that a peripheral slot is formed around each wing, between the wing and the periphery of the corresponding opening;
- and
- a seal fixed to the periphery of each opening to plug said slot and comprising an elastic lip having a free end operable, via the internal face of said free end, to press against the corresponding wing, wherein,
- facing at least part of a suction face side of each wing, said internal face of the free end of said lip comprises at least one abutment boss able to keep said lip locally away from said suction face side so as to form a controlled leakage of air passing through said slot.
